Not sure how hot they are? Used 12 volts on them to see what they could handle, they got very very very hot! Don't plan on using 12 volts, but you know what they can't handle. Anything over 12 volts. 9 volts? We will see. As I go downstairs, it seems like I should order them (no, I don't have Dr. Frankenstein's scientific equipment. Just things that can lie anywhere). hp I ordered these for micro LEDs so I'll go below for my setup. But for others, this may not be what you want.
