Well, since this is the piclist, why not make an automatic lamp saver dimmer using a 12C508 and a triac ;-) Peter (It's a dimmer that has zero crossing switching and starts from 0% and goes up to 100% in a few cycles - full brightness is attained in 1-2 seconds -- its big brothers save theatre and other big expensive lights every day). -- http://www.piclist.com hint: The PICList is archived three different ways.
