LED

LED technology is improving rapidly and many LED products, when used in the right applications, are now being compared to halogen and fluorescent light sources as an energy-saving alternative for commercial and residential applications.

What is an LED?

An LED is a semiconductor device that produces light when an electric current flows through it. The device can be manufactured in a variety of color temperatures. For general illumination purposes, LEDs are then grouped onto an LED array (also called an LED light engine). This array combines multiple LED chips into one complete light source that produces the light output that is equivalent to a bulb.

LED arrays are integrated into a fixture or an LEDi bulb (with a screw-in Edison base).

What are the benefits of using LEDs?

Ensure energy savings: LED light sources have long-lasting, eco-friendly benefits and can minimize energy costs in your home or business by using 15 to 20 watts to replace a 100 watt incandescent.
Reduce maintenance costs: Dim LEDs to extend product lifetime and decrease maintenance costs.
Maximize design options: Transform your visual environment with unique LED colors and dramatic light levels.

Why is LED Control Important?

As LED light sources expand from accent lighting into general illumination, it is more crucial than ever that these sources are controllable.

In the home, consumers expect their light source to act like an incandescent bulb, which means it is fully dimmable to below 1%. Commercially, dimmable lights are critical for both energy savings and increased productivity.

LED products must ensure that their dimming performance meets customer’s expectations and must specify their low-end light level on the specific dimmer that they are compatible with.
