    Full Review: ITUO WIZ 1 & 2 900 Lumens USB rechargeable and wireless bicycle light-wiz9004sprints.jpg

    Back in January 2015, I was given the chance, as well as 5 other cyclists from MTBR forum, to test and send feedback of a prototype bike light from ITUO, a new cycle light manufacturer. The MTBR forum can be found at:
    ITUO Wiz800: 5 sets giveaway; cordless, 800 lms, usb rechargeable
    My review can be seen on : ITUO WIz1 800 lumens cordless USB rechargeable bike light evaluation

    The cycle light was a single XM-L2 with a USB rechargeable and internal and replaceable battery. 

    A few weeks ago, ITUO sent me two updated WIZ1, with one of them being in the WIZ2 configuration. The lights have kept their general looks but have had some improvement on the weaknesses mentioned during the review and forum feedbacks. 

    My new review is for the WIZ1 and WIZ2 as the hardware & software are identical with the only differences being the battery tubes and batteries. 

    The WIZ1and WIZ2 are 900 lumen single XM-L2 LED bike lights powered by 26650 or 18650 li-ion battery with on board USB chargeable capability, a GO-PRO compatible mount and a likeable interface.

    What's in the box
    Both, the WIZ1 and WIZ2 do come in identical boxes, a natural cardboard colour with a black insert, covered by a white sleeve. I appreciate it is only a box, but the feel and look inspires quality. Once open, the lights and accessories are well protected by a cut out white foam insert.
    The lights received were pre-assembled with the battery in tube. A USB cable is provided as well as a "Wise" GoPro compatible bar mount and an instruction sheet.

    Initial overview and feel
    As soon as you pick up the WIZ1 & 2 you realise that this bike lights will also double up as a flashlights (Torch for us English). They have a cylindrical shape with no sharp edges and do tailstand. The WIZ2 is more pocket friendly due to the smaller body tube and lighter in weight, but for me the WIZ1 has a better hand grip due to size and shape of the battery tube. The anodizing is flawless for both lights. The WIZ1, I received in blue and the WIZ2 in a brown finish which is not available as they only list blue or black. My WIZ2 sample was actually marked with WIZ1 logo, which does not matter as only the battery tube and battery are different. The markings are very minimal and are one side of the head with the manufacturer's name, model and web address all in crisp white lettering. On the opposite side is the USB port covered by a rubber plug with a double lip acting as water seal. Positioned on the top is the switch with integrated battery gauge light. The cooling fins are also quite minimal and are positioned behind the bezel. The body tube is where the WIZ1 differs from the WIZ2. Both have square clean threads and a single "o" ring. The WIZ1does have a much bigger tube to accommodate the 26650 4500mAh battery. Both tubes are made a little larger than the battery supplied presumably to accommodate a higher capacity battery in the future? The tension spring is at the bottom of the tube and the positive terminal in the head is spring loaded, so the battery does not rattle on rough trails. Half of the quick release bracket is cast in the body of the light and just forward of it, appears to be a mounting point for a lanyard, which is a good idea if used as flashlight or an helmet light.

    The "WISE" bar mount uses the GoPro system and does not require different rubber spacers for use on a 25.4 or a 35mm bar.

    The lights are supplied with Ituo's own batteries which are clearly marked with + and - . They are of the raised positive terminal which make it easier to do a battery change in the dark and appear to be of good quality.

    Settings (from the manufacturer website)
    Light
    CLICK: quick press of the switch less than 1 second
    DOUBLE CLICK: two rapid clicks of the switch
    PRESS: 2 seconds press of the switch
    LONG PRESS: 3+ seconds press of the switch
    . A CLICK from the OFF position will always turn the light on to the last steady mode used.
    . A CLICK from the ON position will cycle through the steady modes low, med, high.
    . A DOUBLE CLICK from ON or OFF position will access the last flash mode used, a further single CLICK will allow you to cycle through the flashing modes day flash, night flash, warning flash.
    . A further DOUBLE CLICK will return the light to what ever mode it was prior to activating the flash modes, this could be ON, OFF or THE HIDDEN 50 
    LUMENS MODE
    . A PRESS from on or off, will access the 50 lumens hidden safety mode.
    . A LONG PRESS will turn the light off (it will go through the 50 lumens hidden mode first). The light as a memory and will remember the last steady or flash 
    mode used.
    . The 50 Lumen mode is also very useful during stops to let the light cool down while still having some illumination.

