What is LED lighting?

 LED lighting is considered solid-state lighting (SSL). The term solid state refers to lighting that uses semiconductor light-emitting diodes (LEDs), organic light-emitting diodes (OLED), or polymer light-emitting diodes (PLED) as sources of illumination rather than filaments or gases.

Incandescent bulbs use electricity to heat a metal filament until it becomes “white” hot.

 In compact fluorescent (CFL) bulbs, an electric current flows between electrodes at each end of a tube containing gases. This produces ultraviolet (UV) light which is transformed into visible light when it strikes a phosphor coating on the inside of the bulb.

How does LED lighting compare to other types of lighting?

Last longer – Many LED light fixtures have a useful life of 20 years or more, up to 10 times longer than CFL (compact fluorescent) and far longer than typical incandescent.

Are more durable –LED fixtures are often made of metal and plastic rather than glass and do not have a fragile filament, they are less susceptible to damage than incandescent or CFL.

Are mercury-free – Unlike compact fluorescent (CFL), LED are mercury-free, which is safer and better for the environment.

Use less energy – LED fixtures use significantly less electricity than traditional alternatives – often 80-90% less than incandescent bulbs and 25-30% less than CFLs.

Save money – Not only will you spend less on energy since LEDs use less electricity, but you’ll also save the expense and hassle of frequently replacing light bulbs.

Are instantly bright – Unlike many CFLs, which take time to “warm up”, LED fixtures give off their full brightness as soon as they are turned on.

Why does LED lighting cost more?

Turning an LED into a light bulb requires the integration of some pretty sophisticated technologies. Both the manufacturing process and the materials used are more expensive than traditional light fixtures. Although LED fixtures initially cost more to purchase, the added expense is recovered in energy savings and by avoiding replacement costs.
