I don't like to go overboard with LED's. Saw 2 Iron Mans sided by side at the NW Pinball Show a couple years ago...one stock and one totally done in LED's. The LED one hurt to look at. I agree with others here that I like to add them selectively. My favorite pins are early Bally SS. I like the LED's behind the back glasses to eliminate heat which can cause then to delaminate. I mostly like the frosted whites (not the retro whites) for playfield illumination and then to experiment with the back glasses to enhance the appearance. The Fathom had the white frosted just in the playfield. Have not done the back glass but I will, and you can see the difference in light between the back glass and the playfield. The Rolling stones has the frosted white in the playfield for general illumination then all LED's in the back glass. Combination of just cheap orange and blues then super bright reds behind "Rolling Stones" and then frosted whites in the center.
