A light source with an integral reflector, usually a silver or aluminum coating on the bulb.
Lamp in which part of the bulb is coated with a reflecting material, either diffuse or specular, so as to control the light, for example: HPL-R, MLR, and 'TL'F lamps.
A light source with a built-in reflecting surface. Sometimes, the term is used to refer specifically to blown bulbs like the R and ER lamps; at other times, it includes all reflectorized lamps like PAR and MR.
A class of incandescent lamps that have an internal reflector to direct the light. Reflector lamps are typically characterized by reflector shapes such as R (reflector), ER (elipsodial reflector), PAR (parabolic aluminized reflector), MR (multi-faceted reflector), and others.
An incandescent, compact fluorescent or HID lamp with a built-in reflecting surface. Incandescent and HID versions are made from a single piece of blow-molded soft or hard glass. CFL versions may be one piece or may be designed so that the inner lamp can be replaced.
