The VPL-SW235 short throw projector has a number of features to present high quality images while keeping low TCO. This includes brightness of 3000 lumen, so images can be clearly seen even in a bright room. Constant brightness function extends the brightness of the projector over a long period of time. While energy-efficient technologies extend lamp replacement time. The projector also needs only 79 cm to display a large 80-inch image on the screen, which fits perfectly in front of a white board leaving plenty of space. With the fuss-free installation and achievement of less glares or shadows during presentation, the short throw projector offers excellent usability.
