As I have six Pins I have only recently thought about changing my incandescent globes to L.E.D.s but only in my later games, The Getaway and Party Zone.
But I will leave my older games with standard globes as it looks the way it was intended.
I no with my Party Zone when it is on for a time there is a bit of heat build up so L.E.D.s for this would be the best thing.
