Frequently Asked Questions
Q: Does “lumens” cover both Color
Brightness and White Brightness?
A:
No. Unless you see a separate specification
for Color Brightness, you are only getting the
White Brightness of the projector. Color
Brightness may be 1/3 of the brightness stated.
White Brightness of the projector. Color
Brightness may be 1/3 of the brightness stated.
Q: How is Color Brightness determined?
A:
A:
Color Brightness (Color Light Output) is
measured in accordance with IDMS 15.4.
measured in accordance with IDMS 15.4.
Q: Can there be a difference between
Color Brightness and White Brightness?
A:
Yes. For example, a projector with 3000 lumens
of White Brightness may only have 800 lumens
of Color Brightness. Image quality can vary
greatly, even among projectors at similar price
points and with traditional specifications –
you may not get what you paid for. Color
Brightness may be 1/3 of the White Brightness
stated. Look for separate Color Brightness and
White Brightness specifications to ensure you
get the best overall image quality for everything
you display.

the light source.
Q: Why can't I find Color Brightness
as a published specification?
A:
Not all projectors have both High Color
Brightness and High White Brightness, and
many manufacturers may not want you to
know their projectors may be 1/3 as bright
when it comes to color.

What is Color Brightness?
Color Brightness is a scientifically set global
standard that measures a projector’s Color Light
Output. It was concluded that there are such
significant differences in color brightness
performance among different projector models
and brands that color should be measured
separately to provide consumers with fair and
accurate information.

What does it mean to you?
The Color Brightness specification allows you to
make a more informed decision when purchasing
a projector. Color Brightness (or Color Light
Output) measures the brightness of the colors in a
projected image, not just the brightness of white.
This is critically important as most projectors are
used for color content, and color is a critical
component of picture quality.

Where did the spec come from?
A committee of display experts, after extensive
scientific evaluation, established a global standard
– the International Display Metrology Standard
(IDMS). The standard, published in June 2012,
IDMS version 1.03, covers the three leading
international display standards organizations
worldwide – the Society for Information Display
(SID), the Visual Electronics Standards
Association (VESA) and the International
Consortium Display Metrology (ICDM).
