What is an LED?
A light emitting diode (LED) is a semiconductor device that emits visible light when electrical current passes through it, it is a special kind of diode.

What color of light can LED emit?
Most LEDs are monochromatic. Light color is associated with the light wavelength. LEDs made with different semiconductor materials emit lights in different wavelengths. LED light wavelengths range from 400 nanometers (blue) to 800 nanometers (red). The colors of popularly available LEDs in the market are red, orange, amber, yellow, green, blue and white. All of our boards can display up to 90 variations of light and patterns.

Why is the lifespan of an LED measured as lumen depreciation?
The lifespan of an LED is vastly longer than that of incandescent, fluorescent or HID lamp sources, generally can reach 50,000 hours or longer. Although the LED never really burns out, product lifespan is measured by lumen depreciation.
The Illuminating Engineering Society's (IES) current standard for calculating the life of an LED as the point at which the LED reaches 30 percent lumen depreciation.
Remember, a 50,000-hour rating is not equivalent to lamp life rating. LED life is rated where it has reached 30 percent lumen depreciation. At 50,000 hours an LED would still be operating, but at a decreased lumen output.
Based on how long a fixture is illuminated per day, here's what 50,000 works out to:
Hours of Operation: 50,000 hours is:
24 hours a day 5.7 years
18 hours per day 7.4 years
12 hours per day 11.4 years
8 hours per day 17.1 years
