That last post is similar to my lost candler that I found lol. I found a small light base (was made for displaying fancy painted bulbs for christmas) but any light base that sits flat would work if its small. I put this inside of a coffee can, ran the cord out thru a hole in the top of the can, and covered the whole top and sides of the can with black electric tape. I then put a small hole in the center of the top of the can, that my egg sits on. Works wonderful but was considering the flashlight method for when I want to candle a broody's eggs...I dont have electric in my coops.
