nec's widescreen UM330W is a 3300-lumen ultra short throw projector that packs a multitude of features while delivering an extremely short throw distance for education and corporate applications. A complete interactive projector solution can be created using the optional NP02Wi eBeam interactive system. With its ability to be mounted to the wall directly above the screen on which it projects, this model helps eliminate the shadows and glare typically found with standard projection systems. Many non-authentic, non-OEM lamps can stop functioning within 6 to 12 months whether the projector has been used or not. Generic lamps may produce a darker or brighter image than an OEM lamp. Non-authentic lamps die more quickly because of inferior build quality, when the gas sealed within the lamp begin.
