Step 18: The black light
Originally, I intended to simply buy an inexpensive lamp to hold the black light in the arcade box. Incandescent black-lights, particularly the cheap kind, get extremely hot. I noticed this when I intended to use black-lights for my niece's birthday party, but we had to turn them off because we worried they were too dangerous to use in a party with lots of kids. I wanted to use the heat that the black-light generates to turn the fan that makes the aliens of the arcade move. To do this, I needed to channel, amplify and direct the heat to one side of the fan. I also wanted to use this same light to light up the interior of the arcade.
Two things you need to consider with the black-light. First is that black-lights get very hot and therefore there is a fire risk, especially considering the hot light will essentially be confined in a flammable paper housing. Therefore, it is very important that this light never be left on unattended nor for long periods of time. The next thing to remember is that black-lights are very dim. Your arcade is not going to light-up like a Christmas tree. If you want it to be brighter, you might consider using a standard light-bulb instead.
