Definition of Color Temperature

The color temperature is a measurement that is used to define the color of a light source. This is also used to indicate the ‘whiteness’ or ‘warmness’ of a light source.

Our LEDs are available in many levels of Kelvin color temperature. The descriptions used in this site for color temperature conform to the following:

Warm White: 2000-3500 Kelvin: typical incandescent light bulb
White: 3500-4500 Kelvin: typical retail space "white" florescent lighting
Cool White: 4500+ Kelvin: used for high color definition

Examples of Color Temperature

The following table offers a broader example of the types of color temperature:

Color Temp	Example of Source
1900K	Candle light or sunlight at sunrise or sunset.
2000-2700K	Often used as accent lighting to blend in with fluorescent 2700K applications.
3000-3200K	Used as a primary light source for retail applications.
3700K	Coated lamps. Used where a "softer" metal halide light source is desired.
4000K	Used in general lighting; factories: parking lots, warehouses.
5000-5500K	Daylight lamps: horticulture, aquariums, high color definition.
5600K	Nominal sunlight (mid day during mid summer).
6000K	Starts to get a blue tint like some automotive headlights.
