The ransformer suits our needs.

We've purchase W.A.C. products in the past and our experience here is no different: a quality product at a reasonable price, which is easy to install.

Just right for a specific application.

We needed it urgently, found it at YLighting and got it overnight. Instant solution to a loopback problem.

Transformer works fine

I'm not sure how to review a transformer, but it does what it is supposed to do, so what more can you ask for? The guy who installed my lights told me it is a very high quality transformer, and I believe him.

Its a transformer as long as it works, which it does, what is there not to like.

I had one of the same transformer installed before this one and it went bad which is very surprising to me. I am an electritian by trade and these items should realitvely last forever for what a homeowner asks of the device. I did write A.I.G and never heard back. That is my only negative, not with ylighting but with A.I.G.

Great product!

When dimming make sure you use a dimmer for electronics supply

By:David S. (Vermont)

Perfect solution for low voltage lighting

These power supplies work great when properly used. You must meet the minimum load requirement, not exceed the maximum load and use dimmers for electronic power supplies if dimming.

Replaced two that burned out

These have a short life and we run them at less than their rated wattage. The third time around I went to local lighting store and bought a magnetic transformer which has lasted much better.

Only transformer to work

I had around 4" of space in one location and wanted to really do Bruck pendants. There were very few transformers that would fit in that space. This one fit perfectly, and was the only option available. I have yet to see how long it lasts, but so far it worked out well in the space.

Good Value, easy to install

The nice thing about this transformer is that it comes with a 3 compartment electrical box. One compartment holds the transformer. The other two compartments are for making the electrical connections. The connection for the high voltage side and the low voltage side are separated, making for a safe install. All you need is wire clamps and wire nuts. Works great and upgraded the wattage on my WAC monorail system with this transformer.

works well and comes in its own junction box.

Y lighting was very efficient and competitively priced. This small transformer comes with its own junction box which keeps the connections neatly hidden. Makes for nice wiring.

The only one we use!

It is a reliable high powered electronic transformer that comes in a 3 compartment case. One for the unit, the others for the line voltage connection and low voltage connection. Quick, easy, neat and clean. And priced right too.

Worked like a charm!

I received the transformer within two days of ordering with regular shipping. The installation was quick and easy. I had tried to use another lower cost brand, but the under cabinet lighting wouldn't work properly and my wife wasn't happy. The WAC transformer worked like a charm and all is harmonious on the home front once again.

Works well with about a 5 yr life

This transformer functions well - that is, it lights the lights and dims appropriately - but I have been disappointed in the life expectancy. Five years seems short to me - altho I have not tried others for comparison. I purchased this from Ylighting - whose customer service was excellent!

By:Stephen B. , Homeowner (California)

I'm hoping this 250 watt transformer will last longer than the 3 100 watt transformers it is replacing.

The other transformers lasted about 5 years. I suspect this one will do better. Plus it has a slow turn-on to extend bulb life. Hope it works.

Fails after 2 years with 225 watt load.

Transformer with 185 watt load was initially installed in July 2009 and has been replaced twice. However transformer with 148 watt load was initially installed in July 2009 is still in service. The duty cycle of these transformers is equivalent.

YLighting Rocks!

I could not ask for a better overal experience then the one I received in ordering and installing the transformer for our under the cabinet puck lights. The transformer was nicely displayed on the web site, easy to order. Ylighting sent timely order confiirmation, shipping, and tracking notifications. The product arrived on time, in excellent condition and with easy to follow installation instructions. This was my first time doing business with YLighting and I have already recommended them to friends.
