Projector lamps are mostly between 300-400$ to replace and they last between 3000-4000 hours mostly. all depending on manufacturer. (lookup the link

The reason for this is that their fundamental operation relies on crystals moving in a viscous liquid and, like wading in treacle, it’s a very slow process. Early generation LCD panels simply could not switch pixels on and off fast enough to cope with a moving video image, and consequently remained in clock displays and PC monitors that were predominantly used for near-static images. Thankfully, as the technology has developed, the pixel-switching time has dropped dramatically and, in the very best models, causes very little motion blur on moving images. This has opened the floodgates for LCD TVs right up to over 50 inches. However, unlike plasmas, price is no indication of quality.

Hot or Not?

LCD contrast ratio is generally poorer than any other TV technology as the backlight can leak through the “switched off” pixels. A potent backlight can lift the brightness figures, but colour is dependent on single block filtering, so the total range of colours and the colour saturation are also mediocre. The deep liquid crystal substrate means the picture integrity fades away as you move off axis, although the latest models claim a viewing angle up to 170 degrees. That said, manufacturer’s specification sheets can read like Tolkien-scale fiction at times, so getting a demonstration of an LCD TV before you buy is essential. So why is LCD currently the must-have technology? Not only are LCD TVs a super slim flat panel, they are much lighter in weight...
