A PAR Can consists of a metal housing with a socket for holding a PAR lamp (which includes the light source, lens and reflector). The light produced has a bright oval-shaped center, surrounded by a diffuse area with a soft edge. PAR fixtures are fast to aim, give a good punch of clear light, and are economical to purchase and maintain. Lamps and connectors must be ordered separately unless otherwise noted under specifications. Bright, even light for very short throws. Perfect for tight spaces, accent or display lighting. Fully dimmable. Unlike other PARs, they produce a round beam. Edison plug included. ETL listed.
