    User Review: ITUO Wiz20

    So I received a Wiz20 today from Ituo for review. Just have to say, its a really nice light.


    www.ituolights.com





    Ride Video
     

    First Impressions:

    -Nice, clean, quality light. First thing I noticed was the fast it only has a front and rear cover and the switch. No multiple layers to the housing. 

    - Rear cover is hinged with an aluminum spring latch. Very simple and straight forward to use.



    -USB charging of whatever cells you put in it. It does run on 8.4v not 4.2v which is nice to see. And yes USB charging does work perfectly. Its set up with a thick rubber cover on the bottom of the lighthead.

    -Optics are a "tight spot". Appear to be LEDDNA (as we know them) 10 deg optics. A bit tight for a bar light IMO, but still very nice. Makes for good throw while still being usable in close.



    -QR handlebar mount is similar to their Gorpro style mount in how the QR is set up and the slide lock for the light head itself. HOWEVER, not a gopro compatible mount. The mount is all one solid piece of aluminum (nicely finished I might add) with the base for the slide lock machined as part of it. Makes sense though being the weight of the head, a light weight gopro qr mount would have a hard time not tilting under the weight of the lighthead.




    Here it is mounted on my Mukluk(fat bike)





    This light has a few modes (ok more than a few). Need some time to mess with those. MAJOR POINT TO MAKE WITH THE WIZ20 THOUGH, ITS FULLY USER PROGRAMMABLE. Ya you read that right. Has a couple preset mode set ups you can select. Or you can program I believe up to 5 modes. The one issue I do have though is the mode spacing. Many of us know the KD2 yinding clone driver. Programmable modes in 10% increments. Have been trying to mess with it and seems the mode spacing per 10% is noticeable up to 40% then from there to 100% there is little change. ALmost not noticeable. Not sure if Im doing something wrong, but Im not seeing the full set of mode options. I did several checks just to make sure. Andd tried to set the light at 20-50-100 just to start and 50-100 there is little change. Doesn't seem like a 50% change, not like what we see normally.

    Output:


    I cant say its "1500 lumens" yet. My DIY integrated sphere I hope to have up and running this weekend, so this will be first light to be "reviewed" on it.

    Here's what I do know: Fenix BC30R is rated at 800 lumens on level 4 (1600 with the stupid and useless turbo button). So I light up my yard with BC30r (at level 4) and Wiz20 side by side. Wiz20 IS ALOT BRIGHTER! So close to 1500 lumens if not "spot on" is very possible.


    This is a pic of the 2 side by side. But I think we have a better option than Fenix by far. Both in output and functionality.




    All the in depth details, beam shots, etc to come over the next several days. At this point though having this light in my hand and the reviews of their single emitter lights, I think we have a very real and solid contender for the sub $150 light market. This one is $99.99 WITHOUT CELLS, $129.99 with cells.

    Technical Details Etc

    Details video



     



    OK here's the in depth specs:



    Weights:



    Head only: Claimed- 154g, Actual is 151g for mine



    Head with LG 3200mah Keeppower 18650: 251g



    Mount: 35g confirmed





    Claimed Output: 1500 lumens



    Actual Output: Visual approximation (comparison vs other lights), 1300-1400 lumens. Within acceptable range for output margin of error. Will hopefully test and get exact numbers soon


    Update: Ok lumen output over run time curve using NCR18650GA cells.





    Beam pattern: Standard 10deg PMMA TIR Optics. Confirmed these are the 10deg optics we all know. Making optics changes is VERY easy (just pay attention to seal and orings during reassembly) and giving us SEVERAL options for beam patterns. Thankfully these arent the poor efficiency optics we see in most lights. ITUO did their homework well, used the optics we all upgrade to from stock ones.





    Batteries: 18650 Li-Ion cells only x 2



    -Use of protected cells is recommended, driver does not have over discharge protection. Light can be purchased with 3100mah Cells.



    -Does have reverse Polarity protection





    Run time: 



    -Claimed: 2.3 hours on 3100mah Ituo cells on "high"



    -Actual: ON LG 3200mah KeepPower (brand new, but been sitting for about 2 months) 2 hrs 23mins. Claimed Run time is verifed. Many factors with using different cells will play a part. So you may get a bit more or a bit less.





