LV-7390
22133
Features
High Brightness - 3000 Lumens, High Contrast - 2000:1
The LV-7390's 3000 lumens will produce bright, clearly visible images in spaces from offices and small classrooms to larger classrooms and boardrooms. This projector's high brightness is able to offset a reasonable amount of ambient light in a venue without sacrificing visibility of the image. The projector's built-in auto iris delivers a 2000:1 contrast ratio, ensuring that what you project shows deep blacks and bright whites.
Another key benefit of the LV-7390's AC lamp system is that it lasts up to 6,000 hours in Quiet Mode.
