I have 3 halogen 20Watt lights in my stereo furniture that I want to control by X-10. These lights are operated with a 3 way touch pad. There is sometype of transformer that all this hooks into which then plugs into the wall ac. What type of recepticle do I need that will operate these lights. I have a sr227 wall outlet. Will this work on halogen transformer systems?

If there's a transformer involved, then I'm assuming that these are low voltage halogen lights. In that case, then you can't use an X-10 lamp module, but an X-10 appliance module will work fine. The only limitation would be that you can't dim the lights with an appliance module. The other thing I'd be a little concerned about is the touchpad to turn them on. To work with an appliance module (or any X-10 module for that matter) the lights need to be left on all the time, then turned on and off just with the module. If you turn the lights on, then unplug them, then plug them in again do they stay on or turn off? If they stay on, then the appliance module will work just fine. If they turn off, then it may still be possible to control them with X-10, but it won't be easy.

HTH,
