In place of the conventional lamp, BenQ has designed its new LX60ST and LW61ST video projectors around a laser light source.
Company officials claim this eliminates the use of mercury, provides stable illumination, and does away with lamp replacement costs.
The laser source is said to be good for up to 20,000 hours, which is around four times that of a typical mercury lamp and equivalent to 18 years use at three hours a day. Even in a commercial or educational setting, that's still a projected lifetime of around six to nine years.
Other advantages of the laser technology are said to be a 90% reduction in light source power consumption and instant on/off with no need to wait for the (non-existent) lamp to warm up or cool down.
Specifications include 2000 ANSI lumen brightness, XGA/WXGA resolution, 0.6/0.49 short-throw projection, two 10W built-in speakers, microphone input, wireless display feature for iPhone/iPad, LAN display, USB display, and 360-degree tilted projection.
