numbersjunkie Sent them an email about 2 hours ago but it was after hours so I won't hear anything until tomorrow, I'm sure.

No particular recommendations, they are well labeled at the big box stores.

They are expensive, but we are very pleased with the Luton Caseta dimmers. They work fine on their own as a dimmer switch, and if you add a home automation hub, you can control or schedule the lights using a phone app.

Lutron are the gold standard for dimmers, especially LED ones. They do a lot of testing for compatibility. As numbersjunkie recommends, check with the lighting manufacturer. Failing that, go with a Lutron model.

I found that the Lutron dimmers labeled for use with LED lights did not work with my particular lights. After calling Lutron (which had no info for my lights) and perusing both the Sylvania (light manufacturer) and Lutron websites, I discovered the correct dimmer on the Sylvania site.

When I posted about this in lighting, someone recommended this dimmer: dimmer

The CL Dimmer is not the correct type of dimmer for transformer based lighting systems. It is only meant for LED lightbulbs. For a driver based system, you need the Electronic Dimmer (MAELV Dimmer). This allows you to dim the LED driver.

Good luck!

Called vendor again and learned that we need low voltage magnetic dimmers. We can use 1 dimmer with all 3 transformers in the kitchen but it seems easier to buy 3 dimmers. The lighting vendor suggested this one: https://www.amazon.com/Lutron-DVLV-600P-WH-600-Watt-Low-Voltage-Single-Pole/dp/B0006UUI06/ref=sr_1_1?s=hi&ie=UTF8&qid=1472845134&sr=1-1&keywords=Low+Voltage+dimmer+magnetic

homepro01, oh no! I just bought 4 of the CL dimmers for my new recess LED lights. We are adding new recess lights with housing, will the CL dimmers not work?

Guco45,

They will not dim realiably. They will dim in like three steps rather than down to about 10%. Use the electronic dimmer if you can. Lutron can also provide some guidance directly

Katrina,

You can reach out to Lutron to confirm that the Diva magnetic will work with LED fixtures. They are really helpful and knowledgable.

Good luck!

Guco45,

The CL dimmer is made to work with LED lights which do not require a transformer. Unless you got low voltage recessed lights, they should work fine. Are you using LED trim kits? Or just putting LED bulbs in?

Heard back from Lutron: Thank you for your interest in Lutron products. We do
have several low-voltage controls that could control your magnetic and
electronic low-voltage transformers. Some of our most popular
dimmers are the Diva and Maestro lines. Diva MLV model numbers can be
found here;
Diva ELV model numbers can be found here.
Maestro MLV model numbers can be found here;
Maestro ELV model numbers can be found here.

Unfortunately, there is currently no industry standard for
the manufacturing of LEDs and the performance will vary with different dimming
controls. We have not tested the LED fixtures you inquired
about, so we are not able to guarantee a dimming solution for them. I
suggest contacting the manufacturer to see if they can give you a dimmer recommendation
based on their compatibility testing.

Katrina,

What lighting did you select? Do you know if it is a magnetic or electronic transformer?

We have a combination of magnetic and electronic transformers. The kable lights use magnetic transformers while the under cabinet lights have an electronic transformer. I don't know if the other lights have transformers since we are replacing existing fixtures. I need to ask the GC about those.

My first thought is to match the type of transformer to the type of LED switch. For the Magnetic transformers, use the Magnetic LED switch. For the Electronic transformer, you the Electronic dimmer. Have you considered the Lutron Caseta? I just installed some switches and the love and I really like it. The dimmers work with either Magnetic or electronic transformers and the system can be controlled via remotes or your phone.

That looks cool! We are going with Lutron but probably Diva since they will fit the existing boxes. We have 4 switches on one wall (beside the intercom) and the others are solo. The others lights we are replacing with LEDs have no transformers, they are connected to the fuse box.

I have trouble with the buzzing with LED lights, too in standard lights. I got some LEDs at BJ's and they don't buzz. I can check them.

I can tell you that LEDs can be a miserable failure in motion sensors. Electricians think I'm crazy that CFLs flicker (until they see it themselves -- like I"d make that up) even when off. I have two LEDs in my laundry motion sensor controlled pot lights that never go off. They're dimmer, and brighten with motion, but evidently they're not made for motion sensors. Talk about ghost electricity!

This was an informative question. Thanks.

The contractor said order 1 of each type needed to test. We are putting dimmers in for all 12 switches. I'm ordering these:

Lutron DVLV-600P Magnetic Low Voltage Preset Dimmer

Lutron DVELV-300P Electronic Low Voltage Preset Dimmer

Lutron DVCL-153P CL Dimmer
