DIY diffusers for LEDs

[Silent]

I have a glass top on my tank. I wish there was an option to replace it with frosted glass and use that as a big diffuser.

Sand it.

I’m located in Mississippi. I’m out of town working now and will be for a couple weeks. I have a stack of full sheets for solar panels I was building. I will have to look into getting a sheet cut into pieces and how difficult that is. I will post here when I get some answers. I’m not sure how difficult it would be to ship a full sheet. I purchased them from a guy in Missouri and drove there to get em. I’ll check into it all. Thx

I'm in North Alabama. If you are sure they aren't tempered, I can cut my own up to 1/4" Just Pm me when you are back in town.

That’s another thing I’ll have to look into. It’s low iron glass but I really never looked into tempered or not. I just figured I would make a green house or more panels with em one day lol. I will pm when I find out more.

I used sand blast paper sticker. It was cheap and really effective. Also the Lux drop off was about 10-20% only fro mthe looks of it.
I purchased the Sticker from a Plastic part store.

I just posted this on the Fresnel Lens thread. I currently have a Bicube 29 with power compacts. I purchased an Ai Prime HD. My plan is to gut it drill a hole in the hood and set the light on top of the hood. The problem is this will make the light too close to the water for a good beam spread. I plan to place a fresnel lens i recover from an old overhead projector inside of the existing light housing. I also have several diffuser elements from an old computer monitor. Fingers crossed. Hope it works.

Bump? Anyone using diy diffusers?

Also any truth to the plastic diffusers? I believe Ecotech diffusers are plastic no?

So imho the biggest problem with adding diffusers to commercial fixtures is that you will end up losing a lot of PAR. Those fixtures have narrow lenses in order to provide as much light as cheaply as possible. Diffusers essentially negate that.

Hello,
Would frosted acrylic work as a diffuser?
