These specialized illumination devices feature a reflective coating applied to a portion of the bulb, typically the tip. This reflective surface redirects light, minimizing glare and concentrating illumination in a specific direction. They find use in applications where directed lighting is desirable, such as in recessed fixtures and pendant lights.
The utilization of this lighting technology offers several advantages. By controlling the light distribution, it reduces wasted light and can improve energy efficiency. Historically, these bulbs provided a method for creating focused light sources before the widespread availability of sophisticated reflector designs in lighting fixtures. Their continued use is based on their aesthetic qualities and functional benefits in specific lighting applications.
