No prb. Happy to enable. :)
Guys with non-working lights- in a few weeks when my GAW lights get here I’ll have 9 stock drivers, if you guys need I can supply you replacements then. (I’ll also have a couple spare tiniest10’s left I could sell you if you want modes/adjustable output / 10440 only)
Received my 2 x CW and 2 x NW a few days ago. Took about 15 days to the UK.
very impressed at the obscenely low price. The perfect finish. The tail cap join is impossible to see unless you know exactly where to look.
Head to head with a 9 led cheapie also on alkalines it’s slightly brighter on ceiling bounce and blows the 9 led cheapie away on throw and has nicer tint. Should have bought all CW’s, something like these little lights you just want as bright as possible.
Finally got my lights today.

Rcv'd my two CW pieces today. Stock amps was about 0.98A on a charged TrustFire 10440 @4.10v, lumens was 153 @start and 126 @30 secs, dropped pretty good -- there was no grease or epoxy whatsoever under the MCPCB. Couldn't wait too long - here's my start:
These 10 mm SinkPAD's are great to work with - easy to sand/file down. I did a similar mod to my Tank007 E09. I trimmed the outer edge with a dremel sanding drum. Used 150 sand paper to take down the height from 1.55 mm to ~1.15 mm - sand paper on the bench, rubbing the SinkPAD over it by hand, and used a small round file to make the wire indents deeper. The stock MCPCB is about 1.0 mm thick. Since the pill is brass, I'll just trim out the wire holes to get rid of the edge bumps, sand it down lightly, them I'll probably reflow the SinkPAD to the pill. I'd like to keep the SinkPAD a little thicker than the stock one to help on the heat. Have a few more things to do - little more sanding of the edge to fit easy in, angle file the edges along the wire pads to ensure no grounding, ensure I got enough space for the wire (maybe 24 AWG I'll try), then the biggest problem:
- decide on an emitter, choices: Nichia, XP-G2 warm/neutral, XP-G2 1A, or the new XP-G2 S2 2B
Richard's XP-G2 Q2 7C4 at 90+ CRI looks pretty awesome, available bare.
On 10440's, these little guys get hot really fast, even on 0.80A, and maybe a not-so-great pill mount. Think I'll just leave the stock driver for now, and use thermal/electrical conductive grease around the pill.
Ohhh - be careful with the tailcap off - the edges on the body tube are super sharp. I cut up my hand pretty good when trying to open up the bezel end (stupid me...). I put the tailcap back on, then broke out the $4 rubber coated gloves - then it came off real easy...
Since I got 10 mm XML SinkPAD's, for the 2nd one I think I'll file out the hole in the reflector - it has a flat surface at the bottom, so I think an XM-L2 or XP-L would work pretty good.
received mine two days ago.
nice build but the emitter is way off centre.
will come back with photos.
If you loosen the bezel a bit you can kind if tap it a bit to get it to center.
That or remove the bezel and the o-ring and the glass and reflector will slide out. Reassemble and center the emitter. Just takes a few minutes.
Works. Thanks.
The second ordered…
Oh boy.. Ordered 8 more... They will make a nice gift - very pleased with the 2.
Got 4 today, kind of neutral on these, there OK but nothing special or pretty nice but not that nice, if you know what I mean. These 4 will do, no reorder. The cw looks pretty good but the nw is very yellow.
Edit: After playing with them a little more, I like them better, buy one.
Thanks for the mod info here Tom E. Looking good.
I received 2 more today of the 6 I ordered. So I'm up up to 3 NW received. All have no logo and look and work great. I have 3 CW's on the way. Betting they have a logo give the above. I may try to polish them.
I finished my SF-348 mod from post #434. Don't have all views, but here's some:
Ok - think this mod is almost useless on a good Efest IMR 10440. Here's specifics:
- XP-G2 S2 2C (from FT) on a 10 mm SinkPAD sanded down
- high qual thermal grease under the SinkPAD
- replaced wires with 24 AWG
- NO-OX-ID around the pill, Nyogel on the threads

Mod'ed light with the Efest goes into some sort of over-temp mode, because it starts blinking output in like 20 secs, and the top end of the light is extremely hot. Looks great though for the first 10 secs 
. So, what's going on? Seems like the driver is in DD mode, but not sure if it's something I caused by the mod or not.
Ohh - my amps/lumens measurements are very close to what's listed in the FAQ section on the product page listing on GB (gearbest.com SF-348). Wonder where they got those #'s from...
Nice mod! Thanks for sharing.
Who would use the light more than 10s anyways? :D
Maybe from post #50? ;)
- stupid me, of course!
Shipped…!!!
Gearbest has really slow shipping so it maybe some time.
Just wait a little longer. I didn’t get mine until August 7th. I ordered them on July 7th.
I would like to see this light in a 2AAA form factor. It would be nice with XPG2.
