Light Emitting Diode (LED) and Compact Fluorescent Lights (CFL) bulbs have recently revolutionized energy-efficient lighting. CFLs are simply miniature versions of full-sized fluorescents that screw into standard lamp sockets. LEDs are small, very efficient solid bulbs, sometimes clustered with diffuser lenses to provide a broad range of applications. LED technology is advancing rapidly, with many new bulb styles available. Initially more expensive than CFLs, LEDs bring more value since they last longer. Also, the price of LED bulbs is going down each year as the manufacturing technology continues to improve.
When considering green buildings, LED lighting provides great benefits which contribute towards green building certification.
Current industry initiatives include the Green Building Power Forum (GBPF) that addresses the occurring convergence of technologies that changes how buildings are powered. These technologies include the rapid growth of distributed generation resources (photovoltaic panels, wind turbines, fuel cells, micro turbines); the emergence of high-efficiency lighting technologies (especially solid-state LED lighting) as well as demand load management of building energy use.
