Desire fixtures are evaluated for Color Rendering Index (CRI) and Color Quality Scale
(CQS) performance using measured output spectrum and optimized mix solutions for a
best spectral match to black body sources at 3200K and 5600K. Color fidelity was also
measured. These numbers may fluctuate slightly from fixture to fixture. This is a normal
characteristic of white LEDs, and this kind of variation is highly unlikely to be apparent in
most applications. The performance is the same for all fixture versions.
Vivid at 3200K
Vivid at 5600K
Lustr+ at 3200K
Lustr+ at 5600K
Studio HD at 3200K
Studio HD at 5600K
Studio Tungsten at 3000K
Studio Daylight at 5600K
Desire luminaires provide excellent color rendering, particularly the color-mixing versions.
A Duv rating of 0.000 indicates that the color mix used was exactly on the black body line,
with no green or magenta tint.
Studio Daylight and Studio Tungsten fixtures use only white-type LEDs at a fixed color
temperature in order to maximize output and efficacy.
