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.

CENTER LUMENS  measures the spot in the center of a 100% white image, which is often brighter than the rest of the projected image. Thus, it does not provide as accurate a reading of overall brightness as the industry-standard ANSI Lumens measurement, which averages the brightness across nine measurement points.
