I've been looking for a long time for a blue light bulb to light my selenite lamp that doesn't produce much heat. I've tried a few regular C7 bulbs and the colored ones always burned out within a few days and ours was so hot they were afraid to leave it on for hours. Old-school transparent lightbulbs are good, but boring. I prefer colored ones. When I first received the bulbs I thought they made a mistake and sent me clear bulbs, but once plugged in and turned on they turn a beautiful blue color. I'm so happy!
