BenQ LW21 BlueCore Light Projector
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.
20000 Hours of Optimal Brightness and Reliable Performances
The BlueCore light engine, powered by a laser light source in Eco Mode, has nearly three times the lamp life of a traditional mercury lamp. With up to 20000 hours of light source life, the LW21 offers a much more reliable performance with no sudden decrease in brightness.
Instant On/Off Projection Readiness for Classroom Instruction
It only takes a few seconds for the LW21 to reach full brightness using BlueCore technology. In addition, it doesn’t require additional time to cool down. That leaves teachers with more time to teach without having to wait around between classes.
360° Degree Tilt Projection
Thanks to the laser characteristics of the BlueCore light engine and the heat sink design, users have the flexibility to set up the LW21 tilted 360° degrees in either direction around the vertical! This gives teachers the flexibility to place the projector any way they want and optimize limited space.
