For those who are challenged more by space than budget, Runco's new LS-100d can be mounted flush to the wall directly above or below the screen, taking only 18 inches of depth and producing a 92-inch image. Its LED light source turns on instantly and will last 50,000 hours while consuming 70 percent less power than a conventional lamp. It ain't cheap at $20,000, but that includes an outboard DHD4 video processor.
