At work we have several 480 volt lights HID we are giving away. SOme
of these can be converted to 110 volts with a new transformer and
low
bay dome. WOuld these be good for my garage/shop? The maintenance
guy
thought they were very bright but put off alot of heat.



Don't modify the lamps, get a step-up transformer.

HID lamps don't generate as much heat per lumen as incandescent lamps,
but probably more than fluorescents. The discharge tubes in HIDs run
bright-yellow hot, though you don't see it until they're quenched,
because the light output of the tube swamps the glow of the envelope.
