Specifications

- Brightness: 16 foot-Lamberts (fL)

- Contrast Ratio: 221:1

These measurements are taken from the projector in a controlled, home

theater environment. All measurements are made to ANSI/NAPM IT7.228-

1997 specifications using the Photo Research PR-650 SpectraColorimeter

and Minolta LS-100 Luminance Meter, Video Essentials test DVD and a 1.3

gain, 72-inch wide screen. The projector is calibrated to a color temperature of

6,500°K and has a minimum of 150 hours of usage.

The foot-Lambert (fL) is the unit of measurement used in commercial movie

theaters to express image brightness at the screen surface. The Society of

Motion Picture and Television Engineers (SMPTE) specifies 16 fL as the target

image brightness for film-based projectors using an open gate (without film in

the projector). More importantly, today SMPTE specifies 12 fL as the target

image brightness in Digital Cinema theaters. The foot-Lambert measurement is

dependent on screen size, screen gain and projector light output.

Home Theater Calibration Specifications

- Light Output: 412 ANSI Lumens

- Contrast Ratio: (tbd)

Industry-Standard Specifications

- Light Output: 800 ANSI Lumens

- Contrast Ratio: 2500:1

These are typical projector brightness and contrast specifications found in most

companies’ sales literature. Runco includes these measurements in its literature

to allow for direct comparison with other manufacturers’ projectors. These

measurements are typically taken at 9,000

°K to 13,000°K to get expected

performance data when the projector is used in professional, commercial and

industrial displays.
