# How do I turn LED lights into wash lights?

I was wondering what frost is best for spreading the LED beam. We want to hang Chroma-Q Colour Force 72 LED lights vertically behind chloroplast sheets. The beam angle is approximately 23 degrees and we want to diffuse it to approximately 60-70 degrees using a frost. What frost would you recommend?

Thanks,

Don't use frost. Use holographic lenses. I use ETC but there are many other sources.

Thanks for the suggestion. We're trying to save on cost so we're hoping there's a frost that can diffuse the beam fairly well.

Since they are LED and out of view, cutting down a chunk of diffuser from an old florescent light fixture might work. I see dumpsters full of these things as office buildings switch out to more efficient sources.
Unlike frost, which often kills a lot of the output, the diffusers pass a lot of the light.

If you MUST use traditional frost, use a LED flashlight with adjustable beam set to around 23° (Beam angle of the Color Force) and go through the frost section of any swatch-books you may have. MAYBE you will find something that will work good enough. I've used double R104 (in alternate directions) on the similar Colorblaze TRX units to get a soft even wash using them as footlights, there was a noticeable amount of light loss, but it was classical theater so they were never really over 40% intensity anyway.

If you can find the money, the proper way to do this would be with the CHCFBL72: Border Optic for Color Force 72. These spread to 60° according to spec.