    Charge Time: Heavily variable based on cells used and usb charger used to supply power for charging.



    Simple 2 light indication: blue is down to 20% battery life, red is 20% on down.



    Driver UI: Press and hold first goes to "hidden" mode, continue to hold turns off. Simple press turns on and cycles through normal modes.



    2 default modes. One with 3 modes, hidden dim mode (press and hold). Second is 2 modes and hidden flasher.



    Fully programmable in 10% increments for normal modes. Can adjust default modes or program up to 5 of your own, and several choices for the hidden mode. Instructions give a FULL break down of how to do each.



    UI programming takes a bit to sort out all the options, BUT THEY ALL WORK AND WORK WELL.





    Emitters: Claimed are XM-L2 U3 NW. U3 bin isnt something that can be verified obviously. They are XM-L2, output vs run time and tint U3 bin is likely. They are Neutral tint, currently seem to be 3C tint. I will check closer to see if the "pinkish tinge" is there that says 3D tint instead.





    Thermal Path: Good. Emitter pcb is mounted to one large aluminum pill with plenty of thermal paste. This pill is very tightly fitted (but not pressed) into the case, then also held in place by screws. Electronics are mounted seperately behind the pill. Casing does warm up slowly due to mass and surface area. But easy to tell path is good since emitter output decreasing as head warms up isnt visually noticeable.







    Driver: All attention to detail has been covered. No cheap switch or poor assembly. Properly cleaned, epoxy holding inductor, full silicone wire used for both battery contacts and to emitters. Driver has simple but existent thermal path to case via how its mounted.





    ITUO did their homework, they learned from all of us and the execution internally was done very well.





    Beam Shots with some comparison shots and videos coming as weather and time allow.



    Low 20%-





    Medium 50%-





    High 100%-





    As a comparison, here is the Fenix BC30R on Level 4 (High). Its about in line with the Wiz 20 @ 50%, just more spread to the beam:

    Im curious, how is this "way too big"???? Its a dual emitter, self contained light. They don't get any smaller. Combine any dual emitter light with its battery pack and its waaaaaaaay BIGGER

    ^^LOL

    Ok been playing with this a bit more (been constantly raining still). Have the hole programmable driver sorted. Alot to it, but it all works. Been testing it out in the rain (till I get too cold, not exactly warm here) and waterproofing works quite well. Comparing against other lights I am slowly raising my guess on output. 1400ish maybe a bit more.

    PS, a lot of info added to Tech Specs now.

    No, I don't think so. ( A difference in opinion does not a troll make. ) He has too much rep to be a troll ( or troll like ). He just thinks it's big. Sometimes photo's don't do a product justice. I thought the Wiz-1 was big until I had it in my hand. Once in my hand I saw it was smaller than my other 26650 torch ( and much more user friendly ).

    Great review so far tig. I like all the bells and whistles the Wiz20 brings. I'm thinking likely it will produce a beam pattern similar to the Gloworm X2. If someone thought the Wiz-1 provided too narrow a beam pattern they should have no problem with the Wiz20.

    I only see one negative; The Wiz20 doesn't use the GoPro system. That said I'm not sure how easy it will be to re-aim the lamp on the fly. I'm sure the bar mount can be made to adjust but that's not quite the same thing as having a mount with a single adjustable pivot point. Not a major issue but for commuters the ability to easily and quickly adjust the aim of the lamp means a lot when in heavy traffic or if using lower levels of light ( for prolong run time ).

    Tig, does the bottom of the lamp look as though someone might be able to retro-fit the lamp with a GoPro mount if they wanted to? Lot's of aftermarket GoPro mounts.

    Anyway, my take on it is that the Wiz20 is an overall winner. Great touch that ITUO gave it a "Programmable User Interface" and "Neutral LED's", all in a nifty self contained package....Win, Win, Win.

    Oh..tig...almost forgot to ask; I'm wondering if the Wiz20 will run with the USB plug charging. (?) 

    If it does, this might mean someone might be able to hook a USB ( battery pack charger ) to the lamp ( while being used ) to prolong run time. 