    Safety 
    Back up/safety mode: when the battery power is less than 10%, the light will turn to 50 lumens as back up illumination for 30 minutes before turning off automatically.
    WARNING: the backup/safety mode is only for emergency and we advise users to recharge the battery before this is activated. When the light turns to safety mode, the light can only be turned off or on by one click, and other modes can’t be operated.

    Charging (from the manufacturer website)

    The battery is shipped approx 50% charged and it is advisable to fully charge it before use. The charging time will depend on the uncharged sate of the battery and the method of charging, this could take up to 11 hours with a 500mA charger and 5 hours with a 1A charger. Once the battery is charged, the light will turn to green, please disconnect the charger from the mains and from the battery. Do not leave the battery unattended while charging.
    Please try to avoid totally draining out your battery and do not leave your battery flat for any length of time.


    ***PLEASE NOTE ALL ABOVE WRITING IN BLUE ARE SPECS DIRECT FROM THE MANUFACTURER***

    Riding with
    Time to turn the light on. The operation of the switch is positive and easy to use with or without gloves. The interface is very intuitive with minimum clicks required to navigate it.
    You have 3 continuous power outputs obtainable by a single click from off. They are well chosen and can be easily changed while cycling. In any of the modes you can turn off the light by a single long press of the switch. A very useful feature is the access of a low/safe mode just before turn off. I have found this very useful when low light is only required. ie car park or side of a trail when chatting with your mates. The WIZ has a memory so whatever level you are on when you switch your light off, it will return to this setting when switching on. 
    You have 3 options for your flashing modes all accessible by a double click. The flash modes are well chosen with a double and a single flash at the right speed together with a pulse mode, which is a constant light with a bright pulse. The latter is very useful for road cycling where you want to see and be seen. A double click will return you to steady mode or a long press (about 3 seconds) will turn it off after going though the safe mode.
    I must say this is one of the best interfaces I have used so far, easy to operate and to remember. One single long press to switch off from any of the modes with a very useable low mode prior to light off.
    The beam is wide enough and has a good throw with a neutral tint which is a good choice for cycling as it does not create harsh shadows like the cool tint LEDs does. 
    The WIZE clamp is very easy to attach to your handle bar and the light can be removed or fitted single handed. 

    The only thing I notice while cycling with both lights, was a rattling coming from the quick release connection from the clamp to the light. The WISE clamp connects very firmly on my 35mm bar but is not very tight on my 25.4mm handle bar allowing the light to be moved by hand slightly from left to right or up or down as the jaws of the clamp are bottoming.
    Full Review: ITUO WIZ 1 & 2 900 Lumens USB rechargeable and wireless bicycle light-imag3578.jpg

    Wrapping a little black electrician tape around your bar to make it thicker will improve the tightness of the clamp on your handlebar. So a little improvement is needed on this clamp! During the output/run test, I notice that the sprint 900 lumens setting steps down after about 7 minutes to a level just above 70% of its original output. Once at that level the light is well regulated for the next two hours for the WIZ1 and about an hour for the WIZ2. The step down happens at the same time with both lights irrespective of what capacity batteries you are using. The step-down appear to be activated by a timer. If the battery has enough charge, you can switchback the WIZ to the higher 900L, Sprint level for another 7mn. In real life while cycling the difference of output is barely noticeable, and I was happy enough with the sprint stepdown. The charging was easy and in line with the time given using my HTC 1 amp mobile phone charger. Higher output tablet chargers (1.5Amps) can also be used.
    By purchasing GoPro accessories from the net, I was able to fit the WIZ1 on my lid to see if this would make a good helmet light. I did a MTB club ride with just two WIZs both in the WIZ1 configuration and I was surprised how well this set up works. I usually ride with a twin XM-L on my lid and quadruple one on my bar and despite the fact the two WIZ did produce a lot less lumens (about half), the beams where very well balanced with a very neutral tint and I felt that the light given was very user friendly and I did not miss the extra power. A plus factor was not being wired in when I removed my helmet (I always ride hot and my helmet do come off often during stops). Careful placement is required as not to unbalance your helmet toot much. 

