LED (Light Emitting Diode) is a special diode that uses a semiconductor chip to produce light when an electric current is passed through it. LED lights are extremely energy efficient and long lasting making them ideal replacements for traditional power hungry halogen and standard high intensity discharge lights and can save up to 90% on lighting costs.
LEDs began as exciting but expensive electronic components in the sixties, used in handheld calculators and other similar devices. Through research and development, LED technology advanced, became more efficient and less expensive, until it reached its current form. LEDs can now be used for a number of lighting applications and are available across the spectrum of visible, infrared, and ultraviolet light.
With the advancement in technology in recent years, LED lights can be used in a wide range of applications in commercial, industrial and domestic lighting. LED Lights are energy efficient, cost effective, durable and have countless uses and functions.

The useful life of LED lighting products is defined differently than that of other light sources, such as incandescent or compact fluorescent lighting (CFL).LEDs typically do not “burn out” or fail. Instead, they experience ‘lumen depreciation’, wherein the brightness of the LED dims slowly over time.Unlike incandescent bulbs, LED “lifetime” is established on a prediction of when the light output decreases by 30 percent.Long life time stands out as the number one benefit of LED lights. LED bulbs and diodes have an outstanding operational life time expectation of sometimes up to 100.000 hours.This is 11 years of continuous operation, or 22 years of 50% operation. If you leave on the LED fixture for 8h per day it would take around 20 years before you’d have to replace the LED bulb.LED’s are different to standard lighting: They don’t really burn out and stop working like a standard light, moreover the lighting diodes emit lower output levels over a very long period of time and become less bright.
LEDs are incorporated into bulbs and fixtures for general lighting applications. Small in size, LEDs provide unique design opportunities. Some LED bulb solutions may physically resemble familiar light bulbs and better match the appearance of traditional light bulbs. Some LED light fixtures may have LEDs built in as a permanent light source. There are also hybrid approaches where a non-traditional “bulb” or replaceable light source format is used and specially designed for a unique fixture. LEDs offer a tremendous opportunity for innovation in lighting form factors and fit a wider breadth of applications than traditional lighting technologies.
Some of the best potential applications for LEDs are areas where directional light is needed, such as floodlights or spotlights for artwork or architectural elements.
Conventional incandescent and fluorescent lamps emit light in a 270- to 360-degree pattern and require additional reflectors to direct light where it is needed.
Because the light produced by an LED is typically emitted in a single direction, performance is improved by aiming light exactly where it is needed, such as on
merchandise, artwork or tabletops—without losing light inside the fixture.
Fixtures specifically designed for use with LED light sources operate more efficiently and provide better optical control. They may last longer than a replacement lamp because the entire system is designed to work with the LED light source. Because LED fixtures are tested as a complete unit, designers can create systems for optimal performance in the space. Purpose designed fixtures that are DLC listed are available in many styles, including outdoor porch lights, track lighting, pendant lamps and recessed down lights.
