What is Color Light Output
Color Light Output (Color Brightness) is a new standard that gives buyers the data they need to compare projectors. Brightness has long been the specification used for projector comparisons; however the old specification measured only White Light Output, rather than measuring both White Light Output and Color Light Output. The vast majority of the projectors today project color so measuring White Light Output or White Brightness alone is insufficient. Color Light Output or Color Brightness gives the projector buyers the data they need and have been missing.
The Color Light Output (Color Brightness) standard was published in May of 2012. This new specification applies to all displays including projectors for business, education or home. It clearly shows a major difference among projectors. The Color Light Output (Color Brightness) standard, for the first time, gives end users scientific data with which to compare Color. Leading manufacturers have adopted the standard in their product specification to help projector buyers. They now include two measurements – White Brightness (White Light Output) and Color Brightness (Color Light Output).
Projector buyers should look for and demand both numbers – White Brightness (White Light Output) and Color Brightness (Color Light Output). If you can´t find Color Brightness on a product, click here

Independent third party testing sponsored by Epson
1Specifications for Color Brightness and White Brightness are provided by many manufacturers and published by ProjectorCentral.com.
2These manufacturers do not provide a Color Brightness specification for these models. This data was obtained from independent third party laboratory testing of a unit according to
the international standard for measuring Color Brightness, IDMS 15.4.
3This data was obtained from independent third party laboratory testing of the color gamut volume of a unit as measured in 3D in the CIE L*a*b* coordinate space.
