Are the lights themselves dimmable?

My LED recessed lights work fine with Lutron dimmers. They did buzz a little with the standard dimmer, so I replaced with an expensive low voltage, which resolved the buzzing. No issues like you describe though.

Yes, they are supposed to be dimmable.

interesting that your Lutron Low Voltage is supposed to be for incandescent/halogen, not LED. I thought an LED switch was needed.

I noticed from that listing that Lutron has 24 hour tech assistance. I am going to call! Thanks, GauchoGordo

I had trouble with the Lutron dimmer with my LEDs. My electrician troubleshooted for an hour or so, re-read, and re-read the paper (that they never read).

Anyway, he said he was going to a conference and would ask.

Came back to say, (despite it saying differently on the boxes) that the Lutron dimmer (master) can only be used with the companion dimmer (this is on a 3 way switch).

I re-read, and now see you are only dealing with 1 switch total (whereas, mine have 2, so the switches have to talk to each other). So, not really the same.

But, I suspect that something is just a little off still with Lutron LED switches.

ALSO, I had read, in trying to troubleshoot ours, that there has to be a certain amount of electrical draw for them to work well. And, finally, a final consideration, check to see that the switch isn't on some sort of weird programming. On my lutron switches, there is a little piece that can be removed, then you push something and hold it for some amount of time, to reprogram it... Do your directions indicate that is at all a possibility?

Dimmers on 3way circuits must be on the line-side switch. It won't work right if installed on the other switch by itself or in addition to the line-side.

raee,
Is it possible that it's not grounded properly?

Well, I think that I may have a solution actually. I started by calling Lutron (who couldn't help), then on their website noticed that they had lists of lights that various switches work with. And my lights weren't on the list for this switch. So I started searching the Sylvania site and found that they recommend for this light:

Dimming
The SYLVANIA ULTRA Light Disk is dimmable to 20% with standard 120V electronic low voltage dimmers (recommended), incandescent or magnetic low voltage dimmers. In some cases, standard incandescent dimmers require a minimum load of typically >40 watts on the circuit for full range dimming performance (four LED modules). For dimming with digital (smart) multi-location dimmers or
when dimming fewer than four LED modules, electronic low-voltage (ELV) dimmers are required (some ELV dimmers need a neutral connection in the wallbox).

So, I am going to buy a standard dimmer and see how that works.

GauchoGordo, it is certainly possible that the ground is inadequate. This is a 1941 house, and most of the wiring that I have seen (as in replacing 2 prong plugs) is old 2 wire cable. I haven't looked into this outlet box, so I don't know if there is anything to ground to other than the box itself.

Have you come up with a solution to this problem? I have bought and installed 7 of these light's in two different rooms. They said dimmable so I assumed they would work with any dimmer that said LED. Wrong. I also bought Lutron Skylark dimmer. major problems. work wonderful with no dimmer but in one room they need to be on a dimmer. Also want to say that I have only 2 lights on a Lutron dimmer and those work fine. It's just the dimmers that have 7 lights that don't work

Yes cowboy249, replacing the Lutron "Toggler for LED" dimmer with an ordinary Lutron "Toggler" dimmer did the trick. Works perfectly, every time, lights come on immediately and the dimming function works too.

Mind, I only have one switch for all the lights. If you have 2 switches for the 7 lights, you might need a different (3way) switch. I don't know anything about using those.

I have 4 LED recessed lights in my hall way and I am using a 3 way switch on it.

I bought the Lutron Maestro CFL Dimmer kit. Worked great. You can even program it to any desired dimming range. Here's a link.
