Light diffuser material from Luminit

That would work great for a headlamp , er a headlamp with a reflector that is.

It’s a plastic sheet .25mm (.011”) thick. I pulled off the bezel and stuck it on top of the lens, and put the bezel back on. I’m talking to the sales engineer tomorrow morning, and one of my questions is if there is a “cling” type film available. This company makes all kinds of diffusers, lenses, and holographic films for heads up displays, etc…

very similar to the Zebralight diffuser like in this H600Fd MK III headlamp

Check out how diffused this Acebeam EC50 is in my back yard.

Whoa… cool stuff, hmm imagine if I put it on my TR-J18 with monster driver, extreme flood:D

Thanks for the heads up!

I would love a sample for my headlamps, that is where it really matters to me.

How do you get all your grass to grow white like that? Is it because of the diffuser? :laughing:

What headlamp do you have that you can get the bezel and lens apart?

Robert, would you be willing to send me a couple square inches of the Luminit film?

I’ve got d-c-fix on some lights and would love to compare it to this stuff. I can post some comparison photos.

I use a vinyl cutter and the computer to cut perfectly sized circles. It will cut up to 0.8mm material so it should work with the Luminit film.

If you let me know what sizes you need I can send you some circles of d-c-fix, maximum 3-1/2” diameter.

I can send you a 1.75 x 2.25 piece. Will that work? You have to promise to post your “before and after” results here. Deal?

Thanks for the DC fix offer, but I’m fine with this. If I end up buying a bunch of sheets of this, I might hit you up to cut them. Had a nice discussion with the engineer today, and waiting on pricing. Hopefully it won’t be too horribly expensive. The full sheets are 22” x 22”. The way he explained it to me is, these are holographic 2 layer sheets.

PM me your address

Deal! PM sent. :+1:

Thanks for the sample! It arrived today. The holographic nature is interesting… I put it up to just a couple lights to test, but It is far superior to dcfix at first glance. Very smooth and very efficient. It’s pushing me on to get my butt moving on a long outstanding RGBW build i e been working on. Any response to your pricing requests?

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.

do you have a lux tester? im curious to know which diffuser eats up more of the lumens.

Robert generously sent me a sample of Luminit 40-degree film.

The vinyl cutter was able to cut it, but I’ll need to tweak the settings when more film is available.

The 2-1/4” x 1-5/8” sample was just enough to make inserts for four lights.

Here’s an A01, EE X6, S2+ triple, and BLF 348 with Luminit placed behind their lenses.

Perhaps not the first choice of lights for using the film, but most BLF’ers are familiar enough with them to provide a good comparison.

I’ll post beamshots comparing un-modified, d-c-fix, and Luminit in the next couple days.

I’d like to share some beamshots comparing d-c-fix and Luminit 40° film on an EagleEye X6 and a Convoy S2+ triple.

EE X6 is running an MTN17DD-m driver and Nichia 219C emitter.

S2+ triple is running a BLF A6 driver, Nichia 219BT emitters, and Carclo 10507 “narrow spot” optic.

Both lights are running freshly-charged HG2 cells. All photos are taken with the lights at maximum output.

Lights are mounted 38” (96.5 cm) off the ground. The camera is positioned 8” (20 cm) above the lights.

Lights are aimed at the tree in the center of the frame, which is 92 feet (28 meters) away.

Photos were taken about 1.5 hours after sunset.

I’ve included 2-frame comparison .GIFs excluding the d-c-fix photo for folks who have no experience with d-c-fix.

The photoshoot was supervised by a great horned owl, perched high in a tree just over my right shoulder. Yes, really! :slight_smile:

Terrific comparative photos! Thanks for those!

Now wondering how the different angles of Luminit would affect the beam.

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.
Wilkey

Likewise. I’d be happy to pay for a few sheets, pending price info, of course. Thanks for sharing.
