That's a great idea. I've found some replacement parts for the fixtures, and used smaller lamps on the three way ones- the lowest setting is great for low, ambient light, and all three on together are adequate. I'm working on replacing the shades, one of which has melted, with something more interesting, replacing the incandescent lamps with LED and just reusing the existing fixtures. They way better made than most anything you'll find to replace them with.
Wherever you go, there you are
