Taking the Color Brightness Challenge to the Streets



“Color brightness, color light output, or simply CLO... has an excellent pedigree, as part of the Information Display Measurements Standard.”

–M. David Stone, PCMAG.COM

Understanding Projector Lumens

Brightness is measured in lumens, but there are two specs. When asked, 79% of projector buyers surveyed think a single lumen number means both white and color brightness3.
It does not.

Epson's Advantages over 1-chip DLP Projectors

Epson Projectors have up to 3x Brighter Colors

Frequently Asked Questions (FAQs)

Q: Does the lumens value refer to both white and color brightness (white light output and color light output)?
A: No. Unless specified in the color brightness specifications, only white brightness is noted. Color brightness may be up to 1/3 the value of white brightness.

Q: How is color brightness determined?
A: Color brightness (color light output) is measured in accordance with the IDMS 15.4 standard.

Q: Can there be differences between white and color brightness (white light output and color light output)?
A: Yes. For instance, a projector that produces 3000 lumens of white brightness may produce only 800 lumens of color brightness. This can produce noticeable differences even when similar projector specifications and prices are compared. The expected results might not be attained. The color brightness may be up to 1/3 of the quoted white brightness value. Ask to see both specifications, white brightness and color brightness.

Q: Are lumens from LEDs different from regular lumens?
A: No, the lumens value is a standard international unit of measure and is not dependent on the light source.

Q: Why is color brightness not published?
A: Some projectors have the same level of color brightness as white brightness. Several manufacturers fail to mention that the color brightness of their projectors may be up to 1/3 of the white brightness.

Q: Where can I get more information about color light output (color brightness)?
A: Go to www.colorlightoutput.com
