“Lab Tests: What the Meters Say

“BRIGHTNESS. The ZU850 is rated at 8000 lumens. Our test unit equipped with the optional BX-CTA06 lens delivered 8530 lumens in Bright and Constant Power modes thus exceeding its rating . . . most uncommon performance for the majority of today’s projectors.

“BRIGHTNESS UNIFORMITY. The ZU850 exhibited excellent uniformity of about 90%, which is why the ANSI lumen rating of 8000 is not much below the center spec of 8200 lumens.”
