LED Screw-in Floodlight Systems

The objective of the lab evaluation project is to assess the incremental energy savings and demand reductions of using LED SDLs over incandescent and fluorescent PAR30 floodlight lamps. Screw-in Directional lighting, or Screw-In Directional Lamps (SDL), refer to lamps with halogen, fluorescent, or light-emitting diode light sources that provide even illumination across a wide area. Short-term durability tests will assess potential immediate defects, failure mechanisms, and feasibility of manufacturer lifetime ratings.

Screw-in Directional lighting, or Screw-In Directional Lamps (SDL), refer to lamps with halogen, fluorescent, or light-emitting diode light sources that provide even illumination across a wide area. Typical halogen and fluorescent SDL lamps have a reflector to direct the light within a certain degree angle. SDL lamps are typically used in applications where the light needs to be directional, such as down lights. LED SDL lamps are designed to replace standard halogen and fluorescent SDL lamps. LED SDL lamps are screw-in replacements for existing fixtures and lighting systems.
