Pricey yes, worth it, yes.

My setup: [120VAC from house]--> Insteon Dimmer --> LED DC Magnetic Transformer --> 12VDC LED Undercabinet Strip Lights [35 Watts max]

Perfect solution electrically, but a few minor issues:

1) Be aware, that if you don't use a dimmer the manufacture says to reduce the LED load to 50% of rated value. In this case that would be 20-watts. Not a problem for me...and most of you, otherwise why spend $70? (Buy one for $15 if you don't need dimming.)

2) You will need the following hardware: A pair of wire clamp connectors to put in the 1/2" knockout holes so you don't cut the insulation on your wires. This makes it legal and tidy. Also you'll need five smaller wire nuts and two mounting screws.

3) It's a bit over-priced...even though it's high quality and sturdy. I think that $50 would be fair for the 40-watt device...but at this time in history they kinda have you over a barrel.

4) Cover plate screw is tiny and faces in an awkward direction (at least in my installation). I had to wire up the transformer device, close the lid, put the screw back in, and THEN secure the transformer in my enclosure.

Specifically, I used Insteon in-linelinc dimmers with these LED magnetic transformers. I've used several of the Insteon dimmers now for various inductive loads although I try to keep it under 150-Watts per dimmer. Insteon dimmers are rated at 300-Watts for purely resistive loads and with LED lights, 150-watts is a ton of LEDs. As I stated, for this application my load was 35-watts max. Perfect. I will be upgrading my in-linelinc Insteon Dimmers with DIN-rail mounted Insteon Dimmers in the next week...just to tidy up my installation box; I have other DIN rail devices in the same box.

Size Name: 60w Verified Purchase
Be aware, this is a review after only three weeks of use.

I purchased this because:

1) I rebuilt my kitchen and wired it for 120 VAC, under-cabinet-lights powered and controlled from a switch box, which also controlled a three way for overhead kitchen lights and a four way for the dine room;

2) I changed my plans and switched from halide pucks, that required about 700 watts, at 50 watts per light, to LED strip lights that lit the entire counter using only forty watts;

3) Regardless of the lights I used, I wanted them to be dimmable from the main switch box;

4) Less expensive power supplies for "dimmable" LED's required the dimmer on the output, 12VDC side; and,

5) This power supply allowed me to dim on the high voltage (120 VAC) side.

Initially, I used used a much less expensive power supply. It still allowed me to turn LED'S off and on at the main switch box, but I had to dim them from the 12VDC side. This would have required installing another box and fishing lines at the cabinets, near the power supply. So I would have had to control the lights using two boxes at two different location.

This power supply allowed me to stay with my original lay out. That is, everything controlled at the kitchen-dine room switch box (the power supply is mounted under the cabinets, relatively out of site in a corner).

As soon as I installed this, using a standard, 120VAC LED dimmer, and hit the switch, everything came on, and dimmed according to my original intentions.

This was worth the extra money to get the job done.

I have installed two of these magnetic transformers and they work great. They allow you to use a magnetic dimmer in a standard wall plate that is wired in ahead of this transformer. I had a four-gang wall plate with two standard DIVA style incandescent dimmers and I wanted to be able to dim my strip LEDs without using the cheesy knob dimmer that has to be installed after the transformer. I used Lutron DVLV-600P low-voltage magnetic dimmers that cost under $40.00 each at a local electrical supply and that matched my standard incandescent dimmers. The magnetic low-voltage dimmers work perfectly with these transformers. Wire the dimmers in like any other dimmer and then connect this magnetic transformer. You will have to add pigtails to the transformer unless you hard wire it in. The instructions that come with the transformer clearly explain the wiring process. No noticeable noise when in operation and with this combo you can dim the LEDs from full brightness all the way down to darkness. Two thumbs up.

Size Name: 60w Verified Purchase
I am using this transformer as part of my dimmable under cabinet lighting using a low voltage magnetic dimming switch and LED strip lights.

This is the part I was most nervous about; honestly, I was expecting an east-Asia (China) built part with crap instructions. The packaging didn't ease my concern, it came in a box that was precisely the size of the transformer with no packaging material to protect it; the mounting brackets had been bent during shipping. Typical.

Upon opening and readying for installation, I was pleasantly surprised. The documentation was precise, if very short. It was possible to easily look at the documentation, then the transformer, and understand precisely what was needed.

Installation was, therefore, exceedingly simply and fast. I had the transformer installed, powered and running within 30 minutes. This product works great, providing smooth dimming and consistent lighting across the LED series.

I have a load of about 15w on this transformer -- look at the 40w version if you plan only a single roll of LED strip lights.

My qualms (and reason for 4 stars):
1) Packaging. A little foam would be nice, helping prevent damage to the mounting at the minimum.
2) Humming. There is a constant hum during use. It's very low, only noticeable when you're standing next to the transformer. It increases as the power increases. At most, it's audible if you're working on the counter next to the transformer.
