Quoted from Gnatty: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.
