Review: Ultrafire 602C DIY LED Flashlight Host

Ultra Fire
WF-602C DIY Host

Reviewer’s Overall Rating: 5 of 5

Summary:
Battery: 16340/CR123A
Switch: Reverse Click
Driver size: 17mm
LED Size: 16mm
Lens: Glass
Tailstands: Yes (not perfectly though)
Price Paid: $4.58
From: FASTTECH
Link to light: Ultrafire 602C DIY LED Flashlight Host
Received: January 2013
IPX Rating: Has O-Ring between body and head

FIRST REVIEW SORRY FOR THE RANDOMNESS HOPEFULLY SOME OF IT HELPS

Features:

1. Black Anodized finish
2. All Aluminum body
3. Aluminum reflector (Orange Peel).
4. Nice knurling
5. Smooth threads
6. Clicky switch is nice – not to hard and not to soft
7. The light produces a very floody beam
8. Complete kit except driver, led, and battery

Parts used in the build:

16mm XML T6 1A
17mm Driver – BLF Edition driver same one as used in the A8 build 4 mode with memory
Solar Force protected 16340 (blue/white)

With this combination tail readings
High – 1.8a – 100%
Med – 600ma – 33%
Low – 30ma – 1.6%
Moon – 4ma – .16%

For around $13 you could build yourself one not including batteries.

Overall:

The build was straight forward and pretty simple. I like small lights and carry one in my pocket every day. I am very happy with the light and have not had anything this small before. The modes are wonderful High (turbo), Medium, Low, Moon Low (BLF Edition A8 driver). It gets warm really quick on High/Turbo. Would definitely recommend it for someone that wants a small light that puts out quite a bit of light with the right driver.

Dimensions: As listed on FASTTECH

Depth 22 mm
Height 83 mm
Width 22 mm
Product Weight 31 g

Updated information

Added tailcap readings.

Anodizing on my 602C is tough and I have carried it in my pocket nearly everyday since it has been built (with my cigarette lighter in the same pocket). There are a few small tiny knicks in it. Heck I have got lights brand new out of the package that had more scratches then this on them.

Nice review!  Thanks!  (Though I don't personally care for 16340 lights myself.)  How about tailcap currents?

great review, sounds like a really decent host. Battery size is too small for my very large bag of salvaged 18650s, but it has got me thinking about the equivalent in 18650 size.

I got a 602C from FastTech myself, but mine doesn’t tail-stand at all — the switch cover sticks out a full 2mm, and unevenly at that. Could probably be fixed by shifting the switch inward, but the retaining rings are in tight enough that I wasn’t able to budge them (only able to reach with tweezers).

Did my first flashlight build with it last weekend. XM-L T6-3C, 8*7135 Nanjg 105C (configured to L-M-H), both also from FT. Sweet little pocket rocket…. Multimeter reads 2.795 amps on high with a protected TrustFire Flame 16340; surprisingly, the protection is not tripping.

Thanks matt and Garry.

Will try and get some tailcap reading tonight.
I have the uf2100 which i guess would be it daddy both that and the 602 are really floody lights.
Have been using this light today at work the more I use it the more i like it. If it only had a magnet on the end to hold itself up it might be almost perfect. At work i dont need the high/turbo but have been running it on medium and low. Running it on medium it starts to get warm but not hot.

Thanks again

Sweet ralf nice build congrats on the first build.

How did the driver fit? Mine fit pretty loose definitely not a press fit. Solder secured it though.

Everyone that has this size of battery and likes small lights ought to get one of these.

The driver was a tight press-fit on mine.

Ok thanks for the info. Only tried the A8 driver maybe it is just a little undersized.

Nice review! Gotta get one now. I ordered a few of these https://www.fasttech.com/p/1198400, probably to sell/giveaway in a build.

those look really tidy Tom, you’ll have to let us know what they’re like when they arrive. Should make for a straightforward and simple build.

Thanks

Saw that on site first then its little brother came out and with it having a low price pulled the trigger immediately! That host kind of reminds me of the TR-801 which i recently obtained from a member on here. Let us know how it turns out when you get’er done.

 I built 3 so far, best one did about 800 lumens, worse did about 760 or so - U3 1C, staying w/2.8A Nanjg, but custom programmed.  The Ft U3 1C's are all over the place from cool white to neutral it seems like. Sold one, gave another to my brother-n-law. Really like them - the pill is brass and pretty chunky - was able to get 1 copper disc in there. Got parts for 1 more, now debating whether to wait on 16mm SinkPAD's. It's a quality host, though do like the black finish and grip of the XIAOZHI a little better. Had some usual issues - added thin O-ring under the boot switch so it tailstands without rocking, had to drill adjustment holes in the brass ring for loosening/tightening, nothing major.

Since I have built this I have not stopped carrying this light! I only had a T6 1a tint when I put this in, its ok but I think that I want to put a 2B xml in it. They dont sale the U2 2B at FT in the 16mm size but going to reflow and see how that works out.

So the U3’s are random tints? I was thinking about putting the U3’s and my 3T6 or SRK guess I wont try that.

I still recommend this light for anyone that like 16340’s and small bright lights!

