Title: Lamp Module Voltage Leak?
Post by: don byrne on December 25, 2004, 11:47:42 AM
I have been using lamp modules to control
Christmas candles and they have worked
fine.  My wife wanted to change the bulbs
to ones that look like a candle flame and
flicker.  Now when the module turns off (at
least what would be normal bulbs) the bulbs
dim but do not go out totally.  On an
extension with 2 candles one will go out
and the other will still flicker low.  If I
unscrew the one flickering the other bulb
will come on.  It seems that some how a low
voltage is still getting to the bulb and
that the bulb may not require much to
work.  I have also tried this with an
applicance module and it does the same
thing.  Does anyone have a clue how to
resolve?  Or maybe there is so little
voltage on the bulb that it won't take from
it's life.

Thank you and Merry Christmas
Don

All the X10 modules display this "current leak"--it's actually a feature.

You see, by allowing a small current through a device, you can detect when the non-X10 switch on the device is switched off.  That way, if you don't have a remote control handy, you can still turn a light on by just cycling the device switch off and on.

Other vendors sell modules with a programmable current sense mode which can be disabled.  X10's modules must be disassembled and a wire on the circuit board snipped to make the change.  For details, look at: http://www.idobartana.com/hakb/index.htm (http://www.idobartana.com/hakb/index.htm)

The X10 lamp module was designed for 40-300 watts of incandescent light, which won't power up with the trickle of current.  Those little candle lights are just too darned efficient.
