INSTALLATION
- Quiet Electronic Transformer: xenon low voltage ultra-slim lights require a 12-volt electronic transformer to operate properly. We offer a selection of popular electronic transformers on the Accessories tab. To view our complete selection please visit our Electronic Transformers section of our website.
- May be Surface or Recessed Mounted: may be surface mounted or recessed mounted
- Surface Mounted: if this fixture is surface mounted, it will stick down only 13/16in
- Recessed Mounted: if this fixture is recessed mounted, it needs a cutout hole diameter of
2-1/8in and a hole depth of only 9/16in with the outer trim sticking out only 0.25in
- Long Electrical Leads: each Xenon Low Voltage Ultra-Slim Cabinet Light comes with two 24-inch 18 AWG leads with a plastic connector at the end. The plastic connector is simply plugged into a Multi-Tap Connector which, in turn, is hardwired to a transformer. These leads could be lengthened by using additional 18 AWG wire connected with a small terminal block (available for purchase on the Accessories tab.
- Multi-Tap Connectors: multi-tap connectors provide an easy method to wire multiple fixtures to an electronic transformer. Multi-tap connectors come in two sizes; one connector (PNM-143) can accommodate up to 3 fixtures while the other connector (PNM-146) can accommodate up to 6 fixtures (available for purchase on the Accessories tab). To connect the Multi-Tap Connector to a transformer we recommend using a small terminal block. (available for purchase on the Accessories tab).
- Easy to Install: please refer to these Installation Instructions (PDF). Always check local electrical codes and the National Electrical Code (NEC) before installing any lighting products. It is also wise to consult with a licensed electrician in your geographical area about any electrical details that you might have questions about and to make certain that you are satisfying all of the appropriate electrical codes.

Measurement Guide for Xenon Low Voltage Ultra-Slim Lights
When determining how many Xenon Low Voltage Ultra-Slim Lights you will need for under cabinet lighting you first will have to measure the space where the fixtures will be attached. To do this you should NOT measure the face of the cabinets; you should measure the "cavity" under the cabinet where the fixtures will actually be placed. We recommend that you then refer to the following table when determining how many Ultra-Slim Lights you will need. From the range given below select the number of fixtures that seems right for your situation.
| Cavity Measurement |

 By Lisa from DC on December 1, 2012 How many come in each pack? One or two? By Jacob from Pegasus Lighting on December 3, 2012Answer:Lisa,
These are sold individually.By Gab from NY, NY on January 5, 2013 Do they provide warm (yellow) light or white light? How many Ks? By Jacob from Pegasus Lighting on January 7, 2013Answer:Gab,
Kelvin temp is 2800K, which is warm white, almost the exact same as traditional incandescent.By Peter from MN on September 25, 2012 What is a transformer? Is it necessary when you are connecting these lights to a switch?
By Jacob from Pegasus Lighting on September 26, 2012Answer:Yes, a transformer is necessary for these lights regardless of your setup.
A transformer "transforms" your line voltage down to a lower voltage - generally either 12 or 24 volts. These lights require 12 volts.By James from Weehawken, NJ on September 26, 2012Answer:The transformer is necessary for any low-voltage lights whenever you hook them up to line voltage (i.e. the types of wires that you run from your electrical panel to the light, switch whatever -- like Romex or armored cable). Hard wiring a transformer means that you will have use an electrical box to house the transformer and its connections. What I think is a better option is to wire a switch to a standard outlet box, then get a plug-in transformer to plug into the outlet and connect that to these lights (like this one -- http://www.pegasuslighting.com/electronic-transformer-60w-12v-ac-plug-in.html). If you have the space, you can put the outlet and plug-in transformer above your upper cabinets where it won't be seen.By Mary Ellen from Weston, FL on January 21, 2013 I have 4 glass upper cabinets to light...they are 28" wide and 18" high...is one of the xenon ultra slim puck lights enough for each or should I get two per cabinet? Also I'm confused about the transformer...the electrician said they would be hard wired....so can I hide the transformer on top of the cabinets. And which one should I purchase?
By Jacob from Pegasus Lighting on January 22, 2013Answer:Mary,
I would recommend at least 2 lights per 28in.
In terms of the transformer, simply multiple the total # of puck lights by 10W for your total wattage rating. Then select a hardwire transformer equal to or slightly greater than this total.
If you use a total of 8 puck lights that would mean you need a transformer rated for at least 80W.By Brett from NJ on January 26, 2013Answer:I have a 28" wide cabinet and 2 provides good coverage. I used this transformer LVT-151-12V-AC, Electronic Low Voltage 150W 12V AC Transformer, but there are others depending on how many lights you are going to run. I had an electrician hardwire it in a cabinet as you suggest with a switch on a dimmer externally. I then handled installing the lights and wiring through the cabinets myself. You'll also likely need multi-tap connectors and some extra wiring to hook it all up.