Yes - the FT U3's vary - others reported the same thing. I did those 3 builds at the same time and compared the beams side by side, and same hosts, driver, etc., and one was definitely whiter than the other 2. I still got a few FT U3's and hoping to get a chance to upgrade a 3 LED light with them anyway.

 I gotta order one of these hosts in the next FT order.

I guess even with the tints being a little different they are pumping out the lumens so i would guess the bins are not to bad off then. I got a friend that wants one, will have to get one soon myself.

What batteries are running in yours? I am using the solar force protected blue and whites.

In the SRK? I got the FF UV-S5 and am using TF 3000's right now, but tested with Pana's. I also have a FF STL-V6 triple emitter, 2 18650's, and use Pana protected in that for pretty good output.

 Oh, don't have the host yet but when I do, I'd probably use the unprotected DLG's I got from KumaBear. Not sure if he's taking orders yet - still haven't gotten a confirmation from him on an old order, because I'd order a couple more. Think'n if I order the host in the next few days, maybe, just maybe, the 16mm SinkPAD's would be timed close for delivery from Nitro with this host from FT, because it may make one awesome pocket rocket with an XM-L2 or U3 on a SinkPAD! If I go with a SinkPAD though, probably need something with IMR or IMR like high current capability - have to look around.

Dang that would be a little pocket rocket U3 with one if your stacked drivers! Wonder if 800 lumens could fly out of this thing. It might put out so much light the it can hover by itself! Lol

I missed this one. Nice review apt323! I like the size of CR123 hosts. This one is now on my wishlist. Smile

I've just used the same host to build a light using an XM-L U2 and Nanjg 101-AK w/ 4x 7135 chips at 1400mA; I think this is a good driver for this size of light; good brightness but not running the compact cells ragged like a higher-power driver.

My issue with the light was the reflector; it's a sloppy/loose fit that makes it very difficult to center properly on the emitter. Digging through my Pat. Pend. "Box o' Parts" tm produced a couple of these DX reflectors that were too wide for my F20 mod due to the outside threads...

http://dx.com/p/18-5mm-textured-aluminum-reflector-5951

http://dx.com/p/18-5mm-smooth-aluminum-reflector-5960

...but which fit perfectly into the 602C host, MUCH better than the original reflector. These also work perfectly with the XM-L emitter. Now I have the option of interchangeable SMO/OP reflectors in this host.

I ordered this host today. I have a T6 3C emitter and a 4×7135 driver waiting.
I also happen to have a couple of those SMO reflectors here too. It’s good to have options Smile

Keltex – that sounds like a sweet setup – Did you use the smooth reflector, if so how does it look? I remember those reflectors from your F20 build. I have gave away two of my F20’s one was stock with xre to a member on here and the other to my buddy and it had a xpg2 4c in it. Still have the F20 with the nichia in it though.

relic – thats going to be a sweet setup also! – was thinking of either replacing my XML 1A with another tint it is just to grey/blue or either buying another one (a buddy wants a 602c with battery and charger setup). Maybe a XML U2 2C like they got at FT but the dang thing only comes in 20mm. Guess could reflow it to another board but have not tried it on anything but cheap/used expendable leds…. Guess I need to get over the fear of failure and get’er done. I did destroy a brand new green XPE already…. :_(

I have carried this all but a few days since it has been built and dont really have any scratches or nicks or anything the anodizing is quite nice an tough! I carried my L2M for a couple of months and the anodizing was coming off already!

I think the XM-L U2 2C is what is in the EA4W. It’s a NW without being too yellow. The 3C tint is nice too, but now you’ve got me thinking about that U2 2C… hmm. I already have a CR123 sized host with 3c tint… I have an order in with FT right now, maybe I can add that in. Wink
Edit: not seeing a U2 in a 2C tint at FT…
Edit: nevermind, found it.
Good news about the ano being tough too.

I started with the SMO but replaced it with the OP, and I will probably leave it that way for a while. The light's not a thrower in any way, so it really doesn't benefit from the SMO IMO. I like the OP reflector's smoother/floodier beam; it seems better suited for a compact EDC. I finally found the correct directions for jumpering the legs to make the 101AK driver 3-mode and this light is great now. A pocket clip would be a definite improvement though. The F20 will probably continue to be my EDC just because of the pocket clip.

I ordered 3 of these hosts from FT and got them in today…they’re pretty nice! not sure on the anodizing yet but looks/feels nice. my only complaint is that the pill is paper thin. the reflector is a little loose so I wrapped it in some aluminum tape that I use for p60s and the body heats up within seconds.

I am running an xm-l2 U2 with a nanjg 105c at 2.8A. I realize that this is way overkill but don’t plan to use it on high for more than a few seconds here or there…medium seems fine. these things are beasts! when I first finished it I stuck in a protected tf flame 16340 and it wouldn’t light on high..that’s when I knew it was serious. I put in an aw imr 16340 and its a blinding wall of light! it’s just a bit longer and wider than my eagletac d25c clicky..perfect edc size. this thing is nuts I might have to order a few more as cheap as they are

Nice build. Thats a pocket rocket at 2.8a!

I ordered a couple of those 4 mode version nanjg drivers from IO and those would be perfect in these small hosts. Turbo – medium – low – 20ma low.
