Something to throw out that I didn't see above. Do LED lights produce more UV than incandescent? I've been told yes. UV + plastic playfield = bad over time. You would get brittle plastic with prolonged UV exposure. I don't know if LED lights producing UV is fact though. Of course, the LED manufacturers say otherwise because of people asking if they'll get skin cancer. I'd bet those same people don't wear sunscreen in their homes and cars.
