Lamp / Appliance Module no good with LED lights?
ken:
LED Christmas lights don't work with the
lamp OR the appliance module. This may be
due to the LED (diodes) creating noise
inside the modules ???? Is this possible,
and if so what is a quick fix.
Capacitor,etc?? Any suggestions?
Brian H:
You mean you can't turn them on or off at all? Both the lamp and appliance modules have a local control sensing circuit. That lets you cycle the local power switch on the device being controled to turn it on with out an X10 command. Down side is a small amount of current is always flowing through the device being conteolled. That can cause things like CFLs to flicker or turn back on. There is a hack to disable it in an appliance module and a lamp module. In your case the non dimming applaince maybe a better choice. Note warantee on the X10 module is killed.

Cut the diode to kill the current. X10 says that adding a standard small wattage incadescent light [7 watt night light] in the output of the module along with the problem load [a power tap may work] may also fix problems. The small light is an easier thing to try first. Though I have done the cuts on a few appliance modules myself.

Ken,
I can see why the LED lights might not work
on the Lamp Module if there is no
transformer, just a bunch of LEDs in series.
However, the LED lights SHOULD work on the
Appliance Module. Brians suggestion of
disabling the sensing circuit is good if the
lights were stayin ON dimmly (the sensing
circuit is providing enough current to keep
the LEDs conducting). But the sense circuit
should not prevent the LEDS from turning ON
when connected to an Appliance module. Have
you tried a second module?
You MIGHT be able to get the LEDs to work
with a Lamp Module by plugging a 7 watt
night light in with the LEDs (module side,
NOT on the end of the LED sring ;-). Don't
use a lamp module on the short "bookcase"
lights LEDs by GE, since they have a
transformer.
FWIW
Noise might be a problem, but I doubt it
since the LEDs

Thanks for the suggestions, I will try the
lamp module with a nightlight AND LED string
this weekend and I'll respond later. As for
the appliance module not working--I don't
get it either because it's just a set of
relay contacts and not an SCR like the lamp
module that has a small current flow when
OFF.
Brian H:
The appliance module also has a small
current flow if the local sensing circuit
isn't disabled by cutting an internal diode.
