ANSI LUMENS  is the most commonly accepted industry standard brightness measurement. The ANSI lumen rating measures the brightest white that a projector can produce by averaging nine light meter measurements taken across the projected image.

ISO LUMENS  is a near-ANSI equivalent used by some manufacturers in place of an ANSI measurement. The measuring technique is defined in the ISO 21118 specification.
