What failure(s) cause this?

If you are interested i would be willing to trace the schematic and figure out what failed, then make the repairs and return it to you.

Aluminum is about 1/3 the density of steel, but the mechanical properties are also low such that an aluminum part has to be 3x thicker to have the same strength and load-carrying ability as steel. The heat capacity of aluminum is great which is why it is used for heatsinks, but it’s coefficient of thermal expansion is about twice as much as steel.

Thanks… that is very kind of you. I have to think about it. The light only cost $20.It would be $8 to $10 to ship it to you and get it back to me. There’s a possibility I might just ship it to you and you could fix it and keep it.
