The Casio Signature Model projectors have increased I/O connectivity, are 3D ready & have auto brightness adjustment to save power & reduce eye fatigue. By combining a laser, a fluorescent element & an LED Casio has created an original mercury-free hybrid light source capable of generating high brightness. Casio has achieved high brightness output of green light, which until now, has been considered difficult with conventional semiconductor light sources, by efficiently converting blue laser light into green light using a fluorescent element. Mercury free light source provides 10x longer light source life than Casio mercury lamp while being more economical based on lamp replacement. The Casio Hybrid Light Source projector features quick startup & shutdown. The projector reaches its maximum brightness in a minimum of 8 seconds & requires no cooling down period. The Casio Hybrid Light Source projectors delivers a 50 percent increase in color spectrum for high impact presentations due to improvements in LED & laser technology. Superior color reproduction enhances color purity allowing visual effects to appear brighter & offering powerful images that conventional projectors cannot match. Compared with conventional high-brightness projectors employing mercury lamps, Casio Hybrid Light Source technology cuts costs as well as the time & effort involved in lamp exchange while maintaining clear, high-quality images over an extended period. Add the excitement of dynamic 3D projection to your business & education applications. Casio projectors can display 3D content from a 3D capable computer. The 1.5x manual zoom lens gives you the flexibility to easily position the projector. Auto brightness adjustment saves power & reduce eye fatigue.
