    CAt User Review: ITUO Wiz 1 : ( Self-Contained 26650 Li-ion Bike Lamp / Torch )

    Pre-ramble ( )

    Sometimes it's hard to start on a review of a product. Especially when you first thought right from the git-go that you weren't going to like it, only to find that when you finally got it that it was much better than you originally thought..whew! The Wiz 1 is indeed a very interesting product. Although I've only had it a couple days I am finding it very hard "not to like". Someone might say, "Yeah, it's just a torch", and yes they are right. The thing is, "Not all torches are created equal" and as torches go ( of which I own at least a dozen or so ) The Wiz 1 stands out from the crowd but alas I am getting ahead of myself. I don't want to heap too much praise on it till I've had more time to play with it...and so it goes.

    Initial Evaluation:

    The Wiz 1 is a self contained bike lamp / torch designed specifically for bikes. Since it is using a single 26650 Li-ion cell to power the emitter my initial thought was that it was going to be humongously big and stick out like a sore thumb sitting on the bars. I was very surprised that when I got it the first thing I was struck by was it's size. It was nowhere near as big as I thought it was going to be. Strange how sometimes photos on the websites sometimes make things look bigger ( or smaller ) than they actually are.

    The torch itself sits very nicely in my hand. Didn't take me long to attach the mount to my ( road ) bike. I had no problems with the mount although it did take me a while to figure out how to get the torch to slide onto the quick-release portion of the mount. The GoPro mount itself I had no problems with. ITUO supposedly sent me an version with an upgraded bar mount. In the kit they sent me I noticed a couple extra rubber pieces but I had no problem mounting the lamp on either my road set-up ( with larger tapered handlebar ) or my mountain bike bars which are a bit smaller using just the standard rubber pieces that come mounted on the clamp.

    Operation of the lamp is sneakingly familiar. It seems ITUO took some lessons from the Gloworm people and copied their steady beam pattern user interface menu. To people who are not familiar with the GW's the user interface starts off in low, goes to medium, than to high ( and then repeats ). If you press and hold the top button the lamp switches to a "sub-low mode" and then turns off if you continue to hold the button down. In essence this means you have four steady modes> low, medium, high and sub low. Only the first three are in the standard ( single press ) cycle of modes. Sub-low you access by pressing and holding the button down.

    The Wiz 1 also has a flash menu that offers three choices ( or modes ) of flash. In order to access the flash menu you first press the button once to turn the lamp on. The lamp always comes on in the standard low mode. After that you double click the button twice and this enters the flash menu. The opening flash mode is very nice and something that I feel will appeal to a lot of people. Basically it is a standard steady low mode coupled with a slight momentary pulse every second. Very nice for urban environments where you don't need a lot of light but still want people to see you. The other two flash modes are quite bright and sure to get you noticed. One is a series of two quick pulses-a very short pause and then repeats. The last mode is just two bright flashes every second. Personally the last two are quite bright and I don't think I'd ever use them except in full daylight. They are that bright.

    Okay, hope this wets your whistle. I have lots more to say about the Wiz 1. So far I've taken it on two road rides including one I did tonight. Man! tonight it got really cold so I could only ride for so long but I'll talk more about that when I get some more time to write. Time for me to munch out. Hopefully tomorrow I'll have some warmer weather

    Things I plan on talking about concerning the Wiz 1:

    Beam Pattern and tint
    Mounting issues
    Battery run times
    Lamp Output and thermal issues
    Possible Helmet mounting
    ...and a bunch of other stuff...

    A couple photos before I leave. First one, notice the size in comparison to my hand. Not bad for a 26650 cell based torch. Second one, my first ride mounted to my bike. More photos when I get some more time. Oh, almost forgot the disclaimer >

    To whom it may concern; I received the Wiz 1 from ITUO, the manufacturer of the Wiz 1 and 2 for review purposes. I did not pay for the product and yes I get to keep it....

    Feedback from the first ride

    My first really good road ride with the Wiz-1 ( W1) took place on my local roads. Most of the roads near me have a bit of ambient light from street lamps so there weren't too many places where I needed a lot of light. That said I still had a chance to see the attributes of the Wiz-1 in action.

