Home Depot sells a really nice light switch that works by RF, perfect for the 15-1994. It is great for home-theater, since it does a real nice slow fade-out of the lights.

I picked one up and am really happy with it. Just thought I'd share that.

Please explain. The 15-1994 doesn't send RF. Is this an X-10 controlled switch, so you are implying that an IR-X10 converter such as the IR543 is also used? What was the cost? Do you know if it is identical to other X10-branded switches, or switches by Leviton, PCS, etc? Is it a pushbutton, decora-style pseudo-rocker, or decora-style true rocker?

Very sorry....got my acronyms mixed. The switch is not RF, it is InfraRed.
The switch is not X10, and it is a standalone device with its own IR receiver. It is white, looks like a rocker, but it's really a push-button, with a small rocker to control the range of the dimming.
The cost was about $60 CDN, which I believe should be about $39 US.
The reason I mentioned it was because I had been looking at X10, and didn't want to have to buy all kinds of devices. When I went to Home Depot, they mentioned they were getting this new IR switch very soon, so I waited. Well, they got it, and I love it.
