Just what I was looking for
Thought our 9 year old Christmas tree would never light again. Found this adaptor and it works beautifully.

Best quality undercounter lights I've found!
These are bright! They include an ON-OFF and dimmer. I've had some installed for YEARS without a problem. Easily attached with 3M VHB tape. Great product!

works great
I originally ordered a 3 light strip kit to install under the shelf over my desk. The lights were so bright I only needed on strip. I ordered a second power supply and switch/dimmer to install under our hanging kitchen cabinets where we needed more light. Both application work very well. I recommend using 3M picture hanging peel and stick strips to install the lights strips, switch and power supply. It's much easier than dealing with all those little screws. =The lights create a nice warm light and when turned all the way down make a great night light.

A must for 5-20 lightbars from lightkiwi.
You have to use this product for 5 to 20 light bars on one plug in cord cirucit. Some kits come with 4 bars,dimmer,power supply with cord.I orded 2 kits stung them together using this power supply.Used under and over the cabnets in the kitchen.And wow what a differance from the old rope lights to the new led light bars.Everything is working great together.

Absolutely LUV them!
Bought one set of three LED's lites. Was very impressed with the cool white light output and ease of installation so I bought a four set kit to go under another set of kitchen cabinets.Bought this larger transformer for insurance. Running the 7 lites off the larger 36 watt transformer, plus now I have 2 smaller 12 watt transformers as spares in case the larger unit should give trouble at some point.

Great product
Installed these in customer's kitchen under cabinet, they were very happy with product, and installation was easier than most LED installations. Very Satisfied, will use again..

No mounting provision was a problem
Power supply worked fine. One area of disappointment was that the power supply transformer has no provision for mounting under the cabinet. I bent up some stiff steel wire to make a basket that I placed the transformer into & screwed it to the underside of the cabinet

Excellent Power Supply for LED lighting.
I have seven 3 watt, 1 foot, LED strips under my cabinets which draw 21 watts at full brightness. This 36 watt power supply barely warms at all when powering my under cabinet lighting. Since it is a switching power supply, it adjusts its output according to the demand of the dimmer setting of the lighting. Very efficient!
