Document: You don't have to have a degree in electrical engineering, but if you hurry and make a mistake you can mess it up.
Was able to buy and entire set cheaper than parts for my exsisting lights. What a real deal, and fast service too!
Too many pieces and too much work to put it all together. I wanted something that was not this involved.
This is the first time I have used this brand. It is good lighting and easy to install. All the lights I installed worked great. The only issue I have is I had one bad transformer and to get it replaced is I have to send in the whole set. I have the lights already installed and wiring in place.I would still recommend the product.
These lights are very easy to install w/o having to drill out holes...the wiring is super easy too. The xenon bulbs should last a lot longer than halogen bulbs too. Instructions are very easy to follow.
These lights are awesome and put out great light!! have had them burning for a few months now and everyone that comes over loves the light it puts out on the counter.
These are nice , bright under cabinet lights. I'm happy with the light and color. Price was right, too.But, I've had some problems with bulb life and they do run hot! Not that they heat up the room, but you wouldn't want to touch them and you can feel the heat in the cabinet when they've been running for awhile. I was replacing an existing set with a failed transformer. Next time I'll look for something cooler running.
The hardest part of the 30 minute project was using the cordless drill to screw in the screws upside down.These lights are great and such a great deal. The included halogen bulbs are worth the price alone!! If you want to stay with halogen bulbs instead of the newer (and less attractive) LED lights for your cabinets, I would HIGHLY recommend these lights.
Replaced with same item after many years. The transformer failed after about 10 years of use. I bought the same one and just replace the wiring with transformer.
Originally purchased these light at Lowe's and after 3 years the transformer went out. Lowe's discontinued product and so I purchased it from amazon. It was a much easier installation for me since I did not have to replace the lighting pucks, only the electrical cords. They worked perfectly and are very cost efficient.
