Designed for the Whiteboard sector, the dv 488active model from Liesegang features 2800 ANSI lumens, a native XGA 1024 x 768 resolution and a contrast ratio of 500:1. According to Liesegang, the lamp has a durability of 3000 hours. A look at the light output reveals: The 2800 ANSI lumens are sufficient to illuminate an image width of up to 461 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 307 cm. Additionally, a built-in ambient light sensor measures the room lighting and automatically adjusts the projection settings. Specifically for the educational or business sector, an interactive whiteboard function is also integrated. The projector was released in 2007 and is officially no longer distributed by Liesegang.
