Review: Ultrafire 602C DIY LED Flashlight Host

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.

Thanks very much for the review! Frontpage’d and Sticky’d.

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.

Sorry what batteries you using the 602C?

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. :slight_smile:

Thanks, if you like the small lights this is a nice one!

Updated the origional post with tail cap readings. Dont know why it has taken so long……… OLD!!!

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...

...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 4x7135 driver waiting.
I also happen to have a couple of those SMO reflectors here too. It’s good to have options :slight_smile:
