Modded an Electro Lumens search and Rescue torch to bring it up to date.
Nice machine work, there 
Is it just the lighting, or is that tailcap a different metal?
The tailcap is Brass.
Nice Steve!
Honking light right there! What are the specs? I mean, if you updated it what emitter and driver did you go with?
See here Dale - Electro Lumens Search and Rescue ST90 upgrade. Completed post 31, 17.2.19
It’s a level blf gt driver and xhp70.2 running 8 amps.
Another satisfying moment for ya Moose, job well done
Thanks pp. The emitter is also dedomed.
I now have the light in shorty mode with 2x18350 Aspire 1100. The battery tube was not quite long enough, so I soldered some pieces of copper to the driver ground ring to effectively lengthen the compartment. Compared to 2x 30Qs it has about 87% of the output or around 5700 lumens. A nice light-weight and compact high-output thrower. 
Can we get an in-hand shot of this beast of a light? :sunglasses:
Last week I put a FET + 7135 Driver - 15mm - MTN-15DDm , with Crescendo firmware, in my On The Road i3!
It improved the usability of the flashlight and also the luminous levels.
Maybe not the “throwiest” light in the category but for a 16340 flashlight with XPL-HI U6-1A, it reaches more than 200m in throw 
House @185m .
Some more photos here.
Today I reworked my number 3 set of X6/X5 lights. The little copper X5 I put a White Flat in and it does 78.75Kcd pulling some 4.5A off an Efest 14500 cell. The X6 I had previously made a spacer for and built a triple with XP-L emitters, so today I pulled the 32mm Noctigon (reflowed onto the sink which was also reflowed into the copper pill) and used a T Pad with 3 SST-40’s. It’s making some 6200 lumens on an 30Q cell, at over 18A tail reading.
I like both, but the little X5 with White Flat is impressive!
I weighed a stock X6 with a cell in it at 6.16 oz, the X6 SS/Cu with a cell weighs a whopping 16.17 oz! After handling the SS/Cu triple the little stock light feels like it has no cell in it… lol
Nice, Dale.
SST40 makes for such a good triple. They have the brighter N5 bin at KD with a lower Vf bin so it should pull even more current and be brighter. Unfortunately I just tested one and it performs identically to the N4 in output and voltage so no performance boost. Not sure if it is just wide tolerances or if they didn’t send me N5s.
Easy B, I got the N5’s from KD… “High Power Luminus SST-40 (Voltage: VH) N5 BC White 6500K ”
I not only used them in this triple but have built up a 7 emitter Supwildfire and will be doing another, this time with copper MCPCBs and a copper heat sink. Also used them in a Q8 which makes more power than some folks here believe it possible to do. All I can do is read the meter, ya know?
Figures you’d be up on the latest SST40s. Your N5s seem to perform pretty well, but I’m pretty confident my N5s are the same as N4s. I’ll ask BanL from KD and maybe order some more.
I got 20 last time and have over-used them… the last project calling for the 40 requires 7 and I only have 6 left. Oops! lol
This weekend I modded my white Emisar D4.
- First I replaced the stock 5000K 3D XPL HI with 4000K 90-CRI LH351D from Mountain Electronics. I … wasn’t impressed. Yes, the output was high-CRI, but it didn’t seem any less green than the SST-20 95 CRI 4000K in one of my other D4. Also, as expected the output was noticeably more floody. But that meant I needed to turn the light up higher to illuminate things. I guess I just prefer a little more throw.
- Then I replaced two of the 4000K LH351D with two 5000K 80-CRI LH351D also from Mountain. Still not impressed. Yes, color temp was a bit cooler, but everything was still green tinted… far more than my XPL HI lights.
- Ended up swapping out all the LH351D for 95CRI 4000K SST-20. It’s still not as beautiful or bright as XPL HI in output, but the reds do pop more with the high CRI.
- So far it looks like my favorite emitter for the D4 is still XPL HI. However, I haven’t tried an Oslon emitter yet. Maybe I should try that.
Also prettied up my white D4 by giving it a metal switch, green and pink aux bezel LEDs and Pobel’s modified Anduril firmware.
I actually do believe you, now that I know KD has 6500K's that look like 5700K's - a fact I wasn't aware of before. Weird the bin is not actually for higher lumens, but lower temp? Strange but it works for me... 
Interesting D4 mod after mod, Firelight2. The XPL HI V2 5D is still my favorite look'n beam, but pretty much all XPL HI's have a consistent looking beam. I'm lik'n Blue's 3500K SST-20's as well, but they are under the BBL.
In the CK vs lumintop race to see who can make an anduril powered tail switch light first it looks like it’s CK 1, LT 0!
In case you’re not impressed cause you don’t know what the folomov 18650s is; the driver is at the tail with the e-switch mounted on it. No wires or secondary tubes connect the head and tail. Power is supplied via a bleed resistor at the head, the LED- output on the driver goes back into the body. This driver could potentially be a drop in replacement for any clicky light to convert to e-switch!
Excellent mod CK!!! Where’s the group-buy on your new driver? I need something like 8 of them!!! :laughing: 
Superb!!
My only worry is heat management. But not every light needs to be a hot rod and there are older ways to manage heat as well…
Nice CK, you did it!! :BEER:
A while back I modded a FandyFire SP03 with 3 SST-40 N4's from KD, and a HQ SRK v3.5A driver in a FET+1 configuration. I used 2.5" 20 AWG wires but extended them with 3" of 26 AWG wires to add resistance. I still hit 8092 lumens at start, 6834 at 30 secs, and 257 kcd (manufacturer lumens) .
Also modded a SupFire L1 with 5 SST-40 N4's from KD. This time I used 3.5" of 25 AWG LED wires, a Q8 driver modded with an Infineon FET. Measurements were a little strange between 35E's and 30Q's. The 35E's actually hit the highest numbers: 12510 lumens at start, 10780 at 30 secs, 134 kcd (manufacturer lumens).
Is 10K possible in a Q8 or any quad using SST-40's? Sure is, based on these #'s with higher resistance LED wires. Springs are bypassed to avoid melting.
