The Taiwanese OEM manufacturer Chi Lin has created a prototype of the world's first liquid-cooled LED projector. The liquid-cooled RGB LED light source will last for about 6 years of continuous use, meaning that you'll be using it for a long time. It has a 100,000:1 contrast ratio at sizes up to 130 inches.
The lamp produces 600 lumens, making blacks look deep and excellent color contrasts. Thankfully, this is only the prototype. The mass-produced version will be a lot sleeker. 57% sleeker. The liquid cooled LED projector will be available in late 2009. No prices were announced at CEDIA 2008.