    The WIZ 1 & 2 does the job well for a single XM-L light and allow you to go wireless. As a bar light, I have found one to be sufficient for road ridding but for mountain biking you do need to run them as a pair.



    Home test

    The ITUO WIZ lights were tested with my home made light sphere and a cooling fan was used between the readings (please note there will be a small margin of error for the readings as the light was removed and repositioned on the sphere for the various readings). As this is a home-made integration sphere, I cannot make any true claims as how close my result would be to results coming out of a lab integrating sphere costing thousand of pounds, but this does give a rough idea as how the light performed and enables you to monitor the output versus runtime.

    The test/monitoring was started 2 mins after initial turn on and is in line with ANSI method of testing flashlights

    The graph shows that once the step down has happen in the "sprint mode", the WIZ1 is very well regulated for a couple of hours, the result is not as good with the 18650 battery only giving you about 45mn of full regulation.

    On the left of the WIZ1, you can see another light, which I took with me that night to make some comparison shots, the light is one of the unbranded Chinese light running 5 XM-L usually quoting around 5000 lumens, the photo setting are the same, you can easily see the difference in tint from the 5-XM-L cool white to the WIZ1 neutral white, both are on full power.

    Small video showing the different flash mode, very sorry , but the quality is not that good, but you can still see that the flash modes are proper use able modes

     

    For: Good beam, USB rechargeable, replaceable battery, good run time for the WIZ1, good output for an internal single battery light, very good interface with a good choice of light levels, GoPro compatible mount, good safety feature, can be use for other activities and will tail stand to be use as a candle.

    Against: step down too soon, no helmet mount provided or available from the manufacturer. (but easily obtainable from the net which is what I have done)

    *****

    For a newcomer in the cycle light market, ITUO have produced what I would consider a high end wireless light for a reasonable price. Using it, you quickly realise that this is a proper cycling light with useful features. 
    For me, single LED lights are well suited for road cycling and daily commuting when not so much light is required and where size, weight and ease of use are more important.
    Having just a single LED has its limitations as a mountain bike light but if you are looking for wireless bike lights set up with replaceable batteries, this is well worth looking at. Running them as twin set up: bar and helmet lights, and once properly adjusted, they provided me with a good workable and neutral beam during one of our forest night ride.

    The WIZ 1 & 2 are very user friendly cycle lights, which will also double up in the summer as a flashlights.
    As to which one to choose, this depends on your specify requirements; weight/size versus runtime. 
    I think this is a very serious competitor to lights like the Cateye Volt 800, Exposure Joystick and other high power single LED wireless bike lights.

    I am certainly looking forward to seeing more products from ITUO.
    The two lights have been sent to me direct from China by the manufacturer for review, so at the present time, I am not aware of local UK retailers. I also understand that the light retails at $99.95 for the WIZ1 and $89.95 for the WIZ2
    prices from ITUO website http://www.ituoworld.com

    Personal notes regarding lights. 
    I am a MTB ride leader with my local cycling club in the South of England and an independent - occasional LED lights reviewer. I also ride to work every day; sun, rain or snow. The lights I reviews, are not necessary my own choice of lights for my riding, but I have tried and tested them in real cycling. Choice of lights are very personal and the type of ridding you do should influence the type of light you choose. Factors like; run time, light levels, type of flash modes, LED tint, size, bike attachment, way of recharging the battery, usability when off the bike can be as if not more important that the number of LEDs and number of advertised lumens. More is not always better!


    14 Nov2015 update
    I have just received an email from a firm brightbikelights.com to let me know that they are the UK distributor. Great news for UK riders.

    Since the clocks went backwards here in the UK, I have been using my two sample lights during my daily commute (DONE AT NIGHT ON LIT ROADS)

    Wiz1 is on my bar and WIZ2 on my helmet.
    this is my preferred settings for my commuting
    day time helmet light in the twin flash mode, bar off
    night time helmet light in medium mode and bar light in the warning flash mode(this is a constant mode with a pulse).

    Nice review. I have a couple of questions.

    You say made your own integrating sphere, so shouldn't you get the total lumens as the output? Your chart says lux, I always thought that was intensity at a spot. 

