Quoted from lapean111:Incandecent all the way, unless you are going to go with that system that allows for the natural look with the LEDs. I think its called OCD or somthing. Otherwise, LEDs look horrible on these games that weren't designed for them, you lose all of the fading effects.
Machines were "designed" with Incondescents because that's all that was available for them. LEDs done in a tasteful way make these machines look way better than with incondescents. Use warm white retrospect for the GI and color matching for the inserts if you want a more traditional look and you will have a brighter gaming experience that will enhance gameplay.
