Irvine, Calif. -
has introduced a pair of short-throw video projectors designed for the education that use a mercury-free blue core light engine.
Models LX60ST and LW61ST were designed for a low total cost of ownership using the blue core light engine that uses a laser light source rather than a traditional mercury lamp to achieve up to 90 percent less light source power consumption, BenQ said.
The technology also optimizes the units' brightness, and offers a longer life span, the company said.
According to BenQ, both models offer an average of 20,000 hours of brightness and produce an ultra-high 80,000:1 contrast ratio.
An instant on/off feature saves time on warm up and cool down, while a manual brightness-level adjustment accommodates different classroom environments.
The SmartEco Advanced mode in both units automatically determines the optimal brightness level based on the input source, while a No Source Detected mode automatically lowers brightness to 10 percent when no display has been detected for more than three minutes.
An Eco Blank mode enables blanking out the LX60ST and LW61ST's screens when not in use to redirect students' focus, while lowering light source power consumption to only 10 percent.
The BenQ blue core light engine classroom projectors offer 2,000 ANSI lumen brightness, XGA/WXGA resolution, and 0.6/0.49 short-throw projection.
The units feature two 10-watt built-in speakers and microphone input, Apple iPhone/iPad wireless display support, LAN display, USB display and 360-degree tilted projection.
