"The VPL-PWZ11 laser projector is a versatile, affordable choice for installation in a wide range of education, business and entertainment environments.
The powerful Z-Phosphor laser light source is teamed with Sony's advanced BrightEra 3LCD projection engine to deliver extremely bright, detail-packed WXGA resolution images with generous 5000 lumens brightness and rich, stable colours. This laser light source allows up to 20,000 hours* of virtually zero maintenance operation without the worry of sudden lamp failures. An automated filter system cuts the hassle of regular dust cleaning. Near-zero maintenance needs are complemented by a range of energy-saving features, significantly driving down total lifetime ownership costs. Constant Bright maintains consistent light output levels throughout the laser's 20,000 hours (at light output mode ""Middle"") recommended lifespan."
