The output groups of an 8 channel dimmer are 1 amp each. Therefore your loads need to less than 1 amp per output group or channel. This roughly equates to 4 x 50 watt LV downlights. Using Iron core ballasts.Originally Posted by Cedric
You will have to calculate the load of the fittings you intend to use and select the appropriate dimmer for the given application.
You may be better of with a 4 channel 2 amp dimmer.
