What is the difference between lumen and ansi lumen or how many ansi lumen equals 1000 lumen?

lumen is the measurement of how bright a specific point is, so in reference to the brightness of a projector, this will refer to the brightest part of the projected image.

ANSI lumens is the measurement of the average brightness across the whole image. This gives a more accurate rating of the overall brightness of the projector.
