Light diffuser, anybody cracked it yet?

[atoll]

I am surprised I have not seen a DIY version of the Radion (or others) light diffusers. I have looked on a few forums but have yet to see a successful DIY solution. Anybody know of any and can point me in the right direction?

I se Acrylite Satin Ice material in my blueAcro diffusers. Survives violet light >400nm and works amazingly well. If you use a ton of sub-400 UV you’ll see attenuation.

Phillips uses sanded glass. I assume EcoTech stole the plastic idea from me [emoji6]

Afte close to 30 years of working with some of the best minds in the world , labs , engineers, manufacturers , testing devices, mired shifts , spectral analysts , they all just chose the one that looks the prettiest.

True story.

It’s not new tech. Been doing it in led applications for about 15 years now.

I had this DIY diffuser made from "crushed ice" prismatic acrylic on my Radion gen 1. (You know, this is looong before Ecotech released theirs). It made the light look much more like T5-light. I used it for years, but after upgrading to Radion G3 Pro I didnt put it back on again, since it has better spread.

Smart implementation!

Smart implementation!

The farther the source is from the diffusion , the better the spread.

That’s why my lids are dirty.

That my story anyway.

Cheers guys. I have radions XR30pros gen 3s and was wondering is it worth putting light diffusers on them but here in the UK the radion ones cost £65 about $91 each and I have 3 radions. Seems a lot for a bit of plastic but then we are talking Ecotech.

@atoll I would suggest trying a DIY like in post #6 instead. Pick a simple, inexpensive material like that which you can get at the hardware/home store.

Salty can you buy just the holder for the diffuser materials, like a add on to stage lights

I think we might be on the same road.

I found this in the UK which seems like it may do the job. They will cut it to size and even round the corners off for you. They also drill holes in it if required. I would have to fashion small spacers and longer screws however. Any thoughts?

I have been experimenting with different polycarbonate light diffusers and speak with a plastics supplier that specialises in diffusers. After a few failed attempts I have arrived at what I believe is a near perfect solution. Had more than a few issues getting it right but all seems well now. Here are a few pic's, sorry about the quality there were taken on my phone..

Very polished!

I have been in the rubber and plastics business most of my life. I think you are on to something with using the pressed pattern as a diffuser. You have a link to the material you used? Also any idea on your par loss? 20-30%? range.

I am in the UK so probably not much use to you., I am also started selling them on eBay and have had good feedback. I am currently working on a similar one for the hydra 26s and if there is a demand will expand to the 52s. Suitable screws are holding me up at the moment. I don't have any PAR readings unfortunately but the suppliers confirm there is an 11% light (APR) reduction using their diffusers.

Keep in mind polycarbonate is naturally uv resistant. Might be a reason for the difficulties

From what I understand it very much depends on the thickness of the polycarbonate. I use the thinnest I could find at 3mm which allows more UV than thicker stuff to pass through. Polycarbonate used for say greenhouses is much thicker and reduced UV much more.

HD has a wide selection of stuff like this (as do others, I suspect) if anyone else is looking to experiment:
Ceiling Light Panels & Louvers

I suspect this one is close:
OPTIX Acrylic Micro Prism Glaze 2 ft. x 4 ft. Lay-in Ceiling Light Panel

Less than 1.8mm thick and "great for LED's" even by the manufacturer's word.
