Dropping the voltage on incandescent lamps by 10% increases the life by a lot. Doing all of the above make it about as foolproof as possible. I power up my antique Xmas lights up by slowly increasing the voltage with a variac. Having a box that does all of that for me would be nice. Note that I'm using parallel wired festoons connected to a big 12V exterior lighting transformer and light dimmers are right out because of the inductive load. There IS such a dimmer but I haven't seen any for sale for a long time. I actually have one in a portable neon sign transformer but I don't care to remove it.
