non ghosting leds still flicker in bally controlled lamps. also, the siegecraft adapters may still leave some sockets flickering, as in power play, etc. it doesnt fix all lamps for sure.
also, a suggestion, use frosted cool white in gi and inserts. keeps the art colors looking as they are supposed to and not to dull not to bright. the frosted cool white from pinball life or marcos look superb.
