I emailed him this morning, but haven’t heard anything yet. Trying to get a few more samples of the 10,20, and 30° film diffusers. He was supposed to email me pricing today. Going to call him tomorrow.
Was hoping to get this figured out before going on vacation. Feb 9th thru the 19th. Scott (goshdogit) just received a sample and is going to see if he can cut the film on a vinyl cutter.
Robert,
I would be interested in trying some of this material. I first encountered circular holographic diffusers in the flip-up filters for my SureFire lights but those are long gone. Since I very much value highly uniform light for my near-range use, this would be of value to me. Do you anticipate ordering more sheets for splitting? I don’t want to take your stuff if you have more concrete plans.

Goshdogit, awesome comparisons thanks for posting those. I will be back from vacation on the 19th.
A few more samples are being sent to me right now, 10, 20 & 30 degree circular film.
There are also lenses available in the shape of a 20 x 20 inch panels 1.45mm thick, which is the thickness convoy uses on the S2. Pretty sure the C8 is the same thickness. They have to be cut with a cnc machine or something that won’t burn or melt the polycarbonate. The bad news is, these holographic panels cost $300. The good news is, 1 panel would yield approx. 500 lenses at 20.43mm (S2) in diameter. Luminit has offered to custom cut an entire panel, but I don’t know if that includes cleaning, and packaging them in tiny ziplock bags.
The .25mm (.11inch) holographic film panels cost $150, and again would yield approx 500 S2+ size filters.
The beauty of the film is, if you can remove the bezel, then you can take the filter on and off with ease. On the S2+, I’ve been putting the filter inbetween the reflector and the glass lens. On the larger Acebeam EC50, the bezel comes off easy, and I’ve just been putting the filter on top of the glass and screwing the bezel back on.
I will be testing the 10, 20, & 30degree film as soon as I get home. Will send Goshdogit a section of each to post some more comparison pictures.
As it is right now, I believe I will order a few sheets of each, and if people want to buy some at virtually cost, I can cut squares for larger lenses, and maybe have circles cut for more standard sizes like the S2+ and the C8.
These film pieces can be mailed internationally in a letter.
This stuff is really great. I’ve tried taking some beam shots but the only camera I have is on my phone. I couldn’t get them to turn out very good st all:(
I have a couple of lights that I use on the headboard of the bed at night. I would love to see this in a size that would fit the Pineapple and the S2+. I would be in for purchase of either thin material or a real lens for one or both of them.
Good find Robert!
Man, goshdogit those comparison shots you took really do an excellent job showing how well this stuff works. That is a pretty amazing spread of light. Very smooth and even. I just have to figure out which of my lights I want this on but I know I want to try it on a couple. It certainly would be great on a headlamp but I don’t have a headlamp yet. Gotta fix that. Anyway, nice work guys. :+1:
I took my S2+ on vacation with me, and have pretty crappy wifi but managed to get a couple beamshots on the side of the rental chalet, with the 40degree diffuser and one without. The S2+ is a stock neutral white, 6 x 7135.
You can see how the light is diffused and really lights up the roof of the building. It looks like I was a little closer to the building in the first shot, but you get the idea how clean the diffused light is with little loss.
Robert, I am really loving the beam shots I’m seeing from this film. The diffused light is very impressive. The S2+ has a pretty solid diffused beam stock but with that film it’s just incredible. It has a limit to its usefulness by killing throw but for lights intended for up-close work there is nothing better than a wide, floody beam and these beam shots are indicating amazing potential in that category. I’m pretty familiar with the S2+. Can you give me an approximate distance from the chalet these shots were taken? I know you were on vacation so I don’t expect exact measurements, just an estimate. Please send me a PM when you can. I definitely need a sample of this stuff. Great find brother! :+1:
Well, I received the 10°, 20° and 30° circular diffusers in a few days ago. Only problem is the 30° came in a 3mm thick panel instead of film. So I’m waiting on the 30° film. Will upload beamshots off all three using a Convoy C8 XPL HI, and an S2+, to give you an idea of the different levels of diffusion.
Meanwhile, I bought one of the Reylight Pineapples, and stuck a 10° diffuser in between the reflector and the glass. The beam is buttery smooth now, with hardly any loss. Here’s what the non diffused beams look like. I have the ringy reflector, not the upgraded one.
I received the samples from the company. It’s not easy dealing with a company that is used to working with the military and companies like Boeing, then little ol me asking for samples to use in flashlights. The last 4 samples I received came in a Fedex box. Just got a bill from Fedex for $30. I asked them to mail in an envelope or a bubble envelope… lol. Many big companies don’t think twice about mailing things this way. They use Fedex express instead of USPS.
Anyway, in the next few days I will post the 10°, 20° and 30° diffuser photos using a standard S2+ and a C8 XPL-HI, and we can deside which ones best fit our needs. Would like to narrow it down to two.
The 10° really works good to smooth out the beam without disrupting the hot spot too much, where the 40° completely diffuses the hot spot evenly. I’m thinking the 10 and the 30° might serve the purpose really well.
As resourceful as you guys are kind of surprised you are not scavenging holographic diffuser from end devices. I did use a Luminit product in one of my lights to great effect. But as Robert mentioned they are not used to dealing with low lifes like us. I have tons of different diffusers now because I go out and scavenge old flat screen TVs. Almost all the flat screens use holographic diffusers. I have tons of this stuff. I regularly go around looking for TVs thrown away in my neighborhood. At least in my area I find them quite often. The price is right too;)
