These units are an excellent price and great spec. even come with a fixed safety bond, rated up to 500 watts. Bought and fitted as part of a local theatre upgrade. I have been specifying these and the long cans for some time now and fit them with 500watt lamps, a much better setup for small halls/theatre as a par 64 used at half brightmess gets a bit orange, these full out at 500watts are the answer. Not all par 56 cans are rated at 500 watts, these are. I have re-discovered par 56 can by using this combination. Try it!
