I have 12v lighting on my patio. The bulbs themselves are LED's. They are on a transformer that comes on at dusk and stays on for 4/8/or till dawn. I have two things I would like to change with this setup.

1. I would like to not only have the transformer come on at dusk, but I would like to put some/all of the lights on a switch. I can do this no problem, but will it hurt the transformer if it is on and I turn all the lights off via a switch?

2. Can I put dimmers on the lights? They are just a bit too bright at times, but not always.

The transformer will not be damaged if you switch the DC side of the transformer, but it will consume a small amount of power. If you can put the switch on the AC side then it will not consume any power.

Low voltage LED dimmer's are available. One example.

I never thought about putting the switch on the a/c side. Not sure why. Brain fart I guess. Of course, I wouldn't have the option to only turn SOME of the lights on/off. It would be all or none. And thanks for that link. That'll be perfect. And cheap too !