    What's the difference in length of the two lights? The wiz 2 is the better light, but you say it's cheaper?

    How secure is the mount when you go over some big hits?

    The charge time of 7 hours (1 amp charger) seems excessive on the wiz 2 (I think you labeled them wrong on the blue part). Can you cut it in half with a 2 amp charger?

    A 30% drop in brightness after 7 min is pretty big in my opinion. What's the point of this? 

    I like to switch modes by rapidly clicking, so would I accidentally double click and get into the flashing modes? That would annoy the hell out of me.

    Varider, hope this helps:

    Lux is actually the measure of light output. Lumens if I understand it correctly is nothing more than lux over a given area. So in a sphere its a simple calculation to convert to lumens. Something to to with total volume of the enclosure or sphere in this case.

    What you thinking of for spot intensity is Cd/Lm (candela/lumen I think is how its said) Which is a measure of basically how much of each lumen output is concentrated in the spot. Only used for rating optics and reflectors. Im not sure how the "number" actually works yet,gotta read up on the fine details of that at some point. But it represents lumens output in the "viewing angle" vs the lumens in the spill.

    7% drop IMO isnt bad for a bench test. Once the casing heats up to "running temp" output is going to drop. Emitters at 25C vs 85C for their output. Im also betting he wasnt testing with much if any airflow, its a flashlight after all. I can bet if I put a yinding on a sphere without airflow, youd see more than a 7% drop over the course of the few minutes before thermal protection kicked in.

    Yes, nice review. Makes my job easier when ( or if ) I get one to review. The auto-power down is a typical torch function. You see this type of thing on other torches as well when they use more intricate UI's. My understanding is that it is used to help conserve battery power. In most torches it is set-up to engage in just a couple minutes. If this one is set-up for 7 minutes I think that is long enough for any fast hill unless you are riding down a mountain.

    About the double click: Likely this is not going to happen but it can. The same thing is possible with the Nitefighter BT21 and Gloworm X2 ( v3 )

    Hi Varider, 
    You say made your own integrating sphere, so shouldn't you get the total lumens as the output? Your chart says lux, I always thought that was intensity at a spot. 

    The Integration sphere I build is a cheap DIY light box build out of a 12" polystyrene globe, this was done a long time ago when I use to ride with cheap flashlights/torches powered by 2200 mAh, I was very interested in the light overall run time and behaviour and to make a comparison of the different lights I was trying. I have kept to the same formula, ie wanting to know the behaviour of the light under load. As I am sure you are fully aware, some manufacturer and to be fair mostly the cheap ones do advertised ridiculous lumens outputs which are just theoretical figures and have no relation with what you do get out of your light. I did a lot of reading when I first build my box, but came to the conclusion that unless you have a proper lab and £1000s of pound worth of equipment you can not give a Lumen figure. My sphere is a DIY one which I use with a cheap LUX meter so can not I vouch for the accuracy of them. My figures and graphs purpose are to make comparative measurements with various lights that I test.


    What's the difference in length of the two lights? The wiz 2 is the better light, but you say it's cheaper?
    They are identical in length, It is a little confusing as the WIZ2(18650) they send me is actually marked with the WIZ1 logo (26650). I have checked with the manufacturer and the both heads are identical in specs, only the type of body use determine if the light is a WIZ 1 or 2. So to recap the WIZ1 is the dearer one with the 26650 battery and the cheaper one is the WIZ2 with the 18650 battery

    How secure is the mount when you go over some big hits?
    Very secured on my Giant with the 35mm bar, but on my Specialized with 24.5 mm, I run of adjustment to have it very tight, so the light can be moved by hand, I only now ride in the forest with my Giant so I have not had any problems.

    Photos showing the clamps bottoming, this can be sorted by slightly thicker rubber pads, a piece of inner tune or building the bar with black pvc tape to increase OD

    The charge time of 7 hours (1 amp charger) seems excessive on the wiz 2 (I think you labeled them wrong on the blue part). Can you cut it in half with a 2 amp charger?

