I took apart 2 different kinds. Items and approximate weight:

Shiny aluminum reflector- 1.5lbs
dirty reflector- same, but has thick glass inside it also.
big transformer- 15.5 lbs
smaller transformer- 12 lbs
dirty cast aluminum - 5 lbs
not sure what white housing is. Could it also be painted cast aluminum? It is not magnetic. It weighs 3 lbs

The wires are copper, but many thin wires individually insulated inside the whole plug. Is this worth stripping? What about the transformers? If I take a cut off wheel to one side I should be able to pop out the windings. What is the body of the transformer made from? Sorry about all of the newbie questions, but I'm already having fun. There's not a time limit on this so it can be something to do when Im not at work to make a bit of side money.
