From what I am reading, it sounds like this dimmer must be placed on the output side of 120v to 12v transformer?

You are correct. This dimmer needs 12V input and will output 12V. It only can work with low voltage lights.

Are you using this for LED tape light? The dimmer is rated for 12 volts. If you hook it up to a power source with a voltage greater than 12 volts the switch may work for awhile, but will eventually get fried.

You can purchase components separately on-line. I don't know about the dimmer but the power supply (transformer) has to match the voltage of the lights, twelve volt or twenty four.

From what I understand a dimmer would need to be added between the transformer and the LED lights. The transformer isn't dimmed it is the power out of the transformer that is dimmed. But you need to use a DC power LED dimmer.

In the description is says: DimmableAll of our power supplies are compatible with dimmers, either 12 volts DC or 110 volts AC varieties.So, which is it??

It is a magnetic low voltage dimmer for use with magnetic transformers. I am using it for in-ceiling halogen lighting. It should not be used for electronic low voltage transformers (I have some of these powering LED strip lighting). Check your transformer. This is also a Maestro Wireless dimmer which can be controlled by an external remote (such as a pico remote). If you don't need this functionality - use a MALV-600 - which is about $30 cheaper.

That's how I have mine set up; in line with a dimmer. It works well and has for the past six months or so. I'm not aware that you need a power supply that is specifically built for "dimming". As far as I know, any power supply will work as long as it outputs the correct voltage.

I would recommend using the 12v dimmer after the power supply. Cutting"Dimming" the power prior to a power supply defeats the purpose of its capability to convert power from 110v AC to 12v DC. This is the one that I used Leegoal LEDwholesalers LED Strip Lights PWM Dimming Controller For LED Lights or Ribbon, 12 Volt 8/10 Amp, 3301

I would just remove the dimmer and plug directly into a switch-controlled outlet. You could use a dimmer switch to control the outlet, which would accomplish your objective.

Mine work fine on my existing 12 Volt AC transformer. Even though this MR16 is dimmable you cannot use a solid-state dimmer on a transformer.

Donna,FYI - I bought and installed this exact system with no difficulty. Your comment/question is too vague to answer. To recap the usual installation: the red dimmer wire must connect to the "+" side of the LED strip, and the black wire must connect to the "-" side. This is mandatory or else the LED's won't turn on. The dimmer is then plugged into the transformer, and naturally the transformer must be plugged into an active 120 volt outlet. Also, double check that you have good connections at the LED strip. If this doesn't help you, please explain in more detail how you have your system set up. I'd be happy to help you.Doobster Donna,FYI - I bought and installed this exact system with no difficulty.

Sure, if you are good with electrical stuff I see no reason why that wouldn't work and sounds like a good idea to me. You'd just have to splice into the existing wires, perhaps pre-tin, butt splice, and using shrink tubing. The dimmer is fed low voltage since it is inline with the transformer output, so not sure if a low voltage style dimmer is req'd, or if you can get by with a standard 120 VAC one (that part I have no idea).

If you want to have dimmable led strips then you should put the dimmer after the power supply. I used a "HitLights 12-24Volt One Channel Touch Dimmer For Solid LED Lighting Strip, 8 Amp" ($12,99) with "HitLights Warm White Double Density 600 LEDs Flexible Light Strip, 3528 Type SMD, 5 Meter or 16.4 Ft, 12 Volt, 48 Watt" ($20.95) and this power supply and it works great. Read the customer review on the dimmer from Beanhall for a neat idea. I followed his/her suggestion and connected the dimmer to a metal fixture so it is a neat touch sensor on/off & dimmer. It wow's the heck out of all on my guests who see it in operation. I don't know if the powersupply works with Lutron dimmer switches but I know trying to control power supplies with dimmer switches at 110V AC can be a lot more of a problem then controlling at 12V DC and they often hum. The approach I took was a lot cheaper.

if each section of lights is powered by its own separate driver(transformer) it will require one dimmer for each driver

John; call lutron tech service. They are very helpful. I install many dimmers and always call them for direction.

I have installed several of these Lutron Dimmer switches around my home. The setting you're trying to install is very much like what I have done in my place. Actually, I even have a room with 6 12V Halogen bulbs (each with its own mini transformer) and it works pretty well. Make sure you get your polarity right at the moment of connecting your wiring to the switch because they are as good as delicate. Other than that, they work just fine.

need more info.If started to flash when dimming to low end then read instructions-That dimmer may have a wheel or lever to ajust low end dimming. I have a several regular 120v skylarks on mine in different locations and they work fine