    Not more than a half mile into my ride the first problem I encountered was that the bar clamp started to move when trying to adjust the Gopro mount. I only noticed this because whenever a car would approach from the front I would point the lamp down a bit. The W1 has very good throw so I thought that would be appropriate to re-aim it with head-on traffic. Likely the reason the clamp moved was probably due to the fact that it was a very cool night and that the sudden change in temperature ( from inside to outside ) made it necessary to make an adjustment to the clamp. I stopped and retightened the clamp and from that point on only the GoPro mount would move when called upon. That said the Gopro mount worked very well and held it's place unless I wanted to move it. ( *Note, I did lube the Gopro mount before leaving because it did make some noise whenever I wanted to adjust it. The lube solved this issue )

    The lamp and clamp assembly is very stable when properly mounted. I noticed no vibration or shaking of the lamp. The beam pattern like most torches is a standard conical spot. The reflector has a slight OP ( orange peal ) texture to it so that helps spread the spot out a bit. In comparison the beam pattern is very similar to the original Magicshine MJ-808 ( which I also own ). The spot on the W1 is slightly larger than the 808 though. While the beam pattern of the W1 is not near as wide as say, the Gloworm X2, what it lacks in width it makes up for in intensity and throw.

    The intensity of the lamp itself is very impressive. Even when just using the standard low setting I found I had no problems seeing the road when riding at my normal pace. While the beam pattern is basically a spot I did notice that there is still adequate spill to help see a good portion of the road surface directly in front of the bike. On darkened sections of the road I found I had no problem seeing the entire shoulder. This was on a road with at least 6-7 ft. wide shoulders. While doing this I also compared it to my Gloworm X2. The GWX2 of course has a much wider beam pattern ( which I tend to like ). What I found surprising was that the Wiz-1 was out-throwing the GW when on similar output levels. What the Wiz-1 lacks in a wider/even beam dispersion it makes up for in throw.

    There are of course downsides to the "spot beam pattern" of the Wiz-1. When making sharp turns a wider beam pattern is more useful particularly if the road is very dark. That said I wouldn't consider lack of turn illumination a "deal breaker". A wider beam pattern though does helps illuminate movement off to the sides better. This helps in the spotting of deer and other wildlife before they enter the road way. Of course both of these issues are moot if you also use a helmet light, know the roads you ride on and know when to use the extra lamp.

    While using the Wiz-1 I never felt compelled to use the high setting. The high setting is intensely bright. The medium setting is bright enough for all but the most extreme downhill run. I think that anyone using this lamp on a paved commuter path is going to find that using just the low or sub-low setting is going to be more than adequate for seeing ( keeping in mind that direct on-coming traffic is always a possibility ).

    I'll talk a little more about the high setting and the beam tint with my next post.

    Wiz-1 ; Boost setting

    Tonight I put together a very quick unscientific comparison of three of my most brightest reflector lamps to do an el-quicko lux comparison at roughly 5 meters. My most brightest lamp with the tightest spot, the Xeccon S-12, The ITUO Wiz-1 and the MagicShine MJ-808e. For the record the tightest beam spot is from the S-12, then the 808e and lastly the Wiz-1 with a spot slightly larger than the 808e. Results below. ( Oh, almost forgot to mention; the Wiz 1 battery was not fully charged when I did this test. If I find later that this makes a difference I'll update the post. )


    Lamp.................Reflector diameter....................Lux ( @brightest spot )

    Xeccon S-12..........35mm.................................. ..844 lux

    ITUO Wiz-1............25mm................................. ..478 lux

    MJ-808e.................38mm......................... ..........408 lux

    .............................After about 1 minute.. ( no fan )..............................

    S-12................................................ ...................802 lux

    Wiz-1................................................. .................436 lux

    808E.............................................. .....................365 lux

    Not surprising that the Xeccon S-12 appears brighter since the spot on the S-12 is almost half the size of the Wiz 1's spot. Just remember lux is a measure of intensity at a single point relative to a given distance. In this case 5 meters. Since the beam pattern of the Wiz1 is more dispersed than the S-12 the lux reading is ( of course ) decidedly less. Regardless, it wouldn't surprise me if the Wiz-1 actually has a larger over-all "Lumen" rating...but, that remains to be seen.

    This however does not mean the Wiz by any means is less useful. On the contrary, the wider spot is quite awesome and illuminates quite a large area. More on this aspect as I find time to test it as a helmet light.