    (* I might have answered my own question. I just tried it with my Wiz-1 and it doesn't work.  Not a big deal but would of been nice it it did. Then again, a USB charge pack just contains 18650 cells and since you can switch out cells with the Wiz20 ( or Wiz1 ) it's pretty much the same thing...never mind.. )

    Intriguing. Where's the best place to buy this? I'm looking for a self contained light for my helmet.

    These arent designed out of the box for helmet use just fyi. Would gather buying an aftermarket gopro adapter from vancbiker would open up that option.

    If your in the states, as of right now the only way to order them is via the manufacturer (Ituo) directly.

    Heavy lights don't work so well with GoPro mounts anyway. The extra mass means they tend to pivot around the thumb screw.

    User Review: ITUO Wiz20

    Thanks for the review. How much does it weigh? I've seen bar mount to helmet type adapters before, so I was thinking that would work to get it on a helmet.

    Its posted in the second post.

    @Cat: I'll try to remember to try it tonight. Doubt itll work and as you said, being able to quickly and easily change cells would defeat the purpose anyway.

    After some testing on run time vs capacity used (used Panasonic ncr18650b) driver draws 1.5A avg across 2hrs. At 2:01 is when light went red with the Panasonics, about 3050mah used, 3.29v per cell after resting out of light.

    So calculations and estimates are falling into place pretty well. Ituo's claimed numbers match actual. Lumens at cold start and topped off cells would be right below or at 1500 lumens, would expect to follow cree data based on temp from there. This head dissipates heat INSANELY well. Took 26mins at ambient 70F with no air flow for the head to hit 100f. Seemed to hang out there pretty much only varying a few degrees based on where I would set it down during test. I was chasing my toddler and such during the runtime tests so light was being moved from room to room lol.

    Very pleased to see all claimed specs falling in line with actual.

    Used this for my commute tonight. Was nice to have the high mode coming down the bridge where I spin out my gearing (on any bike, including my fat bike). Its a slightly wider than normal sidewalk with concrete walls on either side. So at those speeds in the dark with street lights illuminating everything except the sidewalk, a light with more power is welcomed. And with the cutoff the front cover creates, I dont piss off drivers while in higher modes.

    I didn't think to bring my camera just to catch a bit of video. I am hoping something in the form of trails will be open Sunday night to give this light a trail test.

    Also, I switched optics to the 25deg. Great mix of even spread and throw. Much less of a hotspot. I'll get beam shots with optics change this weekend.

    Any problems changing the optics? What optics did you use and where did you buy them?

    And speaking of optics; The folks from ITUO told me the other day that they are considering updating the Wiz-1 and 2 with optics. This of course means a whole new redesign if they choose to go that route. They will also be including the "programmable mode UI" into the new lamps as well ( the current press/hold sub-low mode will be done away with though ) Instead you will have 3 programmable steady modes ( 1-10 level programmable output levels ). Flash modes will remain the same ( non-programmable ).

    I noticed the other day on the MTBR light shootout that there are an awful lot of self-contained lamps that are now available. That said the Wiz20 has an advantage at being one of the few to offer neutral tinted LED's. Not to mention ( but I will ) that the Wiz20 is programmable and apparently the optics are removable/replaceable. 

    Looks like I might be able to ride myself on Saturday. Been a while since I've been on a bike.

    Yeah they are asking around and doing grass roots style research which I like. Going to optics will help make the wiz1 &2 more compact and flexible. My wiz 20 is on its way

    I told them the 18650 version to leave on reflector since its fitting for a helmet light, any optic is going to make a big spot/loose throw. But the 26650 version is pretty heavy for helmet use, so optics are a good idea there.

    @cat, optics change is STUPID EASY. Since the use the same optics with white holders you can get at fasttech/leddna for dirt cheap (but some of the best optics available) its really east. Pull the front plate screws, gently pull stock optics out, pop new ones in and put the 2 screws back in. Takes like 2 minutes if that.

    Got out tonight for a ride. I got brave:

    My local trail (one 5 mins from home) can be ridden in conditions that close all others due to soil type. Takes alot to make it soft to where its possible to leave ruts. So rideable tonight.

