High Definition Projectors are a very good way to get 70-inch-plus-sized video imaging at home, but the price of initial purchasing and bulb replacement can accumulate to many thousands of dollars. Generally the average cost of a standard HD projector with mid-range resolution is about $1600.00, with bulb replacements running about $130 each. More than anything the "constant" need to replace the bulbs themselves has been the biggest deterrent for this television alternative (each bulb has roughly 2000 hours of life, compared to the average plasma TV life rated at about 60,000 hours). But what if it was possible--with a little work and some home repair skills--to make an LED projector yourself?
Besides the incredible long lifetime of LEDs eliminating the need for lamp replacement (the average LED is rated at 70,000 hours at maximum efficiency), other advantages of LED projectors include instant-on operation and improved color tones. Ordinary LED technology doesn't produce the intensity and output required to provide the same illumination as arc lams. PhlatLight LEDs changed all that (designed and manufactured by US based Luminus Devices).
With a little ingenuity, we can all get our very own projectors. Find the link here!
