Flickering lights on circuit with low voltage and line voltage bulbs
Hoping someone can give me some ideas on a flickering light situation. Here is the background:

On a single circuit I have 6 low voltage lights and 6 line voltage high hats. They are all controlled by 4 switches, 1 of which is a dimmer. When first installed 5 years ago, it worked fine with incandescent bulbs in the high hats. A few weeks ago I switched the incandescent to CFLs. Two weeks later the low voltage lights are flickering (even when not using the dimmer). The CFLs are working fine. The flickering does not happen right when the lights are turned on. It takes anywhere from 2 to 20 minutes for the flickering to start.

I switched the CLFs back to the incandescent and it still happens. Any ideas what it could be?

Thanks a lot!!

Is this a consistent flicker or just random? Is there just one transformer for the six LV lights?

Do all of the lights flicker together (in unison)?
Do the lights ever get brighter than they should be?

Probably a loose connection somewhere, which could be either on the low voltage side (load; transformer secondary) or the line voltage side (input; primary).

Yes, the all flicker together. Only the low voltage though. the line voltage bulbs are fine. I dont think they are any brighter ever. Could it be a loose connection if it does not start until around 20 min after turning it on?

Thanks a lot!

There is a single transformer for the six lights. It is not a random blink. On for a second, off for a second.

thanks in advance,
