"I feel like the idea would definitely work. My concern would be the safety of the whole thing. Hot water would heat the globe significantly faster and hotter than a lightbulb. There would have to be some sort of temperature regulation mechanism to…"

"That's a smart idea and would be a very fancy setup, although i'm not sure if i would be interested in building something similar as I don't run my lamps when I am not home at all out of fears that my shoddy wiring/construction will…"
