Lowes Under counter Lites Dimmer

I am installing http://www.lowes.com/ProductDisplay?partNumber=406089-1390-AC1012-WHG-03LF3-U&langId=-1&storeId=10151&productId=4351953&catalogId=10051 which are 110v under counter lites .

The lites have a touch dimmer feature on a tether cord . Four taps- Off On On On to full bright.
Is there a way to bypass the touch feature and go to full bright on power application ? Bob

  • The lites are 110v. I installed all 5 yesterday. The strip is the dimmer control.
  • The control circuit is likely 12-volts using (3) surface mount voltage regulators most likely 5 volt voltage regulators. This may be a modification where you'll be biting off more than you can chew.
  • Yep. 120 VAC will fry those lights. I've installed many of these in kitchens for customers and the device you want to bypass is a 12V power supply.

    The light pucks themselves, if at all like the ones you linked to (i.e. LEDs), do not operate on 110V power. The little box is also a DC power supply, probably a little switching power supply these days, putting out some modest DC voltage. If you bypass the box completely, you will destroy the lights very quickly...and hopefully that's all that will happen.

  • If you look at the specifications on the transformer/controller block, it should give the voltage output. If it happens to be 12V or so, you presumably could just discard the transformer and run the whole shebang off of the 12V system with a normal 12V switch (or a 12V dimmer if too bright, such as one of these). If they aren't 12V units, you could get some other power supply that meets the current and voltage requirements and wire that in.

    While likely not easy it may be possible with some surgery and reverse engineering of the circuit to bypass/eliminate the dimmer in the existing transformer.
  • Thanks for the link. Those lights are just what I have been looking for to install in the kitchen. The kitchen being the one in our house. :)

    It says it has an on-off rocker switch. Maybe you can leave it at what ever setting you want and just activate it by this switch?
