byrdman, welcome to our website and forum. We are glad to have you join us here and we look forward to reading of your adventures and experiences. If too large a wattage bulb is installed in the fixture or if the connections to fixture wires are loose excesive heat will result. There sould be a max size wattage tag or stamping on the fixture. Good luck and keep us posted as to your repair projects too.
