[Caution: always be certain that the light bulb is seated properly in both of its sockets. Be sure that both pins of each end are inside their respective socket and that the light bulb is rotated 90 degrees once the pins are in the sockets. Failure to make good electrical contact between the pins and its socket may result in arcing and excessive heating of the socket.]
ELECTRICAL FEATURES
- Quiet Electronic Ballast: lightweight electronic ballast provides instant-on starting with no flickering and cool quiet operation (less heat, less weight, less noise, & lower wattage than a magnetic ballast)
- Energy Efficient: uses only 8, 13, 16, 21, 26 watts of power/fixture respectively (Uses 70% less energy than incandescent lights of equivalent wattage.)
- CA Title 24 Compliant: this thin-inch under cabinet light meets California Title 24 strict energy-efficient requirements
- On/Off Rocker Switch: an on/off rocker switch is pre-installed
- 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.

 By Steve Havanas from Cleveland, OH on August 26, 2012 Are replacement lens (bulb covers) available for this fixture? By Jacob from Pegasus Lighting on August 27, 2012Answer:Steve, I'm sorry - replacement covers are not availableBy Steven Lopez from Durham, NC on September 7, 2012 Does this come in 277V? By Jacob from Pegasus Lighting on September 7, 2012Answer:Steven,
No, it is 120V onlyBy Chuck Higgins from San Diego, CA on October 28, 2012 Will the knockout accept two Romex cables plus a ground? What is the dimension of the knockout? Location? By Jacob from Pegasus Lighting on October 29, 2012Answer:There are multiple 1/2in knockouts located at the rear, top, and ends of the light fixture. I would suspect that being able to fit the cables will be determined by their exact cable size.By Joey from Kingsland, TX on October 29, 2012Answer:The factory knockout is 3/8". I will often drill a 7/8" hole where I want it and insert a black bushing and that will support two 12/2 Romex. It will be difficult to get both wires in the 3/8 hole but possible. By JR from Clemson, SC on October 29, 2012Answer:The fixture is 1" thick. There are three knockouts on the long fixtures, all on the back, each end and the middle. I think the middle one is larger than the ends, probably the full 1", while ends are maybe 3/4". Assuming use with non-metallic Romex® cable, #14 would work. #12 would be mighty crowded.By John from Naples, FL on October 29, 2012Answer:No. It will not. The dimension is about 1/2 inch diameter.By Jim from Winston Salem, NC on October 29, 2012Answer:We have installed with (2) 14/3 wires with no problem.By David Watkins from Bel Air, Maryland on October 29, 2012Answer:Yes, this is feasible. There is a larger knockout in the middle-back to allow placement near the back of a wall cabinet, with a plastic grommet included. There are 2 smaller knockouts on either end, as well, and they do accommodate Romex connectors. Use 14 gauge wire for connections, because of space limitations in the 1 inch housing. By John Blizard, Installer for Vicki from Northern VA on October 29, 2012Answer:I just installed two of these for a customer. The knockout is the standard size that will accept a 3/8" Romex cable connector and you can fit two 12/2 or 14/2 Romex connectors. There are several knockouts available-side, back. I had to use the one in the back. The metal connector supplied with the light is TOO SMALL FOR THE KNOCKOUT IN THE FIXTURE. In the one install I used a standard 3/8" NM cable connector, and the other light fixture came with a plastic grommet type knockout insert which fit and worked fine.
Hope this helps!
JohnBy Jeff B from Tulsa on October 29, 2012Answer:These fixtures have 1/2 KO's that will accommodate 2 Romex cables with ground. I recommend using 16 gauge or less for flexibility. 12 gauge is very tough to work with in these thin fixtures.By Donald from Bullard, TX on October 31, 2012Answer:There are 6 knockouts. Each are 0.5 inches in diameter. Three are located along the back edge (left, right and center) and three on the top surface (left, right and center). Since my light is mounted in a tight space I cannot see if there are any more.
Hope this helps.By Curtis from Syracuse, New York on October 31, 2012Answer:There is a knockout at left and right ends and at the center of the back of the fixture. The knockout approximates the size of a penny. The Romex wire that supplies power to my fixture has a black, white and bare ground wire. This one Romex wire was able to fit into the knockout. Don't know why you will need two of these but the knockout is big enough to tightly fit two Romex wires. |

Bulbs not long lasting, one lamp burned out completely
March 12, 2013
I bought 5 of these lamps 11 months ago. The bulbs are NOT long lasting and frequently burn out AND they are expensive to replace. Then this week, one of the lamps just burned out completely. Smelled bad, like old electrical trains. I am not a happy camper about this. Constantly replacing the bulbs is not what I would expect out of 10,000 hours of use...more like 1,000 hours. I would not buy this product again, it's made in China and I think this explains the poor quality.
Pros:Cheap price, looks nice
Cons:Poor quality, bulbs burn out quickly, one unit burned out in less than a year.

Just what I was looking for
February 17, 2013
I ordered these to replace some direct mount under cabinet light fixtures in my home office. These were the exact size of the ones I was replacing with the added feature of an on/off switch.
Pros:I bought the complete fixture with bulbs cheaper than finding replacement ballasts and bulbs locally. They work just as the ones that I replaced with added feature of the on/off switches.
Cons:I ordered three light fixtures and the internal wiring where you will connect to the ballasts were all different lengths each one. Be prepared if you have to splice in some additional wire to make your connections. Nothing wrong with the quality though.
