Light has an inherent color, and it can greatly affect how an object or space appears.
Light sources have a rating in degrees Kelvin, based on its predominant wavelength color, typically ranging from about 2000K to 9,000K.
Natural daylight is very blue, or cool and is at the top of the scale at 9,000 K. Meanwhile, HID's are very orange and at the bottom of the scale. Fluorescents and incandescents are in between, and you should know the general Kelvin ratings associated with each.
Remember, the lower the color temperature number, the warmer the light will appear.
|Light Source||Color Temperature (K)|
|Warm White LED||2000-3500|
|Natural White LED||3600-5000|
|Cool white fluorescent||4100-4300|
|Cool White LED||5100-20000|
