- Finish: white enamel
- Solid Construction: fixture frame is constructed of extruded aluminum unlike some T4 fluorescent units that are made of plastic
- Full Fixture Lighting: the end of the T4 lamp is only 0.50in from the end of the fixture unlike some T4 units like this that often have a full 1.50 inches between the end of the lamp and the end of the fixture
- Very Low Profile: only 0.75in wide by 1.25in high
- Very Little Heat: gives off very little heat
- Light Weight: very light weight; depending on size the T4 fixture weighs 5 oz, 7 oz, 9 oz, 10 oz, 11 oz, 17 oz, 19 oz, 22 oz, 25 oz
- Protective Cover: includes a clear, ribbed, attractive, easy-to-clean acrylic cover that protects the fluorescent lamp
- Complete Unit: Microfluorescent T4 Grounded Light Fixture includes a T4 fluorescent lamp, acrylic cover, a small on/off rocker switch located on the body of all of the fixtures except the 6-watt model, a 6ft power cord with a three-prong grounded plug, one direct connector, and mounting clips & screws
LIGHT BULB
- Light Bulb Included: a T4 (4/8in diameter) tri-phosphorous fluorescent lamp with a color temperature of 3000K (warm white), 4100K (cool white), or 6400K (daylight white) is included with each T4 Grounded Light Fixture. Four optional colored T4 lamps are also available: red, blue, green, and black light. (6W lamp does not come in black light.)
- Very Good Lamp Life: rated life is 16,000 hours on average (Lamp is easily replaced.)
(Caution: always be certain that the lamp is seated properly in both of its sockets. Be sure that both pins of each end are inside their respective socket and that the lamp 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.)
- Good Color Rendition: high Color Rendering Index (CRI ) of 82+ for all 3 white lamps (warm white, cool white, daylight white)
- 9 Nominal Lengths: 9 lamp nominal lengths of 9in, 13-1/8in, 17in, 18.75in, 20-9/16in, 28.75in, 34in, 40in, and 45.75in regardless of the color temperature or the color of the lamp
- End of Lamp Life: when a fluorescent light bulb burns out it is always a good idea to turn off the corresponding Microfluorescent fixture. Otherwise, the solid state ballast used inside that fixture can sometimes burn out while trying to start a bad light bulb.
ELECTRICAL FEATURES
- Quiet Electronic Ballast: built-in lightweight electronic ballast provides instant-on starting with no flickering and cool quiet operation
- Energy-Efficient: uses only 6, 8, 12, 16, 20, 22, 24, 26, 28 watts of power/fixture respectively
- Linkable: can be installed as a single unit or as multiple units connected in line with Direct Connectors and/or Flexible Connectors of 6in, 12in, 24in, or 36in. If the distance between two Microfluorescent T4 Fixtures is greater than 36 inches, then use two or more Flexible Connectors. For example, if the distance between two Microfluorescent T4 Fixtures is 65 inches, use two 36in Flexible Connectors connected end-to-end.
- Maximum Wattage: in general, the maximum wattage in one “ganged” line of T4 fixtures is 230 watts. However, if the 22W, 24W, 26W, or the 28W fixtures are connected in a single circuit, only 5 of these fixtures may be “ganged” together. Do not exceed power consumption of 230 watts.
- Rocker Switch Pre-Installed: all of the fixtures (except the 6-watt fixture) come equipped with a small on/off rocker switch on the side of the fixture
- Switching: when these microfluorescent fixtures 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.
- 3-Wire Grounded: 3-wire grounded fixtures like these Microfluorescent T4 Grounded Light Fixtures are strongly recommended for projects that require grounding - especially commercial installations; on the other hand, 2-wire non-grounded microfluorescent fixtures can be used for residential installations
- Not Dimmable: these fluorescent fixtures are not dimmable
INSTALLATION
- Easy to Install: easy to install with 2 screw-in clips, then fixture snaps into place
- Electrical Connections: can easily be connected to power by either using a 6ft power cord & 3-prong grounded plug or a choice of two different Hardwire Boxes. However, these Microfluorescent T4 Grounded Fixtures cannot be hardwired directly because their profile (0.75in by 1.25in) is simply too small.
- Acrylic Hardwire Box with Control Switch: will permit the Microfluorescent T4 Grounded Light Fixture(s) to be hardwired and controlled by the rocker switch on the hardwire box. It has 3 knockouts for electrical connections. (Please remember that a flexible connector of the appropriate length must be used to connect the hardwire box and Microfluorescent T4 Grounded Light Fixture.) The optional Hardwire Boxes may be ordered in the Accessories tab.
- Commercial Grade Metal Hardwire Box: will permit the Microfluorescent T4 Grounded Light Fixture(s) to be hardwired into a circuit controlled by a wall switch. It has 4 knockouts for electrical connections. (Please remember that a Flexible Connector of the appropriate length must be used to connect the hardwire box and a Microfluorescent T4 Grounded Light Fixture.)
- Optional Accessories: a variety of connectors (Direct Connectors, Flexible Connectors, a Power Cord, Hardwire Boxes, and spare T4 light bulbs) may be ordered on the Accessories tab

Measurement Guide for Microfluorescent T4 Grounded Light Fixtures
When determining how many Microfluorescent T4 Grounded Light Fixtures and which size you will need for under cabinet lighting location 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 must measure the "cavity" under the cabinet where the fixtures will actually be placed. We recommend that you "fill up" the cavity space with the largest fixture that can fit. For example, for a space that measures 28 inches we recommend that you use the 20W fixture that measures 23.0in long, not the 16W fixture that measures 21.5in.

