I was actually going to ask the same thing, is it incandescent? because I can't see the actual bulb but I have one of those 80's lookin type desk lamps you are using too and those bulbs won't work...

Ya know...with all the floro switch talk now days, I wonder how long it will be before those bulbs are a thing of the past. But of course not until dimming florescents are made..lol
