A unit of measure used to measure the brightness of a projector. Specifically, measured by projecting a 40-inch diagonal screen into a plain matte white surface, and dividing the screen into 9 parts equal parts of 3 across and 3 down, while measuring the brightness level of each of the 9 parts, and obtaining the average brightness of these 9 parts.

ANSI stands for the American National Standards Institute. ANSI is a non-profit organization that developed the standards for determining light output or brightness, measured in lumens. Lumens are the standard measurement for light output and the higher the lumen count, the brighter the projection.

A standard for measuring light output, used for comparing projectors. Unfortunately, there are enough variables, that the eye will often disagree radically with the ANSI rating. At best, ANSI lumens do fairly well comparing "apples" to "apples". If however one projector uses Halogen lamps and another metal-halide, the halogen projector will seem noticeably dimmer even if the two units rate the same. Other variables, including type of LCD technology (active matrix TFT, Poly-Si, passive), type of overall technology (LCD vs. DLP vs. CRT), contrast ratios, etc. all effect the end result.

American National Standards Institute A standards-setting, non-governmental organization that develops and publishes standards for voluntary use in the United States. Lumens are the standard measure of brightness set by the institute.

Standard brightness measurement in an LCD projector. Measures the level of brightness at the screen of a projected image.

ANSI lumens refers to the degree of brightness illuminated in a projector's display, measured in "candles". A projector with 2000 ANSI lumens is twice as bright as one that has 1000 ANSI lumens.

Refers to the brightness of a projector. The higher this figure, the brighter the image will be. Anything in excess of 800 Ansi lumens should be viewable in daylight.

A measurement of the overall projector brightness, representing the average value of 9 points on the projected screen image on a scale devised by the American National Standards Institute (ANSI). See also Lumens.

A unit to indicate lumen brightness of projectors. ANSI (American National Standards Institute) has established the standard for measurement of lumen brightness. The lumen brightness value measured under this method is shown as ANSI lumens.

ANSI lumens is a scale to measure the overall brightness value for projectors. The measurement represents the average value of 9 points on the projected screen image.

ANSI is an acronym for the American National Standards Institute, an organizational body that creates standards for the computer industry. Lumens is a standardized method of measuring the average brightness of projection devices. The brighter the image, the more heat generated and power consumed.

(Measure of Brightness) This measure of light output of a projected image is one of the faster evolving characteristics in today's projectors. How do you know what's right for you? Consider the room size and ambient light characteristics: Normal-sized meeting rooms (holding 10 or fewer people) in normal working light: 800 Lumens For medium-sized boardrooms (10-20 people) in normal light: 1000-1300 Lumens For big halls and auditoriums in normal light: 1300+ Lumens.

ANSI stands for American National Standards Institute. It is a standard for measuring light output. Different lamps play a role on light output. Halogen lamps appear dimmer than another metal-halide, even if the two units have the same ANSI lumen rating. Type of LCD technology (active matrix TFT, Poly-Si, passive), type of overall technology (LCD vs. DLP vs. CRT), contrast ratios, among other factors can also affect the end result.
