It takes a normal size, I am sending the old bulb so you can get the exact bulb for it, if you copy the picture and blow it up, the top center looks as if the brains were exposed, that is the bulb.
I didn't realize that the picture doesnt show the bulb, it looks like it has silicone drops on it all over to give the affect of the brains, I plugged it in and the bulb doesnt work.
