    The ITP R01 is something of a unique light – a single-stage light with an integrated 18650 cell, charged by a USB cable. But is that all? Turns out there is more than meets the eye here ... scroll down for more.



    Packaging is fairly basic, in keeping with ITP’s status as the “budget” line of Olight. Inside the cardboard box with plastic insert are the light, simple wrist strap, charging cable, and good quality belt holster. There is no manual card, as the instructions are printed on the back of the package. There were no spare o-rings on my sample.


    From left to right: Energizer CR123A, Klarus NT20, ITP R01, Olight I20, ITP SC2, 4Sevens Quark 123-2, Fenix TK12

    R01: Weight: 122.2g (built-in battery), Length 126.2mm x Width 30.1mm (bezel)

    Overall dimensions are reasonable for this class of light. Weight with battery is also reasonable.



    The tailcap switch is a typical forward clicky, with reasonably good feel. The switch boot cover is continuous with charging cable plug. The light can tailstaind.

    Knurling is not very aggressive at all, even less so than most other Olight/ITP lights. I would describe grip as only “ok”, as the light could be slippery with wet hands.

    Anodizing is good on my sample, no chips in the black finish (HA = type III). Lettering is sharp and clear, bright against the black background.




    Key point here is the charging method. Unfortunately, the light doesn’t use a standard micro-USB connector, but rather a proprietary cable (i.e. similar to many simple cell phone chargers).

    But you need to use their supplied cable for another reason - the charging circuit is part of the USB cable, not the actual light. This is rather unusual; you need to look at the USB base to find out what state you are in during charging.

    UPDATE: CPF user Ray of Light reports the charging cable uses the same chip as the DSD charger. It therefore should charge at 350 mA with proper termination at 4.2 V.



    AW Protected 18650 on the left, AW protected 18500 on the right, in the image above.

    This is where it gets interesting! Turns out the light is not sealed, and you can access the battery. As CPF User Ray of Light points out, it seems to use something close to a 18500 cell (with an extension to reach the positive terminal in the tailcap). But as you will see in my runtime data, the bundled battery performs in keeping with a 2200-2400mAH 18650 cell (scroll down for details).

    Note that the polarity is reversed - the negative battery terminal goes to the head, and the positive goes to the tailcap. The bundled battery only fits the correct way.

    RoL also reports that the R01 will take a standard 18650 (with positive contact terminal nipple), and I can confirm that is true.

    Be careful to observe this unusual polarity arrangement - anything else will fry the R01's circuit. I haven't tried to charge it with a 18650 in there, but RoL reports that doesn't work (and may not be safe thing to try, since it wasn't designed for it). And that's not surprising - the charging system seems to involve a secondary ring around the center top. This likely also explains why flat-top 18650 don't work in the light.

    Note the screw threads are not anodized, so there is no tailcap lock-out.



    The R01 features the Cree XP-E emitter, Q5 output bin. The reflector is smooth, but there are some slight concentric rings in it. I’ve seen this before – I can only assume it helps to reduce artifacts/rings in the beam, without going for full texturing. This will likely produce decent throw.

    Which brings us to the requisite white wall hunting . All lights are on Hi on 18650 (AW Protected where available), about ~0.75 meter from a white wall (with the camera ~1.25 meters back from the wall). Automatic white balance on the camera, to minimize tint differences.













    From now on, all my beamshots will be taken in this standard configuration, to facilitate comparisons.

    As you can see, the R01 is focused for throw, with a very tight hotspot. Actually, it rather reminds me of my classic Streamlight ProPolymer luxeon in some ways. Scroll down to my Summary Tables for more specifics on output.

    UPDATE 12/29/10: I'm going to be updating my 100-yard beamshot thread soon, but here's a sneak preview of a relevant R01 comparison:



    Obviously, the XP-E Q5-equipped R01 can't compare to the XP-G R5-equipped Maelstrom G5, but it gives you a general idea.

    User Interface

    On/off is controlled by the tailcap clicky (press for momentary on, click for lock on). That’s it - the light is single-stage only.