    All the specs in blue are straight from the manufacturer website (all blue writing in my review). I think I recall getting about 5h charging time from HTC mobile phone charger on a flat 26550 battery. (Wiz1) I did ask the question to ITO regarding using 2 amp charger and the USB charging rate is fixed to just below one amp, so you will not get a quicker charge. I went on their website and they do list 7h on their specs sheet but 5 hours in their operation page, so there is a miss print in their specs sheet Wiz1-Wiz1-ITUO

    A 30% drop in brightness after 7 min is pretty big in my opinion. What's the point of this? Ituo did monitor the last two threads back in January and they were pretty good for answering questions raised. So I let see if we get a reason for this. I am sure myself it is due to technological reason. I have come across a lot of single LED lights running turbos at similar output and they all step down to a lower output within a few minutes.

    I like to switch modes by rapidly clicking, so would I accidentally double click and get into the flashing modes? That would annoy the hell out of me.

    This has not happen to me and I had a the opposite problem of not being able to double click quick enough while riding to change from constant to flash. I must say that, the only light mode changing I do, is when I go up the big fire trails, I was using there safe mode and on all the other single tracks I do, I use the race or sprint mode. For me once in the forest, the difference to my eyes between the sprint mode and the step down mode which is just above 70% of it original output is not that much and I can not really recall when this happen on a trail. This is of course very visible in the light box test and less on a trail, but there is a difference.

    I hope this help.

    All test I done with a fan, I don't want to burn out my lights :-) this is another reason why there is a little discrepancy between the readings as the light is in front of a electric home fan then taken out and placed in the integrating sphere window where a recording is done, then placed back in front of fan.

    You are right, one of my usual set up is the Glowworm X2 on my lid and I have gone into programming modes before by clicking the switch to quickly! as said, I have not had this problem with the WIZ

    Something else I forgot to mention during the review is the battery light has only got two settings, green and red, I have highlighted this in red to give you an idea of how much run time you have when the light turns red, this is of course out of a new battery and run time may differ slightly from one to another light/batteryFull Review: ITUO WIZ 1 & 2 900 Lumens USB rechargeable and wireless bicycle light-wiz900rundata.jpg

    I have just posted on youtube a video of the flashing modes that I took another night, again not perfect as the video is darker that what my eyes did see, best I can do for the moment, this is a time consuming trial and error process. 

    https://youtu.be/kxtDs5SbhLY

    This a user friendly light which has already replaced my Fenic BC30 on my commuting bike, a lot easy to recharge at work, I have been using the double flash during the day light hours.

    Skyraider59, thanks for the explanations. 

    So your integrating sphere is a big white ball with a lux meter attached. You don't move the meter relative to the light, it's stationary? Is the light shining directly at the meter?

    You say the mount doesn't tighten on a regular 25 mm handlebar. Do the ends of the clamps hit each other making it impossible to further turn the screw, or is there something wrong with the screw itself? I was thinking of buying one of these mounts separately, but if it doesn't work on the smaller bars it's useless to me. 

    That 30% drop bothers me, especially if it's on timer. I could understand if it's a thermal/safety drop down, but not if it's designed to drop down after a certain amount of time. It's a bike light, it should be able to run on the highest setting as long as you are riding at a good pace. If I remember right, the Niterider Lumina's don't have this problem, so why wouldn't someone just buy one of those instead?

    tigris, perhaps you are right, but from what I remember reading is that that you just integrate lux over a sphere to get lumens. This obviously means that you need the lux measurements at all points of the sphere. If the light has circular symmetry, I think you can just measure the lux on a line through the center of the hot spot and then use those values in a one-dimensional integral.

    I did my integrating sphere as per instruction from this CPF thread, mine is minus the wood box, the lights shine from the top, the LUX meter is at 90 degree to the source of light with a baffle to stop the light shining in the LUX meter, the meter stay on the sphere but the light get removed after each readings and are placed in front of fan . Here is the tread link Building an Integrating Sphere ...

