Down lights dimming continuously on its own

[RichardTM]

Hello.

Today at work some down light (220v) were continuously dimming and "undimming" on their own. We tried 3 diff dimmers (1 from my car, 2 from the shop), changing the switch modules, changing the lamps (220v dimable) lamps but nothing stopped the lights from dimming except from switching light off at the DB.
As a temp fix we have removed the dimmer and made it a normal switching switch (light work 100% now), but the client wants them dimable.

Does anyone have any ideas on what i could do to fix this issue or any ideas on what the issue could be caused by?

Thank you
Richard

What type of dimmers, rotary 2-wire modules,3-wire / 4-wire tactile? Leading or trailing edge? What is the circuit layout ie single way, 2-way switching? What types of lamps, LED's, CFL's, incandescents or a mixture? What is the lighting load in watts? Whats the dimmer/s rating? Apologies, lots of questions.

Thank you for your reply.
We were able to find out the issue. We used a diff type of dimmer. (looks like a normal 12v dimmer but its for 220v and yellow)
Thank you again