    I'm not sure how the Wiz might work as a helmet lamp though. It really depends on how one might try to mount it. Right now I'm looking for a helmet Gopro mount. The biggest question will be, "Will the Gopro helmet mount work on my helmet and have a solid enough base to keep from wobbling"?. That remains to be seen. Luckily the Wiz 1 fits on my helmet without too much modding....small piece of foam and some Velcro and it's fine. Not too heavy either which I find surprising. Still, I'd like to find a Gopro helmet mount that will let me mount the lamp on the the tilting Gopro adapter...that would be cool.

    Oh, a quick note about the beam tint. It's been said to be a neutral white but I'm not so quick to agree. I've compared the Wiz 1 to several types of lamps and torches. The consensus I've arrived to is that the beam tint is some where in the 5500-6000K range. Not quite neutral white and not quite cool white. Call it what you will it is a very nice beam tint and doesn't have the harsh bluish overtones of the "Cool white emitters". Once again the beam tint looks very similar to the Gloworm lamps.

    Okay time to hit the sack. Hope to be able to take a beam shot or two before things get either too cold or too wet. No promises on the when...

    Thanks for posting this, I think this could be the perfect light for my commuter with the medium setting being more than enough light and the user replaceable battery combined with USB charging is exactly what I'm looking for.

    General question, is it easy to source quality 26650 batteries like it is 18650 batteries? The idea of "infinite" run times with spare batteries is very appealing to me.

    I think, the answer is negative. Except for Chinese crap, they're quite rare...

    Ah, yes, I see there are some available from Fenix that should do the trick. Thank you.

    So, where can you actually buy one of these lights? Ituo's website seems informational only, can't find them for sale anywhere.

    I would think so. Fasttech has some of the better Chinese brands and Fasttech is now also listing "Actual capacity" on some of these ( vs. listed capacity ). Not unusual to be able to buy a 26650 cell for cheap that has an actual capacity over 4000mAh. Of course if you want Panasonic those are more expensive and might be harder to source.

    The provided battery that comes with the Wiz 1 looks bigger than most. It is slightly wider than my old Trustfire 26650. If you never used 26650 cells before it is surprising at how well they seem to hold a charge. I don't know what brand of cell ITUO choose for the Wiz 1 but eventually I will be testing it for run time

    ( on a side note; Fasttech sells the "18650 to 26650" battery converters as well so that is always an additional option. )

    Wiz-1 battery

    The only info I have on the Wiz-1 battery is that it is a Chinese made battery. Dimensions are 67mm x 25mm. The listing on the battery says that it is 4500mAh and is protected.

    My old Trustfire 26650 cell is a little smaller. I've checked some of the dimensions of some of the other ( larger capacity ) 26650 cells on Fasttech and some of those are longer and slightly wider. The one listing I found on Amazon for a Panasonic ( 5000mAh ) 26650 cell has almost the same dimensions as the Wiz battery so that is encouraging.

    There are 26650 cells that I've read about that have tested near or over 5000mAh ( @1000ma discharge ( CPF member tested ) and like I've said before Fasttech has tested some of their larger capacity cells. Fasttech didn't list the Panasonic cells though. A slightly longer cell might work if it isn't more than 3mm longer but there is not more than another single mm of width on the battery case to allow a cell with a greater width so keep that in mind.

    I'll try to get a run time test done with the Wiz battery this week. Sorry but I couldn't get any beam photos this weekend but only because it has been so unseasonably COLD! At the moment it is 33F, one degree less than freezing. I can't remember it ever being this cold this early in October where I live. It's suppose to warm up later this week but I'll have to wait and see.

    Works for me quite well, I got a gopro mount from gearbest and replace the straps supplied with by velcro ones, also applied some stick on foam to cope with my 661 helmet shape and VOILA, a very user friendly mount which is very stable and I would think quite universal, here are some photos.

    I know some people dislike the GOPRO system, I don have a gopro but still like bracketing system!

    Glad to see it can work with a helmet. I've tried mine on the helmet ( without Gopro mount ) it actually works very well considering the size. The battery holder is pretty lite so really the only thing making it more heavier than a regular 18650 torch is the 26650 battery itself.

