	Greetings. I recently made curing unit for a dentist. It
	uses 4 300Watt halogen lamps and 4 IR filters. The lamps
	were $20 each and the filters $40.

	The filter looks like ordinary thick, bluish-tint glass that
	just _loves_ to shatter :-( 

	Heat should not be the problem. (I can get a 200Watt 12V lamp)
