What is the cost of solid-state lighting today? How does the cost compare with incandescent and fluorescent lamps?
The life ownership cost of lighting is the cost of lighting over the lifetime of the light source, including both the purchase and operating costs of lighting. Current white LEDs have life ownership costs roughly 2x higher than incandescent lamps, and roughly 10x higher than fluorescent lamps. Part of the promise of solid-state lighting is its potentially longer lifetimes and greater efficiencies, which could ultimately lead to life ownership costs that are 1/10 and 1/2 those of incandescent and fluorescent lighting, respectively. A more detailed discussion of life ownership cost can be found in the recent U.S.-Department-of-Energy-sponsored OIDA Roadmap entitled ” Light Emitting Diodes (LEDs) for General Illumination Update 2002″ (pdf – 1.7MB).
