LED bulbs on a dimmer switch?

Does it work? Are there recommendations for/against?

You have to dimmers specifically designed for LEDs or LEDs that are marked for use with dimmers.

LED are low voltage and therefore require a transformer to drop the voltage down from 120v. Transformers don't like being on a dimmer. That's why you need to KNOW if and how a LED light can be dimmed.

The Commercial Electric Halo style LED trims work great with a standard dimmer.

Lutron dimmer are great but you have to get a dimmable magnetic driver. They can be pricey. For a PMW dimmer, they can be installed after the non dimmable driver but most do not look that good.

Here's an install vid.

With a regular dimmer an led will dim a bit then just turn off. Much of time you need a driver in the light capable of dimming the led or an electronic dimmer as stated previously. The system I'm currently installing requires 120v to the light and 0 to 10 volt control to operate the dimming function at the driver for each light. Do your research and find out what you currently have installed in your fixtures.

I'm here to learn too, i do mostly commercial/industrial/new construction and this place is a great way to pick up tips on residential from some good electrical minds. Excuse the spelling, my phone has a mind of it's own.
