Reflector Lamps
Reflector lamps (Type R)—a type of incandescent lighting—spread and direct light over specific areas. They are used mainly for floodlighting, spotlighting, and downlighting.
There are two types of reflector lamps: parabolic aluminized and ellipsoidal. Parabolic aluminized reflector lamps (Type PAR) are used for outdoor floodlighting. Ellipsoidal reflector lamps (Type ER) focus light beams about 2 inches (5 centimeters) in front of its enclosure, projecting light down from recessed fixtures. Ellipsoidal reflectors are twice as energy efficient as parabolic reflectors for recessed fixtures.
