dimmer question
Friend of mine asked me to replace existing switch with dimmer. The switch controls 4 low voltage lights and 2 incandescent fixtures.
Is there dimmer that can handle combination of low voltage and standard bulbs? Thank you Michal

Never seen one. I thought they were pretty exclusive to each other.

If you tied the switch legs from both fixtures to a switch, when it's turned on you'd have 120 volts going to your low voltage fixtures as well.

I think you'll need two switches.

I've never tried it, Michal, but I suppose it could work. You'd be reducing the input to your 120v bulbs and to the transformer that's operating your low voltage lights. I don't see a downside to trying it and then we'll all know whether it works or not. :)

Those Lutron CFL / LED dimmers may work

It depends of the type of low voltage fixtures. Most of those I have are based on switching supplies. They dim kind of of bit, then to about halfway and then off. More so with LED lamps. I wanted dimmable spots in the bedroom so I could lower them down when reading real books before sleeping. (Yup, I still read paper stuff sometimes.)
Anyway, the low voltage bulbs on that line are based on a magnetic ballast. The fixtures were bigger, heavier, and cost more, but dim smoothly from full to a glimmer as does the regular incandescent lamp on that line. Iím using Lutron dimmer rated for magnetic and incandescent. Dimming LED and CFL Iíve found to always be less than satisfactory.
