Quoted from CaptainNeo:I use frosted 2smb comet daylight white in all my early SS. They look natural , have great light distribution. I will not use anything else for GI's. Both in backbox and playfield. If 2smb is too bright for you, use 1smb.
Even on skin tones?? I gave up trying to LED my Bally Eight Ball. Every brand/color I tried made Fonzie & Pinky look either yellow/jaundice, or death-blue clammy.
I've stuck with incandescent in most of my backboxes (and PF GI), with sparingly highlights.
