GE 1000w PAR64 in use

My dad sent me this photo, him and his team is using this lamp to inspect some metal samples at work. He also told me there used to be spectral lamps, etc. at his company which might still be in a dusty corner so he's going to chase up some leads when he has the time. This lamp looks like a GE 1000w PAR64, in a clamp stand sort of fitting.
