CRX, I am honored that you are my first poster!
I hope that driver hits the streets, that is designed for the S41, and 219C triples and quads. I have a hard time finding drivers that will take the heat! BTW, how did you round out that tailcap, that is badly needed on that light!
Beautiful work man!
Yeah, this will make an excellent light for someone, a lot of hand built work went into it with good components, great pre-thought and some nice techniques mentioned in the text, although it could do with some black on it
What an excellent mod. Thanks for posting it up. :+1:
Very nicely done.
Thanks! Sandpaper is all really. I started with 320, then 600, then 1000, then 1500, then 2000, then rubbing compound, then polish. A lot of elbo grease!
Ha! You are in a blackening streak arenāt youā¦ some of your stuff looks really good with the black. Iāve been following and have some ideas. Right now I am thinking about what product Iām going to get.
Very nice! I actually reflowed XP-L HI v3 3c for my s41s with 17D bistro a few minutes ago! I love the light even more! I have another s41s and now I wanted to use 319ATā¦just wanted more output and those LEDs are cheap!
Very nice build. Iām a huge fan of Dr Jones drivers. His uiās are very well thought out. You have the only h17f+ I have heard of, Im glad you build it a good home worthy of it.
very nice
what eye for detail
Beam shots added in post #2
If anyone has wondered where the sales thread is, it will be another week or two. When polishing up the optics, I must have somehow put a small gouge into one of the tir edges. It shows up as a black line when looking into the light on low. Itās not noticeable in the beam, but itās got to be affecting the output some. So i put in an order for a new optic. I upgraded the shipping so it should only take a week or so. Then I will make a sales thread. In the mean time I will still take offers if someone is interested.
Complications with the optjc(I ruined it) are finally ironed out. I ruined the optic during final assembly, I ordered replacement optic, wait three weeks, get the optic, my wife throws away the optic, I order another optic, wait three weeks, get the optic, optic sits on bench for a number of months, I finally reinstall the optic.
I also took time to repolish the bezel. I didnāt like the way it looked so I went ahead and polished it up like I did the tailcap. Now there is no more stepped bevel to the lens. It is a nice smooth transition with no line. Iām very happy with it.
I will finally put it up for sale in the next few days. Hopefully someone else will appreciate the light enough to bring me a nice reward.
This first picture was taken with flash. It really brought out the shine!
Perfect beam!
Beam with 5deg Luminit lens
The final specs for the light are:
23 AMPS! From one cell. I donāt think this has been done. And around 4000 lumens of high cri 4700k light!
If you are interested in this light, please send me a PM.
Thanks! Hope you enjoyed this build.
excellent work. glad your marketing your services. maybe vinn has some young whipper snaper competition now.
Could you tell some more about the diffusion lens?
In the first post you say about luminix film, in the latest about Luminit lens.
I canāt find luminix, so I guess it was a mistake.
I saw the Luminitās website and still donāt know what do you use, there are both films and lenses, but nothing seems to much what I see hereā¦having no access to datasheets doesnāt help.
Itās Luminitās LSD. The most expensive diffuser Iāve ever use. And for any given thickness theyāre the best. Looks like you have to custom order it. If youāre interested, Luminit can send you a free sample consist of various diffusers in 1ā x 1ā size.

Thanks Clemence, very helpful post. Frankly, Iāve seen the datasheet page, but after being prompted for email, message etc. to download the specs I gave up.
Now I entered some thrash in there and immediately got a file.
Are those films that you need to stick to some base or complete diffusers? If the latter, what is the material? Glass or plastic? I ask because Iād like to know how hard it is to file them to shape.
It would be interesting if some commercial entity offered such diffusers for some common lens sizes. Hint hint.
Though you said they are expensive. Could you share some details?
Iām curious about the thermal regulation. Is there any chance you could get a runtime graph with something like zak.wilsonās ceilingbounce app? Basically, point the light at the phone from a distance, hit start, turn the light on at its highest level. Wait until output has been stable for a few minutes, then hit stop.
I only have one H17F driver, and it takes 8 minutes to regulate to a stable power level. However, itās in a solid copper host which has sufficient thermal mass to handle that, and the light never gets too hot. So itād be a lot more interesting to see results from something with more power and less capacity to deal with heat, like a S41S running at 23 amps.
FWIW, hereās the result on mine: (stepped down ~350 times in ~8 minutes)
Iām mostly curious whether this is as fast as it can step down, or if itās capable of dropping faster.
Original conversation between me and Edward (Luminit)
āā¦The only angle we can offer at this size, 609.6mm x 2400mm, is our LSD 80Ā°. It will cost $600 for one sheet.
In order to be able to place an order and send you a sample, we will need your shipping account number (UPS or FedEx)ā¦.ā
āā¦At this size, we do not have a lower cost option. However, in volume, the price will go down. At 150 meters long, the roll is $6900ā¦.ā
For flashlight application the cost per unit diffusser you get would not be too expensive. I think Pflexpro already selling similar/same stuff.
Iām telling you: this kind of holographic diffusser is awesome! Never seen anything like this before. You can order with/without A/R coated too. Luminitās screen for projector also works like magic.

The Luminit stuff sounds awesome, and Iād love to use it on a few lightsā¦ but Iām okay using cheap stuff. DC-Fix works reasonably well and itās $16 instead of $600, for a similar quantity.
My project was a huge promotional light panel which requires very thin yet uniform light distribution. But even then, we decided to go with cheap MIC panel for only 1/10th Luminitās price. A bit thicker but with more LEDs problem solved.
