PAR 64

Halogen Par 64 lamps are 2 piece construction with an 8 inch diameter and an extended mogul end prong connection.  These lamps are available in narrow spot, medium flood and wide flood beam spreads.  The wattage choice is limited to 500 watt and 1000 watt versions only at 120 volt operating current.  Osram-Sylvania does manufacture an aluminum backed Par 64 with a significantly lighter weight than the standard glass construction.