No installation instructions
February 5, 2013
We partially installed the lights and they look fine, but are very hot to the touch after a few minutes. Most frustrating was that no installation instructions were included. Because we wanted to recess them, I relied on the Pegasus website instructions that indicated I'd need to drill a hole "2 3/8 inches" in diameter. After buying an expensive 2 3/8" drill bit, I discovered that the instructions were wrong. I need a 2 1/2" drill bit. Very aggravating.
Merchant Response:Temple:
You are right, our website information regarding the diameter hole to cut was wrong. So sorry about the incorrect information and thank you very much for letting us know. We will update our website with the correct diameter hole - 2 1/2 inches.
Pros:Attractive
Cons:Hot

Good for the purpose
August 23, 2012

I recently bought some of these lights for my kitchen remodel. I had an electrician hardwire the transformer, then I did the remainder of the installation myself. I do not think you need as many of the lights as indicated in the directions, consistent with one of the other reviews. I went with one light per cabinet door except two under a larger corner area. Also consistent with a different review, I agree the screw quality was lacking, even with a predrilled hole. I had to be very careful not to strip the screws. I was a little confused when I first received the lights, they were labeled as halogen, however they give you a xenon bulb to swap out. I ended up having to go back to order an additional multitap connector, some terminal blocks, and picked up some extra 18 gauge wire to run everything. They don't end up reaching quite as far as you think they will.
Once installed, they give off great light, are dimmable, and my 3/4 inch light rail pretty effectively masks the installation so I'm happy with the result for the cost.
Pros:Low cost
Great light
Low profile
Cons:Screws
Installation takes some extra parts and wire beyond what is recommended in accessories tab

Cost-effective and Functional
June 27, 2012
Bought these because they are hard wired and dimmable. They were easy to install, came with additional bulbs and look great. They do have a fairly focused beam so you can (a) go with the included diffuser lens or (b) go with the Pegasus number of recommended lights (I went with fewer than they recommended). Only part of my order transmitted and Pegasus called me to make sure I had all the items I would need for the install. Awesome service, and a solid product. They look nice under my kitchen cabinets.
Pros:Easy install
Hard wired
Dimmable
Compact - so they hide well beneath the cabinets
Cons:Light is more focal than expected. Would like a wider beam.

Small but not too convenient for a wall niche
February 29, 2012
I wanted something small enough to fit in our wall niche and this fit the bill. It is small and compact. The only big downside is that the cap doesn't unscrew off counter clockwise as it states. In fact once you push it in, it is very difficult to remove the cap to change the light without significant effort. This really messed up the installation of the niche light. Finally we figured out that if you press the sides at exactly 2 spots, the cap comes off. I have trouble doing it because if you don't do it right, it will not come off. So I give it 3 stars...looks good but will be so difficult to change the light bulbs when mounted in a wall niche.

Xenon slim lights
February 11, 2012
I believe the lights are going to work well. However they were not the easiest to install. The screws provided were very inferior. They tended to screw in sideways. Possible cause... quality of the screw. And the stamp out of the base piece had a rim. Also the screw tended to strip. I ended up using different screws.
I used my existing wiring and did not need the other accessories that I purchased and I have returned them. Working with Pegasus was pleasant experience.
Pros:Slim height, price and Pegasus service
Cons:Poor installation instructions and poor quality of mounting parts.
