LED under cabinet lighting

I bought a kit from Volt and received everything for transforming and dimming, except that they are individual components. Is there a dimmer switch that takes in 120VAC and gives out 12VDC in a single unit that can fit in a typical box in the wall? I would think that this would be easier to wire instead of trying to get these connected when you don't have a way to hide it unless you wire and hang it in the wall (which is not entirely safe).

Thanks!

The picture of the Volt kit shows all the components as separate pieces.

No.... you would need a 120v LED type dimmer and the 120v to 12v adapter.

Ok, can I use power from an existing outlet box, to a 120V dimmer switch and run that to a new outlet to connect the 120v to 12v transformer? I would use the 120v dimmer switch as my dimmer. That means I would not use the 12v dimmer.

I am trying to have standard looking components.

Thanks, again!

Technically that should work as long as the dimmer is compatible with transformer type devices. That would mean the dimmer is ok for LED and CFL dimming. If it says incandescent only then it may not dim correctly.

You may want to install a single receptacle..... not a duplex receptacle, so nothing else can get plugged in and damage the dimmer.

Or you might want to use a dimmer receptacle and plug.

Ok, here is what I plan on doing - please let me know if there is a flaw with this approach.

Run power from existing outlet box to a new outlet box where I will use a 120 V dimmer.

The outlet of the dimmer is then run to another box utilizing the dimmer receptacle/plug from the previous post.

The transformer, as shown in the picture, is then "plugged" in. The transformer's 12V output will be used for the LED lighting.

You may see in the picture a white dimmer (12V) that will not be used for I will be performing the dimming function through the 120V dimmer.

Does this approach seem reasonable?

Thank you,

You may need an additional incandescent lamp to load the dimmer so it works.

He is dimming the transformer not the lights so the transformer should be an adequate load.

I hope this might help the original poster with his question. I am not sure how applicable this would be, but I found an LED switch that would work great with an LED undercabinet light system. Do a search for Diode LED Switchex Dimmer Switch.

This Switchex light switch has an LED driver built into the switch. So, with this device you can transform from standard 120V to 12V for LED lighting without an additional driver (aka transformer, power supply, or whatever other name). If you have electricity at the switch, then you don't need to use any additional electrical outlet, or any transformer type of device plugged into it.
