Par lamps are a perfect way to use lighting to illuminate your shows. Par Lamps are available in Medium, Wide and Narrow spread patterns. Depending on the distance of where the light is going to be installed will determine in the spread diameter of the light pattern. Par lights are mostly used for large coverage or either white, color or multi-color applications. PAR is an acronym for parabolic aluminized reflector. A PAR lamp, which may utilize either an incandescent filament, a halogen filament tube or a HID arc tube, is a precision pressed-glass reflector lamp. PAR lamps rely on both the internal reflector and prisms in the lens for control of the light beam.
