LV-7290
22135
Features
High Brightness - 2200 Lumens, High Contrast - 2000:1
The LV-7290's 2200 lumens will produce bright, clearly visible images, and the 2000:1 contrast ratio from the built-in auto iris will ensure deep blacks and bright whites. These features combine to create images with crisp depth and dimension, making them ideal for use in a classroom, office or boardroom.
Another major benefit of the LV-7290's AC lamp system is that it lasts up to 6,000 hours in Quiet Mode.
