Light emitting diodes (LEDs) have been used for years, primarily in the electronics industry for circuit board mounted indicator lights. Increased performances (brightness), lower production costs, and the availability of a variety of colors have led to the successful use of LEDs in replacing incandescent and flourescent lamps in architectural, commercial and industrial applications.

White LEDs
There are currently two ways to make white light with LEDs. One method mixes multiple wavelengths of different LEDs to make white light (i.e. RGB); allowing the lighting designer to tune the white light to a specific color temperature
The second method uses a blue Indium-Gallium-Nitride (InGaN) LED with a phosphor coating to create white light. This is the method that results in the more commonly seen “white LED.”
High Color Rendering Index (CRI)
CRI is the calculated rendered color of an object. The higher the CRI (based upon a 0-100 scale), the more natural the colors appear. Natural outdoor light has a CRI of 100. White LEDs offer the industry’s highest CRI, making objects to be illuminated appear more natural and vibrant.
Conformal Phosphor Coating Process
The conformal phosphor coating process uniformly coats the LED with phosphor. This eliminates the blue-ring effect common to other white LEDs and delivers the consistent white color throughout the light beam making the best white LED lighting source available today.
