I’m subscribed to LED magazine and found this product mentioned. Diffuser film by a company called Luminit and as you can see from their website, they do a lot more than diffuser films.
They sent me a sample. The filter is quite opaque and reminds me of Zebralight diffused lens. Luminit claims “LSDs will achieve between 85% and 92% transmission efficiency”. The thickness of the film is .25mm.
I’d be happy to cut out a small square for anyone who wants to try it. If the feedback is positive, I could possibly buy a few large sheets to cut up into squares and mail out. I have no idea what the pricing is on these sheets, and I’d rather not have people here bombard them with sample requests. The sample looks promising to me. It turns this Acebeam EC 50 into a wall of light.
Here is a few pictures using an Acebeam EC50 GEN II flashlight.
