Tim, Maybe the hardwired module is trying to tell you something ... It wants = two friends in the basement. :)=20 I noticed the hardwired modules are more robust than the plug-in = appliance modules - I've ended up making some extension cords with a moulded box = with the X10 Recepticle on the end - particularly for the outdoor christmas = tree - I was blowing up the appliance modules with about 900W of lights... = I've not compared the circuits to know how different they are.=20 (This year I switched to LED Christmas lights - 1400 of them on a 30 = foot tree - pulls about 90 watts - they look great when they are on - but the sense circuit from the X10 gives them a very slight illumination when = they are off - I decided it was only for about 30 days so I ignored it.)

That makes sense. The funny thing is, this is happening on 2 separate = lights in my basement, but out in my garage, I have the same fixture hooked = into one of the hardwired modules, and that's been going fine for over 18 = months. > You need to have something else discharge the inductive spike - like a = > cube surge suppressor AFTER the module before the shop lamps - or a=20 > small 7W bulb > nightlight in parallel with the shops lamps.... That's an easy fix. I'll give it a try and let you know in 6 months or = so. Thanks Tim ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
