Industrial/Commercial light fixtures
I'd posted about getting these from an electrical contractor. Then KZBell got some at an auction. Then I got to thinking there might be others who get an opportunity for some and knowing scrap potential would help with bidding for them. So here are some weights of various components (didn't get them all).
They were all the same basic size. Some had glass globes and some were plastic (replacement for broken glass?). The aluminum base came to two shapes but about the same weight.
Overall weight was 31.5 pounds:

The globe is either glass or plastic. The glass in the first picture is heavier than the second. I'm guessing the first at 30# and the second at 20#. There is a wire frame around the smaller globe that may be stainless steel but is magnetic so, for me, it goes as Light Iron. Weight - maybe 2#.
The white "base" is cast aluminum and houses the transformer. This half with the transformer weighed 17.5#. The whole transformer weighed 12#.

The "T" core is many sheet of thin iron and weighs 4.5#. Sorry but I didn't get a weight for the "L" shaped iron on the outside of the copper windings.

The copper totaled 3.25#

Hope this helps somebody.
Aluminum Windings in Commercial or Industrial Lights
So I screwed up in a few different ways. The first assuming(yea I know) the windings in my transformers were going to be copper, the ones I had(lights) appeared to have been around for a while and at 21# each I just figured there was no way the were aluminum. Simple scratch test would have told me what it was for sure instead of being an ass and going off the weight. Well after much debate I decided to turn in as CBM today and that's when things went south. Aluminum instead of copper and epoxy holding everything together = at least 1/2 of what I had hoped to bank. Live and learn, still made money, just not as much and I hope someone else reads this and bids and project profit better then I did.
