20,000-Hour Maintenance Free
A newly designed laser light source and advanced electrostatic filter deliver 20,000 hours*3 of maintenance-free for the laser light source only.

Inorganic LCD panels and an inorganic phosphor wheel combine with a dust-proof design for 20,000 hours of warranty*4. Additionally, the laser light source is highly reliable, eliminating the worry of the light burning out during important presentations.

Total Liquid Cooling System
A newly developed liquid cooling system maintains optimal temperatures of key optical elements. The inorganic LCD panels, inorganic phosphor wheel and laser light source are kept at optimal temperature no matter how the projector is installed. This efficient cooling system contributes to minimising body size and noise.

High Contrast Ratio
Add brilliance to your presentations. Boasting stunning brightness of up to 20,000 lumens and a high contrast ratio of more than 2,500,000:1, these projectors enable you to project beautiful, well defined images wherever you are, regardless of ambient light.

Auto Geometry Correction with Built-In Camera
The built-in camera detects images that are not projected correctly, allowing the projector to automatically correct a variety of geometry corrections like corner and curved projections.

Multi-Directional Projection
EB-L20000UNL can be rotated 360° in any direction — horizontally, vertically and rotationally — without any loss in image brightness.

Wide Range of Connectivity
EB- L20000UNL is compatible with a wide range of external devices, and additional ports now include DVI-D, HDMI and HDBaseT. Ideal for large venues, HDBaseT can transmit Full HD video, audio and Ethernet at low cost through cat 5e/6 cables up to 100 metres.

*1 Colour brightness (colour light output) and white brightness (white light output) will vary depending on usage conditions. Colour light output measured in accordance with IDMS 15:4; white light output measured in accordance with ISO 21118.

*2 Maximum speed and range is achievable when used with same enhanced mode technology. Actual data rates, features and performance may vary depending on your computer system, the environment and other factors.

*3 20,000H life for laser light source: Approximate time until brightness decreases 50% from first usage. Measured by acceleration test assuming use of 0.04 - 0.20 mg/m3 of particulate matter. Time varies depending on usage conditions and environments. Replacement of parts other than the light source may be required in a shorter period.

*4 Three years or 20,000 hours, whichever comes first.
