Viewsonic LS740HD 5000 Lumens Full HD Laser Projector

The Viewsonic LS740HD projector is a third generation laser projector, smaller, more efficient, and powerful. Weighing only 3kg the LS740HD pumps out an impressive 5000 ANSI Lumens perfect for bright rooms or large venue projection. With such power you would expect it to chew through 450-500Watts with a traditional lamp projector. But the LS740HD uses a mere 210Watts for lower power bills and greener operation. With a IP6X sealed optical engine the Viewsonic is made for longevity and is backed by a 3 year warranty.
