I have 7 SlimPar 56s I am using for an upcoming show on my cyc instead of strip lights. What suggestions do you have for focus besides straight down? Does anyone have photos of something similar?
In my venue our LED PARs are ETC Desire D40s, but ETCOEM's the lenses from somewhere else. I'm sure they'd be happy to sell them to you but you can likely find them for less money elsewhere.
