Reserved for when I get around to adding more mass to the pill and changing out the reflector to an OP one. Currently I’m using the stock reflector which has a big dark hole in the hotspot. I mean it’s real noticable. Very ugly. So I need to swap to a different reflector, maybe a textured one or maybe add some DC Fix to smooth it out.
Thanks for the write up! Gives me a little inspiration for my two L5-S lights.
Cool little light, like a mini-L6.
Nice job with your lighted switch too.
Nice :+1:
Hey mate cool mod. Do any optics fit? You can always make the heatsink to accommodate the optics. If you leave the lense on the optics don’t have to be as wide as the reflector to work.
Are you referring to TIR lenses? I specifically built this light to get away from those. I’m not a fan of their weak spill lighting.
I made a Quad out of mine—the thin aluminum shelf just pops out—I was able to use a quad spacer for the X6 that Nitro was selling way back when—he had also sold a triple spacer for the Ledil Cute optic that is close to the right diameter but would have to be trimmed down in thickness to make a reflector work
If the pill is from brass it would help a lot more if you solder the star to it including filling the gap around the star to the ring,
you may put in there a solid copper wire to fill the gap as good as possible,
the star is the best heat conductor there so its best to optimise its heat path, better than getting the shelf or base of the pill enhanced
The pill is aluminum.
At most it will be on turbo 15 or 20 seconds so I just need mass to control the star temperature.
It may be possible, with Kapton tape for insulating, to get some heat transferred to the reflector if you replace the plastic centering ring with a washer
soldering to aluminum is possible but not easy
Interested
This is just a one off light. Feel free to build one if you want. It blows away anything else on the market.
BTW, I have videos of it in my Sig. I used it to do the Narsil videos.
Just an update, I swapped out the SMO reflector that came with the light to a cut down C8 OP reflector. It really helps to smooth the beam and fill in the donut hole you get with the xhp70.
Have you measured lumen and lux in the light? Please post a beam shot if you can.
I don’t have a light box to measure lumen, I tend to estimate it from the amp draw. Since it pulls 7.8 amps I’d say it’s about 4,500 lumen with fresh cells. These 26350 can get pulled down to 4.1 volt pretty quick. So I’d say 4k lumen to be conservative.
I don’t really care about lux as this is not a thrower. It’s got a nicer hotspot with the OP reflector compared to the SMO. It’s a little dark in the center, but not too noticable. It lights up a big area. Great for walking at night.
I’ll try and get some beam shots tonight.
I look forward to seeing some beam shots from your light. I am not really looking for a ton of throw, but I live out in the country and it is always nice to be able to see a little ways down the road. Sounds like a nice light. I have my U21vn if I need a lot of throw.
Ya, I think many lights don’t use the mass of aluminum reflector efficiently.
Here are some beam shots I just took.
Medium brightness on ground to show beam pattern.
Here is a baseline shot followed by turbo.
I did not have much distance from my backyard so here are some nearby trees.
Nice! I haven’t done anything with mine yet… looking at this thread for inspiration though 
Lexel has informed me that he will be coming out with a boost driver that can run NarsilM in about a month (big time delayed). It should do 2.5-3 amp at 12v and 5-6 amp at 6v.
I plan to build another one of these lights using the xhp70.2 and stock smo reflector.
If Lexel is also using NarsilM v1.2 by then, I hope to set the ramping max to about 2.5A and a double click to 5A max. This should be ideal for my needs.
