OVERVIEW

BenQ BlueCore Light Engine: a Smarter Alternative to Traditional Lamp

The BenQ LW21 is the first in the world to be equipped BlueCore, a light engine that utilizes the unparalleled qualities of a laser light source to achieve optimized energy efficiency, projection performance and readiness. It also incorporates the BlueCore-enhanced SmartEco™ Advanced technology to further reduce light source power consumption by up to 90% for a significantly lowered total cost of projector maintenance and ownership. Free of mercury, the BenQ LW21 is a safer, smarter and environmentally friendly choice for your school.

80000:1 High Contrast Performance for Ultra Sharp Graphics and Text

Blurry images can be distracting for students to read and can cause eye strains and fatigue. The BlueCore light engine can dim the light source power up to 90% and still achieve a contrast ratio as high as 80000:1. This allows students to learn with ultra sharp images and text so they can focus their attention on learning.