 By Cathie from San Francisco on July 30, 2012 Has anyone used this light fixture in a cabinet that houses ceramic figurines? If so, is there a glare off the ceramic? By Gail from San Ramon, CA on August 1, 2012Answer:We have used these lights for +/- 4 years now in our store cabinets. We are antique dealers and display a wide range of glass, porcelain, and ceramic figurines. There is no glare of any item on display. These lights enhance the items under display making them easier to sell. We also use these lights to display jewelry. Once again, they let the jewelry shine with no discolorations. I would highly recommend these lights to anyone. We just purchased more for additional cabinets. By Steve from Memphis, TN on July 31, 2012Answer:It shouldn't glare. The light is a soft light and the fixture has a diffuser cover over the bulb. I don't notice any glare off my countertop or anything sitting on it. This is only my opinion as I do not have ceramic figurines on my countertop.By Seth from Virginia on July 31, 2012Answer:While I have not used it for this purpose, it is like any fluorescent light. I would suggest holding a figurine near any fluorescent to see the effect. It is bright and if used to provide cabinet lighting, it will probably provide the desired results. It is also easy to mount in an inconspicuous place.

Great undercabinet choice
August 27, 2012
I was very pleased with the low-profile and clean appearance of the fixture for under cabinet lighting in my kitchen. I mounted 3 of these in a series along the front edge of the bottom of the wall cabinets horizontally oriented toward the backsplash. This mounting is easy with the optional horizontal mounting hardware. The effect is even indirect lighting for the counter without any glare. Plenty of light and much more light than we would have obtained had we gone with LED. Great selection of sizes. Reasonable price
Pros:Selection of sizes for "custom" install
Light quality (warm white)
Amount of light
Low profile

Excellent little light - Extremely COMPACT!
May 6, 2013
Great little, and I do emphasize little, light that provides a lot of light. Selected the warm white bulb and it really does warm things up. Not at all the typical sterile cool white fluorescent light.
Pros:Very compact
Very good light output

Great lights!
May 6, 2013
I shopped around for undercabinet lights and I think this is one of the best offered by Pegasus.
Pros:Easy to install.
Light weight undercabinet lights.
Cons:some of the connectors are hard to push in, but you'll get in if you wiggle a bit, just be patient.

Really nice light
December 12, 2012
This light performs just as I would have expected. Nice bright light (got the cool white) and easy to install. I do wish they were more easily mountable tucked into a corner under the cabinet. The clips used for installing have to be about 1/8 to 3/16 of an inch away from the front lip of a shelf or cabinet bottom to allow for it to spring open and grip the light fixture when installing it. Otherwise works perfectly.
Pros:Easy to install
Nice bright light
Compact fixture
Cons:Cannot be tucked tightly into a corner

Microfluorescent T4 Grounded Light Fixture
October 2, 2012
Great little fixture with bright light.
Pros:I like that these are linkable and have joiner cables with small plugs. Only small holes need to be drilled from one cabinet to another to join them.
Cons:No dislikes.

T4 Microfluorescent Grounded Light Fixture
August 5, 2012
I purchased this fixture to replace an existing fixture. The replacement took about 2 minutes to complete.
The fixture is being used as an under cabinet application to light a countertop area.
The T5 units are very inexpensive to operate and provide adequate lighting to a wide surface area.
Pros:Would like a link receptacle on each end instead of one link end as the one I received.
Cons:The grounded plug feature.

Lighting fixtures work great
July 10, 2012
Used two fixtures to rebuild an old lighting fixture in a display case. Small size allowed for a great installation. Brighter light than old 15" T8 fixture. Easy wiring!
Pros:Small size, easy interconnect and installation
Cons:Nothing so far

Pantry Lighting: Microfluorescent T4
March 25, 2012
We were not able to view the contents of our pantry (8' W X 8' H X 3' D) at night. The problem was remedied by installing fixtures across the top and sides. The three fixtures provide all the light needed.
Pros:Ease of installation.
Cons:No anchors were provided with the screws to attach the clips to the wall. The screws provided are about 3/8" long and did not provide as secure attachment as I liked, so I purchased my own.

Good light but hurts my eyes a little
February 15, 2012
It's a good light but honestly it's a little too bright and hurts my eyes. I squint if I have to look up in that direction, rather than just using it for the light it casts on the counter.

Attractive and useful product
November 9, 2011
I use four of these in my kitchen along with some other accent lighting. I am more than pleased with the ambiance they create. My only complaint, and it is substantial, is that the fixture fails before the fluorescent bulb wears out. The fixture features an electronic ballast that turns on the fluorescent bulb instantly. The electronic ballast fails well before the bulb ever wears out. Despite this I will continue to use this fixture.
Pros:Ability to place it in an unseen crevice
Cons:Electronic ballast has shorter life than the fluorescent bulb

Great under counter light
April 27, 2011
Good product for the value. Easy to install, works perfectly under a kitchen cabinet.
Pros:Like the linkable nature of these lights
Cons:The location of the toggle switch forces one direction when mounting horizontally and with links.
