My C8 with dedomed XP-G2 S4 2B did 170 kcd so the White Flat may get you 200. But it must be emphasized that these 1mm2 dies are extremely finicky with centering and focussing, i.e. it pays off if you spend an hour or more on sanding/reaming/cutting centering pieces, however insignificant such a tiny piece of plastic seems to be. And even then if a corner of the led forces itself a bit into the plastic during tightening of the bezel, you are off again. Also make sure that the reflector is completely free from touching ledwires, even the silicon mantle, it will force the reflector in one direction, a tiny bit is enough to ruin your focus.
I need a little driver advise please.
I’m planning a build with a light that resembles a maglight in form factor (SA police light). I have a roughly 36mm diameter cavity for a driver and I’m going to try run 2/3 18650’s in parallel (with battery tube mods) with a tailswitch, my plan is to set up 3 or 4 separate triple sst20/xpl-hi’s with 10507 or a similar optic all on a press fit copper “shelf”. I’ve already ground an aluminium spacer and press fitted it to give the head more thermal mass (this created a reasonably level shelf, the copper will work as a spacer with more heat sinking so the optic height is correct, hopefully).
What driver could adequately drive 9 xpl-hi’s pretty hard, I’m not too fussed about fancy UI just 4/5 modes with the tail clicky. I guess I’ll use the tailswitch from an S2+ or BLF A6 I have lying around, if it’s up to the task?
It’s a budget build, the host was salvaged a bit so nothing fancy just want it to have reasonable power.
I’ve measured it at just 3m so that might not be completeley fair, but i was just curious to see what kind of results to expect.
I think i can gain a littlebit more by centering and adjusting the height of the gasket.
Is anyone selling 3030 gaskets except INTL-Outdoor ?
EDIT
Some more delicate wet sanding of the gasket and after an hour of centering i get a nearly perfect spot and i measure 20770 Lx at 3 m and 4130 Lx at 7 m which equals 187 kCd at 3 m and 202 kCd at 7 m which is impressive given the low lumen output.
I don’t think so.
If you have one of those 3535 gaskets that fits in the reflector and has a square hole for the led, you can cut new 3030 corners 45 degrees rotated from the 3535 corners. That is how I solved the 3030 led problem a few times already.
Not today but two days ago.
Put Nichia optisolis from Clemence into this tiny stainless stuff
Nice! Is that an array of 4 x Optisolis or one?
It’s a single LED.
The kit was supposed to be used on Jetbeam Mk1 (Jetusolis).
The beam must be ultra-smooth 
I have a few of what I would call “flashlight crumbs” I would like to give to someone in the USA. There are a couple of new drivers I’ve just never used, some medium/large reflectors, and the mcpcb loaded with xhp70.2 that are probly mostly working out of my imalent dx80. Just post your I’ll take it here and then message me your address. All of it it is going together in one box to one person, if that person wants to regift any of it that is their business
Wish I was in the US VoB
I shaved a 3000K LH351D (a LOT, might have even taken a hair off the phosphor on one small section) in a BLF A6.
Hot spot w/ 18350 and stock AR glass at ?? volts:
Low to High:
Ambient = 81.0 Lux, CCT = 2880K (Duv 0.0003)
Color Rendering Index (Ra) = 94.8 [ R9 = 75.4 ]
Ambient = 1391.6 Lux, CCT = 2852K (Duv 0.0005)
Color Rendering Index (Ra) = 94.4 [ R9 = 73.6 ]
Ambient = 5133.7 Lux, CCT = 2937K (Duv 0.0000)
Color Rendering Index (Ra) = 92.7 [ R9 = 68.6 ]
Ambient = 11117.5 Lux, CCT = 2924K (Duv –0.0011)
Color Rendering Index (Ra) = 92.0 [ R9 = 64.8 ]
Here was my old post with the dome on:
That’s awful kind of you, VOB. What kind of drivers are we talking?
I’ll Take It —— Thanks
Reflowed (reflew?) some emitters.
(Note: They are straight off the hotplate, cooling down. Haven’t been cleaned yet! )
4 orange unknown emitters for a “lantern/bonfire simulator” project.
4 219C 5000K to a PL47 board.
And took off 4 XP-L HD (1 broken) emitters, and put on 4 SST-20 4000K
Given my recent journey into reflowing, it has accumulated a lot of loose emitters.
How do you store your bare emitters ?
If I think I will use them again I put them in a small ziplockbag with a label on it, but most end up loose in a boring-parts-box, usually to never be used again. But occasionally I take one out for a build and nowadays I can check tint/CRI before using it.
Not my mod but attention worthy:
Vinh has upped the power of a LEP flashlight, increasing output by about 60%. He may be the first to do so and speak up publicly.

He he is running one of Richards driver’s in it….Regulated VN4
Shipped.
One is a mountain electronics 10mm FET I never got around to using. One is some performer made by a blf member I cant remember. The driver was a big deal at the time I purchased it so maybe chops can post a picture of it and someone will recognize it. The package it came in came from Croatia.
Sounds like a LED4Power driver then
Yep that is it. Looks like I have an old version but it should be a 12 amp capable driver. For sale : LD-2 and LD-M2 driver (Updated) All my comments when ordering are here.
