Thank's for the advice, I've been taught to always wear gloves when working with lamps anyway and power is a no brainer. I was just worried about the substance incase it was somthing I should be worried about.
Hey, I was working on some Stage Beams, and one of the lamps I was replacing broke in half when I took it out of the socket.
I have two questions, Why did it break in half (never seen this happen before) & what is the weird powder coming out of the broken base (looks sort of like chili flakes)...
