Okay, for a flashlight, I could possibly see spending $40 for a good one, but a light bulb??? Someone shut those convicts down!!!

I have bought custom light bulbs for more than $60, and unless you have an L.E.D flashlight, all flashings have bulbs in them. Though I agree a flashlight would work fine as an answer.

A light bulb doesn't convert electrons into photons. The high energy state in the filament causes the electrons to jump to higher energy levels, and they then release that energy in the form of a photon.
