What is Colour Light Output

Colour Light Output (Colour 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. The vast majority of the projectors today project colour, so measuring White Light Output or White Brightness alone is insufficient. Colour Light Output or Colour Brightness gives projector buyers the data they need and have been missing.

The Colour Light Output standard was published in May 2012. This new specification applies to all displays, including projectors for business, education or home. It clearly shows a major difference among projectors and for the first time, gives end users scientific data with which to compare colour. 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 Colour Brightness (Colour Light Output).

Projector buyers should look for and demand both numbers – White Brightness (White Light Output) and Colour Brightness (Colour Light Output).
