Cbus dimmers downlight occasionally not working

Hi all,

I have a set of halogen downlights that occasionally do not turn on.
I can see that the cbus dimmer channel is turning on on the unit but the lights sometimes work and sometimes don't

They were working well for the last few years, and other dimmable downlights are working fine at the same time.

Are the downlights transformers wired directly into the dimmer channels on the cbus dimmer unit or is there something in between the downlight transformer that needs replacing?

thanks

 

There is not usually anything in-between the dimmer output and the light fittings except maybe a circuit breaker if you are in UK.
It could be the light fittings, loose wiring connection or a problem with the CBus dimmer unit.
Likely in that order.
