I am doing and energy efficient upgrade by changing a few BR30 (75w??)=20
incadecent with 15 watt dimmable LED lamps. One has a regular dimmer=20
switch that works fine, but the one on an X-10 dimmer switch is dim when=20
"OFF". I understand the Triac (or whatever transistorized switch) has=20
leakage current that is suffient to cause the LED's to glow. I would not=20
think this to be an issue with the X-10 oulet we have that sounds like=20
there is a latching relay inside.

One of the fixes I have seen is to parallel a small incadecent lamp with=20
the LED, but that's not very efficent energy wise.

A call to Leviton, one of the major manufacturers of X-10 resulted in=20
the following comments:
1: X-10 is old technology, and recommended a wireless solution. There is=20
enough wireless polution, and don't want to contribute to that, plus the=20
expense and labor, and that's not part of this discussion.
2: They do not recommend ANY LED's on X-10 systems due to noise. I=20
understand what was said, but my power company reliably reads my=20
electric meter and retrieves the data via power line data transfer.

The real question is: Has anyone used X-10 to control dimmable LED's ,=20
if so, how? Via the Z-10, I only need on/off. Dim is only manually=20
locally. We use the X-10 to turn on/off lights around the house for=20
security purposes.
