A projector from Roverlight is the Vision DWS850, whose DLP model delivers 850 ANSI lumens, a resolution of WVGA 854 x 480 and a contrast of 2300:1. The manufacturer rates the durability of the included lamp at 2000 hours. Looking at practical performance, up to 296 cm can be illuminated with 850 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 197 cm. A look at the data sheet confirms a very subtle fan noise for the projector at just 28 decibels. This model dates back to 2006 and is no longer part of Roverlight's current product range.