    Nothing wrong with the mount, contrary, I think it is a good mount, they supply only one set of rubber inserts, which in my mind are a little too thin. The mount tighten ok, it is just not dead tight on 24.5 bar, the two jaws bottom up and prevent you to give that extra tightness. All I have done on my my bike with the 24.5 bar is build the bar up with some black electrician tape were the clamp fit, very easy mode. I think the manufacturer has tried to make our life easier by supplying just one set of rubber pads to do it all. I have some lights were you need to change the rubber pads when you fit their clamp on a 25mm or 35 mm bar, and it is a pain in the "A..s" as I can never remember were the other set is! (got a lot of lights and lights bit in a draw :-) I certainly would not dismiss the mount for such a minor and easily rectifiable point. Will take some photos if you want, to show you

    Varider, like you I dislike the step down and would prefer the light to stay at the original level, but I would guess that the run time would be a lot less that the 3h I have confirmed, I think the manufacturer may have made a choice output versus run time? Or may be you can not get a 900 lumens on a fully regulated light for that time, I do not know the answer. BUT if Niterider want to send me a Lumina for review I may be able to tell you why someone may buy one of WIZ instead! I have not tried the Lumina, so can not say much about it, but I had a quick look at the MTBR review and a spec page and without looking too hard, I can see already some differenc, only to name a few, run time, replaceable battery, Go Pro mount, more modes, 3 constant 3 flash, a safe mode. I work as a parts man for car main dealer and I will ask you the question as why does some people buy a small compact car and other buy a sport car or a 4WD, the same reason why there is so many cycle lights out there, because people have different requirements and what is important to one is not to an other. Like you do not like the auto step down and I am not sure why they have done it, but from testing lights I can tell you that I have come across two different behaviors, we have the lights which are fully regulated and which will have virtually the same output during most of of their run time, usually the run time is shorter that the lights which are not fully regulated, they also don't give you any warning before turning off, this in my mind is dangerous, but fully regulation is used by many light manufacturers and people are fine about this and just rely on the battery light to guess when the light will turn off on its own. You also have the other type of lights which are not fully regulated, were the output will decrease gradually until the light is just a few lumens bright, this being safer in my mind as you will not be plunged in the dark suddenly, again this is down to the rider as what type of light they prefer. 

    If it was not for people like myself and other reviewers who really test lights fully, people would not be aware of features like the step down on this light. 

    Look at the way MTBR runs their test. only 3MN! not much of a test! Step down does not happen until 7mn, so this would not be high lighted on there test

    To be in line with the ANSI method of testing I will only start my test 2mn after initial turn on, so I can can tell you that the WIZ 1 & 2 like all the other light tested will run very close to 100% ouput just after 3mn, 

    What I would be interested is to find out what is the output of the Lumina 800 after 1 hour is and of course, the turn off is at 1h30mn, not much good to me as most of our rides are 2h or plus! 
    https://www.niterider.com/product/lumina-oled-800/

    Of course I would get a lot more than 1h30m out of a Lumina as I would not run it on high all the time but do you see my point, nothing is really black or white and there is no perfect light for everyone.

    So I think it is a little unfair to say: so why wouldn't someone just buy one of those instead?

    ...And...you could also say, "Instead of a Lumina ( or any other lamp >$75), "Why not just use a cheaper torch using the same emitter"? If you shop around you can find some good deals on 18650 / 26650 torches that use the newest emitters, have quality builds, quality drivers, switches...etc...ARE, a lot cheaper and work just as well as the more expensive offerings.

    The ITUO products are just another product designed for bike use. I don't think it's the reviewers job to have to justify the purchase of the product for someone else. They just need to review the product and let the forum readers know what it has to offer. It's up to the buyers to decide whether or not it's something worth laying money down for.

    I'm not saying the reviewer can't compare the reviewed product to something else, I'm just saying you don't have to prove the reviewed product is somehow better. You've done a very good job at giving the pro's and con's of the product(s). If I get one one these I doubt there's going to be anything more I can add to the review other than just my opinion on how well the product works. You pretty much covered almost everything. 

    Oh, and about the Lumina: Not sure if the battery on those are serviceable. The Wiz products are. Not to mention you can probably use 18650's with the Wiz 1 ( 26650 model ) as well if you have a battery adapter. ( Yeah, they make those ).

    Although I have yet to see the Wiz 1 myself reportedly the mid-mode is 500 lumen. That is a very good setting for a torch using just one cell. At that setting the user will be able to see very well and still get decent run time.

    The older Lumina's you could take apart and put in another 18650 cell. I'm not sure what they are doing now. It's not something that you could do on the trail however. One thing those lights have going for them is they are remarkably small and they come with a good mount also. 

