Note about
measuring
colour
temperature
(CCT)
VELVET Power series incorporate the innovative VELVET technology
based on Selected BIN LED core unit + custom CPU control
softwtare to obtain the wide range of calibrated colour temperatures
combined with a high color rendering index CCT.
We must remark that traditional color meters still in use today are
designed for a full spectrum source such as incandescent lights and
therefore cannot be used to accurately read the correlated color
temperature (CCT) of the light emitted by VELVET and other LED light
fixtures.
The eventual diversions to green display as CC05M or CC10M in hand-
held color meters are due to these unaccuracy on reading of the light
emitted by LED and must not be considered.
To precisely measure the light emitted by VELVET and other LED light
fixtures a spectrometer specially calibrated for LED sources must be used.
VELVET guarantees pure white light with no green deviation and
correct colorimetry of the light delivered by its VELVET LED luminaries
which have been calibrated in laboratory according to CIE 13.3-1995
international standards for measurement of the CRI and chromatic
coordinates (x, and CIE-1931).