    Charging is automatic when the cable is plugged in. When the USB cable is connected to a computer without the R01 light attached, a small green LED on the base of the USB connector will flash. When connected to the light and charging, the USB cable base lights up a solid bright green. When fully charged, the green light shuts off completely. It took ~7 hours to fully charge a nearly depleted light.

    CPF user Ray of Light reports the charging cable uses the same chip as the DSD charger. It therefore should charge at 350 mA with termination at 4.2V.

    No PWM or Strobe

    There is no PWM or Strobe – the light is single-stage full power.

    Testing Method:

    All my output numbers are relative for my home-made light box setup, a la Quickbeam's flashlightreviews.com method. You can directly compare all my relative output values from different reviews - i.e. an output value of "10" in one graph is the same as "10" in another. All runtimes are done under a cooling fan, except for any extended run Lo/Min modes (i.e. >12 hours) which are done without cooling.

    I have recently devised a method for converting my lightbox relative output values (ROV) to estimated Lumens. See my How to convert Selfbuilt's Lighbox values to Lumens thread for more info.

    Throw/Output Summary Chart:

    Effective November 2010, I have revised my summary tables to match with the current ANSI FL-1 standard for flashlight testing. Please see http://www.sliderule.ca/FL1.htm for a description of the terms used in these tables.



    The max output and throw of the R01 are consistent with its emitter (Q5 output bin) and reflector design.

    See my runtimes below for info on the relative output levels.

    Output/Runtime Comparison:

    UPDATE Dec 21, 2010: Runtimes updated with a standard 2200mAh AW Protected 18650.



    On the bundled battery (orange trace above), output/runtime is what you would expect for a single-stage Q5-equipped light running on an 18650 cell – flat regulation for a good amount of time, followed by slow direct-drive decay.

    Using a standard 2200mAh AW protected 18650 (red trace above), I get a roughly similar runtime pattern. Regulation is a bit tighter, with the light holding max output longer, but the drop-off once the battery falls out of regulation is faster. A higher capacity cell would last longer.

    Potential Issues

    A proprietary USB charging cable needs to be used with the bundled battery (included). Charge indicator status is on the cable, not the light.

    All USB charging methods carry a potential risk to your USB ports. An optional AC charging cable would have been appreciated. But a number of inexpensive USB-AC (or USB-DC) adapters are available, and would likely work.

    Light is single-stage only.

    Preliminary Observations

    The R01 is a distinctive little light. It feels solid and well built. It performed as expected in my testing. I’m glad to see the regulated circuit, with gradual drop-off rather than abrupt shut-down.

    Throw on this light is impressive for the size, with a virtual absence of rings or artifacts. The hotspot is quite tight, but there is a reasonable corona around it. While not as bright as some of the newer lights with higher output bin emitters, I still found the R01 quite bright in its own right.

    I am disappointed to see that a proprietary USB cable is used. I would have preferred a standard micro-USB connector, with charging circuit built into the flashlight (and not the cable). With a proprietary cable, you need to take it with you wherever you go (and if you lose it, you can no longer recharge the light). I suppose this solution helps keep the weight and size down on the flashlight, though.

    Given that you need a proprietary cable, why not simply dispense with USB and go with a regular AC power connector? If you have access to a USB port, you presumably also have access to AC power. I'm guessing this has to do with cost - the R01 is relatively cheap for what you are getting (~$45), and a certified AC cable (plus adapters) would certainly have added to cost.

    On that note, I must admit that I am personally wary of USB-based charging solutions. The charging rate seems acceptable for USB. But a 7 hour charge cycle is a long time, and I always worry about frying a USB port/header with any kind of sustained current. Given how much most of us invest in our computers, the risk of a blown USB port is not something I’m very comfortable with. I recommend you pick up an USB-AC adapter - they are pretty common and inexpensive (i.e. a lot of people use them for iPods, etc.).

    But the key surprise is that you can use your own 18650 in there (as long as it has a positive terminal nipple - flat-tops won't work). But pay attention to the polarity - it is reversed from most lights, with the positive contact going to the tailcap and the negative contact going to the head. This is an unexpected find, and my kudos to CPF user Ray of Light for the insight!

