An LED is a light-emitting diode, a semiconductor device that emits light when an electric current passes through it, essentially converting electricity into light. When one or more LEDs are combined with an electrical driver and placed in a housing, you have a complete LED light bulb or LED light fixture. In technical terms, you may hear these referred to as LED lamps (instead of light bulbs) or luminaires (instead of light fixtures), respectively.

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, 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.



Last longer – Many LED light bulbs or fixtures have a useful life of 20 years or more, up to 10 times longer than CFL (compact fluorescent) bulbs and far longer than typical incandescents. For example, a LiquidLEDs GLS LED bulb for general household use lasts up to 25 times longer than a traditional incandescent bulb.

Are more durable – LEDs hold up well to jarring, bumping, shock and vibration versus traditional alternatives. And, since LED bulbs are often are made of metal and plastic rather than glass and do not have a fragile filament, they are less susceptible to breakage or damage than incandescent or CFL bulbs.

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

Use less energy – LED light bulbs and 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.

Offer more options for lighting a room – LED lighting is available in a variety of shades of white light, which allows you to customise the look of your space. The light colour is measured on a colour temperature scale (CCT) referred to as Kelvin (K). Kelvin numbers in the 2700-3000k range most closely match the warm colour of incandescent light bulbs. 3500-4100k equates to a “cooler” or “brighter” white light good for kitchens or work spaces. For “bluer” light that is most like natural daylight and helpful for detailed tasks or reading, look for a CCT of 5000-6500K.

Do not burn out – LEDs typically do not “burn out” or fail. Instead, over time, the amount of light produced decreases. Therefore, the “useful life” of an LED lighting product is based on a prediction of when the light output decreases 30 percent versus the time it takes for 50% of a large group of bulbs to burn out, as is the case with traditional incandescent or CFL bulbs.

Do not cause heat build-up – Incandescent bulbs release about 90% of their energy as heat, producing 85 BTU/hour and contributing to heat build-up in a room. In comparison, LED bulbs only produce 3.4 BTU/h!

Are more efficient – LEDs are “directional” light sources which mean they emit light in a specific direction, unlike incandescent and compact fluorescent bulbs which emit light — and heat — in all directions. For this reason, LED lighting uses light and energy more efficiently.

Are instantly bright – Unlike many compact fluorescent (CFL) bulbs, which take the time to “warm up”, LED bulbs and fixtures give off their full brightness as soon as they are turned on.
