Line-dimming
When line-dimming the fixture, set the parameters as shown in the
following tables to ensure that the dimmer is out of regulated mode.
(You may need to adjust dimmer settings for optimal fixture control).
In addition to the recommended settings in the following tables, 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. See
