- Switching: when these fluorescent under cabinet task lights are linked together, an individual fixture may be adjusted by the on/off fixture switch without affecting the other fixtures. Additionally, if multiple fixtures are hardwired to power, then they may be controlled by a single wall switch as long as the rocker switch on each fixture is left in the “on” position.
- Not Dimmable: these fluorescent fixtures are not dimmable
INSTALLATION
- Easy to Install: please refer to these Installation Instructions (PDF). [Caution: 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.]
- Easy to Wire: may be “hard-wired” directly to power source using multiple 1/2in knockouts at the rear of the fixture, the "top" of the fixture, or the two ends of the fixture. Please see the Installation Instructions for details.
- Easy to Connect Multiple Fixtures Together: multiple fixtures can be "daisy-chained" together. One standard household ROMEX® 14/2 wire between each fixture completes the parallel circuit. [Caution: Always check local codes and National Electrical Code (NEC) before installing.]

Measurement Guide for Fluorescent T5 Thin-Inch Light Fixtures
When determining how many Fluorescent T5 Thin-Inch Light Fixtures and which size 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 fixture will actually be placed. We recommend that you "fill up" the cavity space with as many fixtures that can fit. For example, for a space that measures 27 inches we recommend that you use the fixture that measures 24.5in long, not the one that measures 21.25in. This will ensure the countertop below will be uniformly lit.

Bulb CRI a bitBy Brian W from Okoboji, Iowa on June 13, 2011 Unit was well built, high quality, and for a hard to find size (9 inch) the price was terrific. My only beef was that the "Color" of the bulb I received is substantially different that the other fixtures, which all have the same CRI. Not sure why, but something to be aware of when ordering.Pros:Cost

fast shippingPros:simple, easy installI would recommend this item to a friend.Very Good QualityBy Chris from Sacramento, Ca on March 27, 2011 Item arrived very quickly from Pegasus and was packaged well. Light is of solid construction and most importantly for under cabinet lights is very thin. However because it is so thin direct wiring is a little fiddly. Overall extremely pleased with the product and would recommend Pros:Thin
Solid constructionCons:A little difficult to wire upI would recommend this item to a friend.Speedy service, dependable, exactly what I neededBy Ted from Oklahoma on March 23, 2011 This item was hard to find online or locally.

Replaces the 20 year old units I had in the kitchen.I would recommend this item to a friend.A really great value.By George from Pennsylvania on January 19, 2011 Used these for under cabinet lighting in the kitchen. They were easy to install, light up the counter tops well and add a great accent to the tile back splash. They don't show up past the bottom of the cabinet since they are so thin.Pros:Size and ease of installationCons:NothingI would recommend this item to a friend.Prefer the 3By Art from Ohio on January 13, 2011 I was looking for the 3" wide model that I bought previously and really liked, but could only find the 5" available now. The fixture has two bulbs, one side of mine did not work after installation.Cons:One side of the fixture does not work at allMerchant Response:Unfortunately, the 3-inch model this reviewer mentions is an older model of this fixture and is no longer available from the manufacturer.
In addition, we have reached out to this customer to determine why one side of his fixture is not working but, unfortunately, we have not received a response back. Clearly, one side of a fixture not working is not acceptable and if the fixture is at fault we will replace it at no cost to this customer.Great value with lots of sizes available.By Dean from Atlanta on January 5, 2011 Attractive and economical.

Customer Comments about our Fluorescent T5 Thin-Inch Light Fixtures
“Just wanted to let you know how pleased I am with my experiences with your website, customer service and products. I hate to be long-winded, but it's important for me to tell you about my search for under cabinet lighting. Because I'm spending lots of money on a remodel which included gutting the kitchen, I wanted to be sure to choose the best product for the lighting under the new cabinets. After searching at the big box stores and getting no more info than what was written on the lighting display, I tried two local lighting specialty stores. Believe it or not, I was told at one of them by the manager that xenon doesn't have a color temperature. (I decided he had to have been born and raised on a planet with different laws of physics.) No one could really help me at all and seemed totally disinterested in trying to sell me anything. Discouraged, I came home and Googled "under cabinet lighting." Your website is a window on the world of lighting! Oh, my goodness, the articles about lighting, the recommendations, the product descriptions!! I was totally elated, then began to think maybe it was just too good to be true, so I revisited your website a few more times over the next few days. Then.......just to be 100% sure.......I called your toll-free number and talked with a customer service representative. I told her that I wanted WHITE light for the under cabinet lighting: standard fluorescent is too blue, daylight and LED is too green and xenon seems too yellow, so I wanted to be sure to get a color temperature that would be white. I also wanted lighting that would produce as little heat as possible. She recommended the (Fluorescent T5) Thin-Inch (Light Fixtures) with a color temp of 4100K. We talked about my previous experiences for a couple of minutes and I thanked her for being so helpful and we ended the call. After all that, can you believe I was still a little nervous about ordering? A couple of days later, I decided to suck it up and take the plunge. So I measured all the spaces under the cabinets, made my list using your recommendations about installing under each cabinet and filling the under cabinet width and ordered online. The shipment arrived a day early which was a very pleasant surprise. The kitchen is now mostly finished. But the best part of it all is what the under cabinet lighting does for the backsplash! It is AMAZING!! That awesome WHITE light is perfect.......no other word describes it. And after arguing with the electrician about the placement of the fixture at the front of the under cabinet space, not the back, he agreed that the front works best as your website recommends. My experience with Pegasus Associates has been one of the best and easiest of this remodel. Thank you so much! I'm looking forward to having it all done and sending you photos.” – Lea W.
"Your site is very intelligent, informative, and easy to navigate. The products look great (Fluorescent T5 Thin-Inch Fixtures) and I eagerly await mine." – Rachel O.
"You have the best selection, service and prices for the T5 Thin-Inch fixtures."
"I purchased some under-cabinet fixtures (Fluorescent T5 Thin-Inch Fixtures) from Pegasus about a month or so ago but only recently installed them. They fit perfectly and my wife is very pleased with her remodeled kitchen. And I was happy with the price. I’ll remember you folks the next time I’m looking for specialized light fixtures."
