What is PAR LAMP?
PAR is an acronym for parabolic aluminized reflector.
A PAR Lamp which may utilize either an incandescent filament, a halogen filament tube or an HID Arc Tube, is a precision pressed-glass reflector lamp.
PAR lamps rely on both the internal reflector and prisms in the lens for the control of the light beam.
