Title: Appliance module for LEDs ?
Post by: TundraAuto on December 18, 2014, 04:38:38 PM

Is there yet an X10 appliance module that works properly for LEDs?

I have several ADJ Pinspot LED's that I'd like to put on appliance modules. Like many LEDs the electronics in these don't like anything but completely off or completely on. At low voltages, rather than dim, they flash for a few hours until the power supply burns up. Not a good option. Cutting the local control diode apparently doesn't work according to other threads I've read.

Thanks,

The later CFL friendly Appliance Modules do not have Local Control Sensing. No diode or jumpers in the CFL friendly one.
They still have a very small sensing current so the controller IC knows if the ratchet switch is On or Off.
So there is no appliance module. With any voltage on the output when off.

Most have had to add a small incandescent night light or resistor on the output to dump the small voltage on the output.

Try an LM15A "Socket Rocket". ON-OFF only, no dimming. No current sensing. I use them on LEDs and CFLs.

What size resistor?

I use 33k, 3W.

3W is pretty big.  I found 2W locally.  Think that would do it?

EDIT: Never mind.  I just found that I can get 5x more than my local shop in 3W for about the same price and I don't have to deal with traffic.  Only down side...I sent the payment to China.  But, I suspect they were made there either way, so...

33K at 120 volts is about 0.44 watts.
I would say with a 100% safety margin. Anything over 1 watt will be plenty.
