- Solid Construction: fixture frame is constructed of metal 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 13/16in wide by 1-5/16in high
- Very Little Heat: gives off very little heat
- Light Weight: very light weight; depending on size the T4 fixture weighs 5 oz, 6 oz, 7 oz, 8 oz, 10 oz, 13 oz, 16 oz, 18 oz, 20 oz
- Protective Cover: includes a clear, ribbed, attractive, easy-to-clean acrylic cover that protects the fluorescent lamp
- Complete Unit: Microfluorescent T4 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 two-prong polarized plug, one direct connector, and mounting clips & screws
LIGHT BULB
- Light Bulb Included: T4 (4/8in diameter) tri-phosphorous fluorescent lamp with a color temperature of 3000K (warm white), 4100K (cool white), or 6400K (daylight white). Four 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)
- Lamp Lengths: 9 different lamp MOL lengths of 9in, 13-1/8in, 17in, 18.75in, 20-9/16in, 28.75in, 34in, 40in, and 45.75in regardless of color temperature or color of 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
- Maximum Wattage: in general, the maximum wattage in one “ganged” line of T4 fixtures is 220 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.
- Linkable: can be installed as a single unit or as multiple units connected with inline 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. You may order optional Flexible Connectors in the Accessories tab. A standard inline Direct Connector comes with each fixture.
- 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.
- 2-Wire Non-Grounded: 2-wire non-grounded fixtures like these Microfluorescent T4 Light Fixtures can
be used for residential installations; on the other hand, 3-wire grounded microfluorescent fixtures are strongly recommended for projects that require grounding - especially commercial 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 6-foot power cord & 2-prong polarized plug or a choice of two different Hardwire Boxes. However, these Microfluorescent T4 units cannot be hardwired directly to the fixture; their profile is simply too small.
- Hardwire Boxes Available: two hardwire boxes are available, a Spec Grade Metal Hardwire Box (PSP-BM: 2.0inH x 1-7/8inW x 2-7/8inL) and a Hardwire Box with a Rocker Switch (PSP-B: 1.5inH x 2.5inW x 4.0inL). Both hardwire boxes require that a Flexible Connector of the appropriate length must be used to connect the hardwire box to a T4 fixture. The optional Hardwire Boxes may be ordered in the Accessories tab.

Measurement Guide for Microfluorescent T4 Light Fixtures
When determining how many Microfluorescent T4 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 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 cavity space that measures 28 inches we recommend that you use the 20W Microfluorescent fixture that measures 23.0in long with the power cord, not the 16-watt fixture that measures 21.5in with the power cord.

one end of the fixture and that nothing is connected to the other end of the fixture. |

 By Philip Panzini from NY on February 20, 2013 I don't need a power cord. I only need the fixture. By Jacob from Pegasus Lighting on February 20, 2013Answer:Philip,
Each fixture includes a power cord. If it's not needed, simply discard it. I'm sorry that we cannot offer only the fixture.By Michael Carlson from Manning, SC on November 26, 2012 I have 17 feet of kitchen cabinet that I want indirect lighting on top. What length of lighting and wattage do you recommend? By Jacob from Pegasus Lighting on November 26, 2012Answer:Michael,
We recommend the longest length fixture that you can fit in the space for the most even illumination pattern.By Pat D from Clifton, VA on December 5, 2012 Trying to decide to use two fixtures to cover 60 inch length area or 2 smaller 21 inch units? Smaller bulbs more available if needed? By Jacob from Pegasus Lighting on December 6, 2012Answer:Pat,
I would use the largest fixture possible to fill your space.By Jack Haney from Las Vegas, NV on August 23, 2012 How do I change the light tube? By Jacob from Pegasus Lighting on August 24, 2012Answer:Jack,
Turn off the fixture and let the lamp cool. Then, remove the acrylic cover of the light fixture. Next, rotate the light bulb 90 degrees and then remove. Repeat in reverse to put new light bulb in.By Jon Burleson CPA from Warrenton, VA 20187 on August 26, 2012 Do you sell just the mounting clips? If so, how much are they plus S&H?
By Jacob from Pegasus Lighting on August 27, 2012Answer:Jon,
See the Accessories tab of this product page for mounting clips. To determine shipping cost, add the clips to your cart and use our shipping calculator.By Bob from Lewes, DE on January 15, 2013 Are they dimmable? By Jacob from Pegasus Lighting on January 15, 2013Answer:Bob,
Thanks for the question.
No. Like most fluorescent light fixtures, these are not dimmable.By Debbie from Springfield, MO on May 2, 2013 Would the 24" T4 be of sufficient wattage to illuminate the inside of a sewing cabinet for task lighting? By Jacob from Pegasus Lighting on May 2, 2013Answer:Debbie,
These fixtures give off plenty of light.
For optimal task lighting, I would suggest purchasing the largest fixture that will fit inside the sewing cabinet. |

