The basic data of the Knoll Systems HT221 includes 1300 ANSI lumens, a resolution of XGA 1024 x 768 as well as a contrast of 800:1. The manufacturer lists the lamp life at 1000 hours. Looking at practical performance, up to 314 cm can be illuminated with 1300 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 209 cm. This device is no longer manufactured and has been removed from Knoll Systems's current lineup.
