Casio Green Slim projectors - light, bright and mercury free

Up until now, any projector brighter than 2000 lumens has required a high pressure mercury lamp. Casio has announced what it says is the world’s first data projectors capable of delivering up to 3000 lumens in a well lit room that tick the green box by doing away with the use of mercury.
The Green Slim projectors light source uses blue light emitted by a blue laser, green light converted from blue laser light using a fluorescent element, and light emitted by a red LED through a DLP chip. The resulting light means a room no longer needs to be darkened for data projection, with Casio stating that the hybrid LED, laser and fluorescent light source improves the purity of color compared to traditional mercury lamps.
Although pricing and availability are yet to be announced, the Green Slim range will be available in nine variations, with four of the slim 1.7” models set to accommodate WXGA Real Display resolution of 1280x800. Another four of the lightweight 5lbs projectors will have the ability to communicate wirelessly via 802.11b/g Wi-Fi, while several models incorporate PC-free projection through a USB 2.0 host function.
Maximum brightness is possible in eight seconds, with no cool down required, and an auto-correct function does away with vertical distortion should the projector be nudged. Energy efficiency is big on the agenda with Casio promoting the life of the lightsource to be approximately 20,000 hours – almost ten times that of conventional Casio projectors.
While the Green Slim range is aimed at business presentation use, Casio is planning to further develop the line of products incorporating the hybrid LED and laser light source to include smaller projectors for personal use.
