Par

 A Parcan light is a sealed beam unit that consists of a lamp, reflector and lens. Often referred to as PAR (Parabolic Aluminised Reflector) lights, a Parcan lantern produces a very intense light quality. Therefore, they are particularly suited to producing deep colours or special lighting effects. PAR lamps are available in a range of beam angles, which are created via different levels of diffusion on the front lens. A PAR light creates an elliptical shaped beam, which you can adjust by simply rotating the lamp.
