Believe it or not, there are numerous places online to buy old bulbs for these. This is not the projector in the first pic, but here is a pic of the one I was using before this one, and you see, I put the beam upward, use a washcloth twisted into a donut and secured to place the egg on. You have to be careful not to leave it on there for more than a few seconds, but that's all you need with a high beam like these have.
Whoa, great idea! I was thinking as I was reading about the washcloth...I have a silicone hot pad. I bet you could cut a hole in it and then you wouldn't have to worry about the washcloth burning or getting to hot. You could just leave it there and then get the egg off quick. Maybe...?
Sure, you could do that. And the lens pulls out, too, so it's not like a turtle with its head in the shell. I just don't have a pic of this one extended.
