Personally I am nearly always against colored leds in EM games. At some shows you'll see an EM clown pule game or two with leds. Can't stand it. Throwing in all frosted warm white is pretty dang close and when walking by rows on EMs at shows isn't always easy to tell, imo, which has leds at first glance. Frequently you can tell because it is the game without burnt out bulbs
Quoted from Drumdink:
If you have more than one pin, LED all bulbs. It keeps the heat down in the room.
A little trick...purchase inexpensive clear LED's and use colored sharpies to get them any color you need. Always hate when I order the wrong colors. I've used this method a few times--color the bulbs as needed and only stock good quality clear (ablaze) bulbs!
Sharpies fade pretty harshly over time. How long does this usually successfully last for you?
