LED lighting

I've got dimmers (Lutron) on five LED lights now and they have been doing well. Some lights have some buzzing, but I think it's the actual light, and not the dimmer. In any case, it's never been loud enough to bother me in any of the rooms.

I just used these under the cabinets kitchen. There are tabs on the end to add another strand. Really liking them and the light. Comes with a dimmer switch. Probably going to add them around my center island too.

These are more money but like the accessories.

Thanks for new links to look at. My hall light is a sconce that I really don't like. It is a scone because there is duct work immediately above that entire ceiling. Sooooo some sort of LED strip in a track is still on the table for the hallway.

Concerning a 3-way with a dimmer, does it matter to which switch I run the power? Specifically, can I run the power to the non-dimmer 3-way?

Thank you 00tec, I hooked up the relay to one of my doors tonight. Everything works great and I like the positive click of the relay.

Had to run a wire from NC to 85.

As asmo pointed out in post #2, power supply is important. I figured I didn't need much and only went with a 30v and like he said, you can easily see the difference from one end to the next. Look at the picture in post #15 and you can see the left is darker. For this coat closet it doesn't matter, but for anyone doing a more visible project, definitely run the numbers on your power supply. Thanks everyone. The 3-way with a dimmer will go in sometime this week, hopefully tomorrow.

Okay, for LED lights like this: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 (and the Hampton Bay equivalent sold at Home Depot) they require a 0-10v dimmer switch. If you look at the pictures in the link, on the back of the fixture you can see the regular black/white/ground wires, with an additional grey and purple wire. These are the wires for the dimmer. The guys at Home Depot told me to just cap off those wires and use a regular LED dimmer switch. I don't think that will work, so plan on returning the dimmer I bought this morning.

Now, in addition to needing a 0-10v LED dimmer, I also need one that is 3-way, which makes it considerably more difficult to find. The closest I could find on Amazon was this one: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
which is stupid expensive for a switch. It's not the style I want, but the only correct dimmer in white, which is unfortunately a bigger deal than the style of the dimmer. I applied for the Amazon cash-back card (which I was planning on doing anyway) to get an instant $70 off, so I could get this dumb switch for free.

On the bright side, now I get to get back up into my freshly insulated attic and tramp all over again to run even more wires. The fun never ends.
