Color Light Output
Share |

About this session:

Color Light Output (Color Brightness) is a 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 project or 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).

This session will explain the standard and measurement process for Color Light Ouput using a lux meter to show real energy measurements from projector to screen. Participants will also gain an understanding on how different illumination technologies affect color and brightness when using different projection technologies.
