A PAR light bulb is a directional lamp that features a reflector in a parabola shape. The explicit parabolic nature of the reflector allows light to be precisely reflected directly out of the bulb cavity, with less dispersion. PAR light bulbs are a large family of reflector lamps that have an extensive range of applications, e.g. recessed and track lighting, automotive lighting, aircraft landing lights, and theatrical lighting. PAR lamps of small sizes (PAR16, PAR20, PAR30, PAR38) are used to provide general purpose track and recessed lighting for residential use in kitchens, living rooms and dining rooms, as well as for commercial use in restaurants, retail, office, and hospitality applications.
A PAR LED light bulb is an integrated LED lamp that comes with the form factor of legacy incandescent PAR lamps. The integrated lamp includes LED packages of an LED module, a driver capable of providing a constant regulated current supply to the LEDs, optics that regulate luminous flux from the light source, a heat sink which can be independent of or integrated with the housing, and other electrical and mechanical components.
