You may need to increase the SCR Off Time from the default setting. Contact
ETC for assistance in changing the SCR Off Time, or any other CEM classic,
CEM+, or CEM3 settings.

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.
