Hey Hudson, those lights look pretty nice!
How hot do they get? I've played with those little LED lights without a heat sink, and MAN, they will start a fire! Just wondering how any fiberglass adjacent to the housing will hold up.
EDIT:
Joe at Vision X says the housing gets to 107C/225F max. Guess that's OK. Just don't touch it until they've had a LONG while to cool down.
