Light timer/dimmer?

The very last circuit (Varying brightness AC lamp) on the page at

looks to be straightforward and easy to build. No expensive or exotic parts; give it a look.

If you'd rather have a kit, look at the slow dimmer kit at

kit #K8029 (SLOW ON-OFF DIMMER). Oopsss.. that one will only handle 200 watts. You could probably replace the triac in the kit with a higher current type... and you might have to put it on a heatsink for the higher power loads. You can probably find that kit at a number of other web vendors.. just Google for Velleman K8029. Looks like the PC board might fit inside a box... but you need to measure to be sure.

The dimmers above are the slow dimmer portion only, they will not control the times your lights turn & off. For that, I recommend that you look at an appliance timer from your local home improvement or tool center. Something like the timer at

That should get you going in short order.

I believe that some of the professional-grade X10 light-dimmer control circuits have this basic capability, and there are probably some variations that can handle up to 600 watts.

FWIW, the "regular" X10 controllers can dim from 100% to 0% but they don't want to go the other way; a lamp that's off can only be set to a dimmed brightness by first turning it on (=100%) and then dimming it. Once it's on, of course, the dimming setting can be adjusted up and down; just can't go directly from off to, say, 10%.

Note that the controllers I'm running are pretty old and the newer ones (or other models) may not have this limitation.

I used to be an X10 fan, but now it's Zwave, for me. It's very cool technology.

The Home Settings line from Intermatic stuff will do exactly what you want it to (timing, soft on, soft off).

Thanks!

The modules are a bit pricey, but I don't need many. I'm going to try the Zwave stuffs.

You may be able to use a dawn simulator prodcut. Link is below.