    I'll eventually get a Gopro helmet mount and try it just for the heck of it but likely I'm going to mount it more towards the center of the helmet to to make it more balanced.

    One of the lamps I've compared the Wiz-1 to has been the Xeccon 1211. Both it seems have the same basic beam pattern with the W1 being perhaps slighter wider and with a brighter spill.

    A while back when I was testing the Xeccon 1211 I was a bit disappointed that the beam didn't seem to be as intense when in actual use. It seems when it warmed up the intensity would drop so I'm going to have to use the Wiz-1 on high a bit to see how it might compare ( just to be fair ). I'm hoping the auto-power down feature of the Wiz doesn't kick in too soon or it might not be as useful on high. The up side though is that the medium mode is pretty good by itself. ( Xeccon 1211 doesn't have a medium mode, only H-L. )

    I have a couple beam pics of the Wiz-1 but sadly they didn't turn out so good as I had nothing to lean against to steady the camera. I'll post them anyway ( when I get a chance ) because no telling when I'll find a better place to get better photos.

    Wiz-1 beam shots ( poor quality but better than nothing )

    I've really been struggling to try to get good beam shots in of the Wiz-1. The weather, seasonal changes and my job responsibilities are not helping me any. I thought I was going to get a chance tonight with some reasonable temperatures but just before I decided to go out the temp drop almost 20 in just a couple hours. Last time I went out I was over dressed. This time I went out expecting temps near 60F only to find that it dropped down to 43F which really pissed me off. I went out anyway but damn I was cold. Sadly the paved paths I was using for the beam shots were all but covered with fallen leaves. ...That too was not exactly what I wanted. Almost felt like I was riding single track only I was on my road set-up. I had to be real careful not to run off the paved trail with my skinny tires. That took a lot of fun out of it but I think I managed to get some half-decent photos.

    Photo details: Photos taken with Droid Maxx, no tripod used. First marker ( plastic cup ) is at 50ft, second at 75ft. ...third is at 150 ft.

    1) photo one; Low mode, camera has problem with lower light levels, the light is not green. Low can still reach close to the 75 ft. mark.

    2) Photo two; medium mode, light easily reaches beyond 75ft. Notice how well you can see close to the bike ( even with all the leaf cover )

    3) Photo three; Medium mode again this time at 2X mag. At this setting you can see the third cup at 150ft. ( even though the leaf cover hampers the reflective light that would normally be present to help illuminate things in the distance.

    4) Photo four; High mode at 2X mag. Although my hands are shaking a bit you can still tell how well the lamp throws. Clearly to 150 ft. and lights up a nice swath of trail with the spill.

    When I rode back I had to use the lamp in medium mode just so I wouldn't run off the paved trail because of the leaf cover. Normally low is good enough if no leaves are present. It bothers me that my phone camera can't really represent how well the low is. I might search for another photo app. I need one with a night setting.

    The Wiz1/2 lights will soon be available at BrightBikeLights.com - from next week (November 16th is the target date). There are some extensive reviews on this forum - my input is to say that I've tested them 'hands on' commuting through a busy city and have to say I'm very impressed with the quality, usability and performance of these lights. I only stock lights I'm impressed with - these certainly hit the spot.

    Ah, that's great news. Nice to know that someone is going to be a vendor for the Wiz series. Hmm, is this ( BrightBikeLights.com ) a British website? Couldn't help but notice the prices being listed in "".

    Yes, I think we agree, the quality is very nice. The Wiz-1 certainly is a first class commuter light. The 26650 cell option gives it a nice advantage over some of the better single 18650 cell self-contained based lamps. If you have a longer commute the Wiz-1 can offer some decent run times without the need to switch out the battery. I plan to do some run time tests real soon.

    When I contacted Ituo about a purchase, they mentioned (at that time anyway) they did not have a US vendor set up, so in the states we'd have to direct buy from them. They weren't planning on selling direct to consumer, so I assume that the plan is to make them available through a third party site eventually. For anyone who wants one though, they are quite accommodating.

    I know this is not helping the US riders but here in the UK I have been informed that we have a distributor brightbikelights.com.
    An update on my review in another thread follows:

    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). Works well for me!

    Would be nice if there was a North American vendor otherwise the shipping cost from the U.K. might make a purchase cost prohibited. That would depend though on the final cost of the product plus shipping.

