From EIKI — The Eiki EK-850LU is the first LCD projector with a laser light source in the Eiki line of professional high-power projectors. The EK-850LU provides quiet operation and high brightness thanks to the innovative cooling system. The cooling system is a sealed housing that protects the optical system from dust. Therefore, the design of the projector does not require an air filter, which ensures the high reliability of the projector and lower fan noise. Moreover, this model reproduces images with perfect color reproduction thanks to the combination of 3LCD and a laser light source.

  • 100,000:1 dynamic contrast ratio
  • Laser phosphorus technology provides 20,000 hours of laser life
  • A combination of 3LCD and laser light source provides perfect color rendering
  • An innovative cooling system makes operation quiet and allows high brightness
  • 8,500 Center lumens

ANSI LUMENS  is the most commonly accepted industry standard brightness measurement. The ANSI lumen rating measures the brightest white that a projector can produce by averaging nine light meter measurements taken across the projected image.

CENTER LUMENS  measures the spot in the center of a 100% white image, which is often brighter than the rest of the projected image. Thus, it does not provide as accurate a reading of overall brightness as the industry-standard ANSI Lumens measurement, which averages the brightness across nine measurement points.
