In this report we have two serious solid state, bright, full featured projectors. Panasonic’s RW430 is one, and it offers lots of zoom range, WXGA resolution and a full feature set. Sony’s Laser Projectors, the FHZ55 is the other. It’s a good deal brighter, and is WUXGA/ 1080p and also is fully featured, from networking to interchangeable lenses. Solid state light engines are long life, so lamp replacement is not a factor. They dim in brightness more slowly. They also start up and have a usable image in just a couple of seconds, not more like 30 seconds to a minute for most conventional lamp based projectors. These solid state projectors are truly more expensive per lumen, and that remains the case even when you figure in replacement lamps for the competition, but they do provide a long life, install and forget advantage, with what should be the lowest operational costs. (They are typically more energy efficient as well.) Solid state projectors can typically work 360 degrees and off access – not something needed in the classroom, but often ideal for special projects like a museum art display. That’s doubly true of the projectors also offer edge blending. Click Image to Enlarge