    At the end of the day, I found it a fun a little light to play with. I can see this light being quite popular with general users, given its rechargeable nature. It would also serve well as a duty light for LEO/Security/etc.

    Bottom line, if you want a simple, bright, easy to use, USB-charging light (with option to use a standard 18650), this would fit the bill. The ability to use your own 18650 cells is quite a bonus, in my view (especially considering the low cost). Just pick up a simple USB-AC adapter, and you are good to go.

    Thank you Selfbuit for your excellent review!

    I bought three iTP R01 (and blew one up) since they are very good light for duty work.

    I can add something I found out, regarding the iTP R01.

    The charging is true-terminating. Inside the USB plug, there is the same Li-Ion charger chip used in the DSD charger. It charges at 350 mA with true termination at 4.2 V. It will not start a charge if the battery inside the R01 flashlight is above 4.0 volt. In order to force the charge anyway, you need to unplug the USB and plug it back.

    The included 18650 is in reality a 18500 cell with an extension which includes one additional contact at positive end. It is a battery with three contacts. You can access the battery by unscrewing the tailcap. The battery has a wider diameter at tailcap end (which is positive) to avoid erroneous insertion.

    The iTP R01 works fine with a standard 18650. It has to be fit negative side toward the bezel, and positive end has to have a nipple (no flat-end 18650) in order to contact only the central spring in the tailcap. When a standard 18650 is fitted, it cannot be recharged via the tailcap plug.

    The problem is - if you fit a standard 18650 battery positive first, as in all other 18650 powered lights, it will blew the converter in a fraction of second. This is how I destroyed one of my brand-new iTP R01.

    Regards

    Anthony

    Wow, what a find. Thanks for all the insight Ray of Light! Wow, what a find. Thanks for all the insight Ray of Light!

    I have just amended the review with your key points. The tailcap was stiff in getting off, and I thought originally it had been sealed. Just needed a little more hand force, and it opened right up.

    I can see what you mean about the battery, it only works in reverse orientation (and with a center contact nipple on the positive terminal, toward the tailcap). This is great news though - I will do a 18650 run shortly to compare.

    Thanks again!

    Thanks for the review.

    I agree that the USB charging situation is not ideal. It won't charge from one laptop when the laptop is on battery but it does charge from my eeepc701 netbook on battery, albeit the battery on the eeepc gets down to 20% in less than an hour. It doesn't charge from an unpowered USB hub either. iPad USB converters don't work but the iphone/ipad AC adapter does. I bought these as gifts for people along with an AC USB adapter.

    I think Olight did this to lower production costs. Otherwise they would have to source out PSU's with different AC pins and get them certified in some parts of the world. That doesn't explain why they didn't build the charger into the light with a micro USB port and let people find their own cables.

    Yes, a fair assessment. I should point out that the cost for the unit is relatively cheap (~$45) for what you are getting. This likely factors into why they went the USB-charging route, and not AC (i.e. would driven the cost up). Yes, a fair assessment.

    I forgot to mention it earlier, but I can see that this would indeed be a good duty light. I forgot to mention it earlier, but I can see that this would indeed be a good duty light.

    Simple, easy to use, single high output, good throw, reasonable weight and cost, and you can carry backup rechargeable batteries (18650). Sounds like it meets most of the requirements for LEO/Security, etc.

    Awesome Review!!!!

    I ordered the iTP Solar Traveller Set from BJ, the only difference is the LED in the R01 is the S2 with max 250 Lumens.

    Could I use an AW 18650 with a nipple in it as well??? Just don't charge it in the light also??

    Good to see you like this light cause info was hard to come by on this one.

    BTW.. The model you tested has a Q5 but the title says XP-E R5.

    Yes, I'm sure you can use a "nippled" AW 18650 in the S2-version of the R01. The only difference should be in the emitter.

    And thanks for the typo catch - I just fixed the the title.

    Selfbuilt:

    Have you had an opportunity to test the upgraded S2 model? From my understanding, its good for another 40 lumens over the Q5 model. I just purchased one from Shiningbeam.com, and can send you some pics or impressions to add to this review, IF you find them helpful
