Quoted from mrm_4:Having the playfield clear coated is what got me into this debacle. I love incandescent bulbs but I have to go LED because heating up the inserts under clear is guaranteed problems. If you figure out the slow glow effect for LEDs I'll buy at least 3 dozen for my machine!
Then I would have to start a new post. "Frosted or Clear Slow Glow LEDs for old SS games?"
I wouldn't think the heat would be an issue if using 47s. That's what I plan on doing.
