For the most current information on additional dimmer performance testing
for both ETC and non-ETC dimmers, please visit the ETC website:
etcconnect.com/Support/Articles/Dimmer-Settings-for-Use-with-Source-4wrd.aspx
Color rendering and quality
Source 4WRD fixtures are evaluated for Color Rendering Index (CRI) and Color
Quality Scale (CQS) performance using measured output spectrum. 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.
Note:
With AC dimming (line-dimmed) mode, performance
may vary based on the control settings of the dimmer
used. For this reason, ETC recommends using AC dimming
for level-setting or for architectural quality dimming
situations. ETC recommends testing the Source 4
WRD
fixture on all existing dimmers you wish to use.
Use DMX mode when high-performance, live, dynamic
dimming is required.
