Step 1: Basic Box
Step 2: Heat Source (also keeps your french fries warm)
I used a total of ten infrared heat lamps that you can purchase at any hardware store. There are four 250 watt bulbs, six 125 watt bulbs, and one 1200 watt patio heater. I had the patio heater already so i incorporated it, but i'm sure I could have used 4 more 250 watt bulbs in its place. This gives me a total of nearly 3000 watts of heating.
The bulbs are mounted with ten porcelin standard 120 volt, 600 watt light fixtures. The kind you find mounted on a rafter in your attic, or in a garage, or basement. They do not have a pull string or switch built into them.
When figuring the placement of the bulbs I had to take into account the thickness of the insulated panels, which I will explain later.