    So knowing that on my 29er the climbs kick my rear, but I can clear them, I went out expecting to be playing hike a bike alot for the steep climbs. Why, cause I took my Mukluk with Nates. And wanted to see how my new Vasque Arrowhead boots felt for riding (loving them btw). So I was running almost as heavy as if geared for snow. 28-31F (temps varied by elevation), no snow. Just wet, greasy, leaf coveted trail.

    Yeap I had to hike-a-bike but less than expected. Only the couple longer yet still steep climbs. The short ones a little more stand and mash but cleared them. Those big a** tires carry moments really well so they actually helped make up for my lower speeds.

    Ok on topic: Wiz20 did AWESOME. 10deg optics would have driven me nuts, but the 25deg optics were perfect. Great tint, my ideal beam pattern. Of course many like the tighter beam that the stock optics will give, my personal preference I dont for a bar light.

    Medium was enough till I started working my way back down. Due to leaf cover I needed the extra power to help pull out the shadows to show where the trail actually was. Did great on medium going in and high on the return side.

    Now there's a plus side to this light that ones like fenix CANT DO. Winter riding matter of cold batteries. The wiz20 has enough heat generation on high mode that in my current temps, my batteries still felt "warm" at the end of the ride. Which mean they stayed well inside optimal temps during the ride. Fenix (and most other mid output self contained lights) generate little heat on max. So they can handle even high temps no problem. Wiz20 will run "hot" by those standards but still much cooler than our little dual emitter lights.

    Neutral tint and generates enough heat to keep batteries from getting too cold makes this the best cold weather light I've seen yet.

    And yes I got video. ;p

    I took a little ride tonight as well ( road set-up ). With temps hovering around 50°F just after dark I thought I might get a short ride in. Damn, must not of had enough clothing on because I still felt cold. I took a couple more beam shots using the Wiz-1 but damn, I still can't seem to get a decent beam shot of the low beam. I guess the phone camera just can't deal with the lower light level. Disappointing because I feel the low setting works very well for general slower speeds. 

    Somewhere I have an old Sony Cyber-shot camera but for the life of me I have no idea where it is. Been years since I last used it. Then again if my memory serves me, it too didn't work well in cold weather. 

    So far I haven't noticed any problems with the Wiz-1 riding in the cold. On the other hand the cold definitely had an effect on my cheap UF 501-B drop-in torch I was using on the helmet. Of course could of just been the battery was low.

    OK so video from last night is no good, lol. I was fighting with the high moisture content in the air, had to switch camera cases (one mounted on the bike immediately fogged up when i opened it to put camera in). And in the rush to switch, I didnt get the camera close enough tot he stem to actually point truly forward...

    That said, the video did reveal something Im not fond of:
    PWM frequency is REALLY LOW. Like KD2 kind of low. Medium mode on the Wiz20 has very noticeable PWM on camera on the edges of the beam. Needs improvement. Wont show as bad once i redo the video with camera actually pointing forward, but I don't like seeing it that strongly. I do expect some hint of it in low mode, but not medium. Especially in such a excellent light.

    Also, having tested a few optics beam patterns against my other lights (matching optics each time) I noticed the front plate messes with the beam pattern. Not on the 10deg optic, but it does with wider beams. Reason is the way the front plate is machined. The 10deg it seems to cut off the spill a bit, but 25deg you notice it a fair bit more. My thoughts are a "cut off". Which isn't a bad thing, especially for pavement use. Its not a strong cut off, with stock optics you have to know what your looking for to see it unless your looking at the light from a distance in front of it. Since on the bars it would be pointed at a downward angle, it takes a lot of the sting out of looking at the light. Trail use it may or may not bother you. I had wondered why I had to mess with the light position a couple times as Im not used to a cut off.


    Temps around 50 wont effect the cells really, especially in a self contained unit. You might see a mild effect on a separate pack after being out a little while (cells exposed long enough to match outside temps) but thats minimal. Get down close to and below freezing and you start to notice if cells are in a pouch or light head doesnt generate enough heat on a self contained unit.

    Im going to aim for tomorrow to go back out, air is supposed to be much dryer too (and temps above freezing) so I shouldnt have to deal with near as much annoying glare off the leaves and the air itself.