T4 Fixtures to light pantry
October 24, 2012
These worked great in my mother's pantry. She's vision impaired and needs lots of light, so I installed fixtures ceiling to floor on the wall inside each side her pantry door. I used a Maestro occupancy sensor in the closet to turn the fixtures on when the door opens. These fixtures are quality and we're very satisfied!
Merchant Response:GREAT IDEA to use a occupancy sensor to turn on the lights!!
Pros:Small size, lots of light, easy to install good quality.

Simply awesome
May 29, 2012
I've used these in a number of applications, undercounter, behind cabinet doors, etc. They have proven themselves over the years to be very reliable. They are really small, can be mounted underneath, or on the side. They come in multiple sizes and can be easily chained together. Finally the bulbs last a long time and are energy efficient. Much better than anything electricians usually install.

Great Microfluorescent Fixtures

Great product... great company to work with
February 28, 2012
I bought these microfluorescent fixtures with black lights to be used as above cabinet lighting. I wanted a blue glow over the cabinets and these were perfect. I worked with Robin to select the right products and she was extremely helpful and knowledgeable. The fluorescents were a replacement for some LED rope lights that stopped working and had dead patches. Pegasus offered to replace the LED rope lights but I chose to go with a different technology. Pegasus took back a return of the rope lights and issued a refund and I was very impressed with how they handled things. I would definitely choose Pegasus Lighting for all future lighting projects.
Pros:low profile

Under Cabinet Install
January 5, 2012
This is a perfect choice for under cabinet installations - it installs easily - can be ordered to fit the exact space and gives more than adequate light on the counter tops and work spaces. Another benefit is the "color" of lamps that are available - this allows the customer to have the "temperature" of light that they may want to set a mood or affect.
Pros:Ease of installation and light quality

We Love Them!
June 15, 2013
We can see now! Under those cabinets! The white light is marvelous! The difference is remarkable! The fixtures are simple. The simple installation brackets worked well. We can now choose to use only 20 or 24 watts -- we bought 2 fixtures for use under 2 cabinets -- instead of the 240 watts from the ceiling lights...and see better!
Pros:Small, undetectable profile
Lightweight, yet durable
Cons:1. Reaching under the cabinet for the on/off rocker switch is an inconvenience.
2. The 6' plug wires are too long, unsightly, required creative concealing and are annoying.
3. No convenience plug.
4. Installation required my being a contortionist, but, that had nothing to do with the fixtures themselves, but, the fact that the installation was under the cabinets. It was not easy!

Excellent Value
May 25, 2013
I had to replace an under counter lamp for my desk. This T4 light fixture was a perfect fit. It's low profile matched the original fixture so that it is not visible when sitting at the desk. Light output is perfect. I only wish it had a black connecting cord instead of white, but that is a very minor problem. Overall, if the electronic ballast lasts, it is great fixture.
Pros:Low profile, easy installation.
Cons:None

T4 Fluorescent light fixture
February 9, 2013
Can't write a review for a product I haven't received yet. I ordered this fixture 9 days ago and I still haven't received it.
My rating is for the especially slow shipping. Tomorrow is Sunday and that will make it 10 days since I ordered the product.
Merchant Response:Unfortunately UPS lost this particular shipment. We have shipped a new fixture to this customer.
Cons:Next time I will order my light from a company closer to my home.
