A school I work at recently had new lights installed, they are Altman PHX 250w led lekos, some zoom, the rest 26° Barrels.
While focusing some fixtures I noticed color fringing along the edges of the focused beam, possibly due to their led array of the fact that they shine through grating in the ceiling (or possibly due to their short throw, roughly 40-50ft)
Altman makes a soft focus lens accessory for these lights, supposedly a magical 5° diffusion sheet that goes in it's gobo slot. However I wanted to know how else this could be solved, as the manufactured solution is rather expensive for the budget were working with.
Could I simply put some frost gel in a frame at the front of the fixture? Or even in the gobo slot as these fixtures don't get hot?
My primary concern is getting the led array to blend more and be uniform, I'm not too worried about losing intensity as these fixtures are a little overkill for the space.
I'd love to hear your thoughts, anybody have any experience working with fixtures like these?