    I'm definitely a fan of user replaceable batteries (during the ride). One reason I like the Lezyne lights. Anyway, there's a huge competition for this type of all-in-one light. 

    I thought that mtbr used to test the lights until they ran out of juice and plot the output for the entire run. Maybe it's just too time consuming. 

    Ituo should suck it up and send some these lights to the main mtbr light review crew. No offense to you Skyraider. Let's see what these lights really put out. This guerrilla marketing is getting old. It's one thing if the light is a cheap Chinese light retailing for under $50, but for $110 they are playing the the big boys and they should just send in the lights for full-on review.

    Cat Man Do and Varider, thanks for both of your inputs, your are both raising some valid point about reviews in general and the lights. 
    All I will say is that a few years ago, I spend a lot of time riding with cheap flash lights with upgradeable/replaceable P60 modules and 18650 batteries, I used to buy the latest module and the latest battery to better my lights, even went to a 26650 flashlight to get more run time. 

    Yes $25, $75 or $120 single XM-L2 lights will put some good light in front of your bike, but please do look at what you are getting for your money don't stop at the light in front of you. 

    I think it is the reviewer job to highlight sometime the not so obvious to readers. I hope I do that!

    Varider, Don't get me wrong I love the MTBR shoot out, I think they are a great service to the cycling community, I love their beam shots and reviews and this did convince me to part with my hard earn cash for a Gloworm X2! 

    But check their Lumen/per minute graphs on their reviews, they are only for the first 3mn, which honestly does not tell you a lot. 

    Brilliant to have the full output and a great beam at 3mn in your ride but not so good if the Lumen/discharge line is bad and you get 50% output one hour into you ride. That type of information unfortunately you do not get from most of the reviews as this is very time consuming.
    You have to rely on the run times quoted by the manufacturer as they are not checked by a lot of reviews! 
    Again not an ideal situation to make a choice on lights, what may look as a good buy may not be as good once you have been on trails for an hour or more. 

    When I did a lux/mn test for the WIZ1, I was stuck to it for 3h 45mn, this did write off my entire evening as measurements were recorded every 5mn. 
    This why I think it is good some time to give a little more than just bare facts, passing on a little of your own experience with the product I think is beneficial to the readers.

    I am as well, for a long time this I all I used, but a search for more run time and lumens took me over the other side, but I must say that being wired in from your helmet to your ruck is a pain in the A..s! Last Friday night ride was brilliant, I did not have to worry about the damn wire every time I took my lid off and I had a spare battery in my ruck which I did not need, as we were out for a couple of hours.

    @Skyraider59 ; Do you know where these are sent from? I'm just wondering how long it will take before I get mine. 

    Damn...starting to get cold at night in my neck of the woods already. Tonight while at work I had to slip on a long sleeve wind breaker.

    Hi Cat-Man-Do, here to the UK , about 3 to 5 days by courier and if send via air mail, it usually take 2 weeks, not sure where you are in the world so don't quote me on it! Mine were send from China, I think Shenzen, but did not look at the post mark as I was pretty excited to get new lights for review, i ripped the packet open pretty fast! :-)

    I have replaced the mode video in the main body of the review by another one made on the road, quality is not brilliant but is is better than the old video firstly posted, don't forget there is a lot of street light

    We are still improving the mount. Will have a pair of better and thicker rubber pads.

    ITUO Wiz 1 CAt Review; Coming soon to a thread near you.

    Hi folks. Received the Wiz 1 just before leaving for work yesterday. I was going to just add my thoughts to Skyraider59's review thread but after some careful consideration I've decided that I will post my own review in a separate thread. 

    I think I'm going to have some interesting comments and without letting the full CAt out of the bag I'll just say at this point that my initial impression is that I'm very impressed with the Wiz 1 and *quite surprisingly so. ( *Note; I really didn't think I was going to like it ) More on the reasons why and why I now find this product quite interesting when I start the review. I should have a new thread started by next week. Hopefully the weather will cooperate and I'll be able to test it on some rides. 

    ** To whom it may concern; The "Wiz 1" was supplied to me by the manufacturer "ITUO" without cost for review purposes. Yes, I get to keep it.
