. You can see two of our lights in the back as well, made from industrial food containers (yep, square tin cans) with 300w R40 lamps.
My first lights were made from the gallon cans I got from the cafeteria.
I would cut the bottoms out of all but one and braze them together. I put 3 together to help narrow the beams.
I then mounted a porcelain socket in the bottom and put a 150 watt spot light in it.
For gels I used the colored report covers I got from the book store. There was no place to buy gels from without a several hour drive.
The brackets were bent aluminum strips.
Hey- you gotta start somewhere
