Model Overview This projector from Digital Galaxy utilizes LED-LCD technology, achieving 805 ANSI lumens and a contrast of 600:1 at a resolution of XGA 1024 x 768. According to Digital Galaxy, the included lamp lasts up to 3000 hours.
To make performance data comparable based on the lumen specifications, we calculated an approximate ANSI lumen value. A look at the light output reveals: The 805 ANSI lumens are sufficient to illuminate an image width of up to 247 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 165 cm.
The projector was released in 2011 and is officially no longer distributed by Digital Galaxy.