    I'm curious, does the Wiz2 ( 18650 cell version ) have the same output intensity as the Wiz-1 on the same modes?

    About the W1 / W2 combo you mention; I've tried using the "steady plus pulse" mode ( on the bars ) while riding after dark. As the English would say, "Not my cup of tea". I would use it though before complete darkness, otherwise the reflection of the pulse-flash off the road surface would annoy me. Personally, for road use I prefer using a mini-flasher ( 60 lumen ) mounted to my front fork and pointed slightly up so the output doesn't reflect off the road surface. My main bar lamp I use in standard steady modes.

    Hi Cat I would think it is just a matter of time until they fine someone in the US, buying abroad often make it expensive due to shipping cost, when I was looking to buy my Gloworm X2,I looked at some of the US giants, but once the shipping was added, this was not worth doing, specially with custom import fee lurking on the deal. This is not my place to give that advise, but if you can not get it direct from your country, get in touch direct with the manufacturer.

    Regarding the steady pulse mode and my ridding choices I should have made this a little clearer. This choices are only for road condition while commuting to and from work. The conditions are road with street lighting, I would not use it on unlit roads as the change between steady and pulse is quite bright and would not be comfortable to ride. This is a good town mode.

    Regarding the WIZ2, the function and modes ect are identical as the head are the same with a different name (actually my sample WIZ2 had the head marked with WIZ1 logo, I have checked with ITUO, and the electronics are the same)The only difference is the run time, light do behave the same just every thing happen quicker except for the 7mn step down which is unchanged. I do prefer the wiz1 due to its 26550 battery, run time and discharge curve is so much better, I just use the WIZ2 on my helmet as it is a little lighter and I am lucky to have the choice.

    ^^^....interesting. I was going to do a run time test on high but I see you beat me to it. Looks like after auto-power down kicks in it drops to about ~650-600 lumen. That is still a lot of light! Looks like the Wiz-1 runs at that level for 2 hours and 45 minutes with the 26650 wiz cell. Twenty-five minutes more and output drops to near 200 lumen. After that it still runs quite a while at lower levels.

    I'll probably still do a test starting at the mid-mode and see how long it will run at that level. I'm guessing over 3.5 hrs before it starts to dim noticeably but we'll see.

    Oh, on a side note I think I figured out how to adjust the light exposure on my Android phone. Can't wait to see if it's going to make a difference but it should. I won't know for sure till I try it outside. Cold as cat-crap outside right now.

    I was going to buy a couple Cateye Volt 800 (1 for helmet, one for bar) - then stumbled across this. I was put off at the $50 single sell batteries by Cateye so I'm really interested in the WIZ series now. I see it's now marketed as 800 instead of 900 and the screenshots a user uploaded to amazon say (Constant 800) - does this mean it doesn't go down by 30% after 7 minutes? If so, I'm sold on this light.

    If helmet mounting, does it make sense to go to the lighter WIZ2? I was thinking of buying 2 of the WIZ1, and then just buy some 18650 cells with a two dollar adapter...maybe half a gram weight penelty and the option to run either batter (lighter battery in the helmet). I'd assume 50 grams in battery can be felt after a 3 hour trail ride.

    With the smaller battery I think I'd be looking at 150grams + helmet mount, compared to 135 + mount for the Cateye.


    --Sorry for cross posting this as I see two user reviews on mtbr. I'm mainly trying to find out if there is still a big drop in light after 7 minutes, as I'm using the lights for rugged fast single track.

    No there isn't a big drop like before, much more constant now.

    I tend not to run high for more than a couple minutes with any lamp I use myself. The run-time test was done by another reviewer. I have a hard time believing that their was a 30% drop after just 7 minutes unless a fan was not used during the test to cool the lamp. Still the reviewer shows a drop but afterward the lamp maintains a fairly stable output for 115 minutes ( with 26650 cell ).

    When I get chance I'll do a quicky runtime test and see if indeed there is a noticeable drop after 7 minutes. Keep in mind that it is entirely normal for there to be a slight drop as the emitter heats up. Should be more like 10-15% though.

    The old ones there is a drop, the new versions run pretty constant. To do that is why they lowered the lumens. Had to to keep output more constant.
