  • 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. 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 and a Hardwire Box with a Rocker Switch. 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 separately.

Specifications & Measurements

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.

Cavity

22in - 23in 21.5in PSP-16-SW
24in - 31in 23.0in PSP-20-SW
32in - 36in 31.0in PSP-22-SW

43in - 48in 42-3/8in PSP-26-SW
49in + 48.25in PSP-28-SW

NOTE: These dimensions assume that the power cord sticks out approximately 2.0in from
one end of the fixture and that nothing is connected to the other end of the fixture.

I Love These
July 29, 2014
I had considered all sorts of ideas before deciding on Pegasus Lighting Microfluorescent T4 light fixtures. I am so glad that I chose these. First of all customer service is fantastic. One bulb was damaged in shipping and they quickly replaced it. My kitchen is beautiful. I chose the warm fluorescent T4 tubes and they look great. They were easy to install and it looks like something a professional has installed. I couldn't be more pleased. Initially, I had considered LED Puck lighting only to realize that somewhere down the line I'd have to replace the entire fixture. But these T4 lights are going to be great. I can purchase the replacement tubes and shipping is done quickly and painless. Customer service is outstanding.
Pros:
Customer Service. The warm lights are truly beautiful.

Great Over Cabinet Lights

Installed over the cabinets and they're great. Nice soft light but really brightens up the kitchen. I really like the extra small profile and installation was quick and easy.

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

Ordered a number of these as over-cabinet lighting for our kitchen.
Pros:
Really light up the entire area very evenly. String together easily.

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

It works.
July 29, 2014
This light was just the size I needed for beneath a kitchen cabinet. The light's color temperature is fairly warm, which I wanted. I agree with another reviewer that the switch could be larger. It was easy to install. I can not yet judge how long it will last.
Pros:
Many size options. Warm light color. Easily installed. Reasonable price.
Cons:
The on/off switch could be larger.

Great lights in our kitchen
May 27, 2014
We've been using this model ever since our kitchen renovation in 2004. We have them under all of our wood cabinets to illuminate prep areas. They are wonderful in all respects: clear lighting, able to focus on one area only if I like, economical to purchase and power. Can't remember how many we have bought over the years, wouldn't use anything else! And Pegasus is an efficient, friendly business, with the customer's needs a number one priority.
Pros:
Warm light, not glaring
Cons:
The one drawback is it's a bit tricky finger-finding the switch, but I know where they are by now.

Excellent light source in dark areas or under lit areas
April 13, 2014
Easy to interconnect and the clips screw in and hold fixtures in place cleanly....such as our custom built closet spans 112 inches wide by 96 inches tall. Easily connected two fixtures to wired and switch on off box which controls on off for both lights easily with one button. The lights do not put out any noticeable heat so safe to use in closed closet near clothes, silk ties and cotton shirts. Great light source and easy do it yourself installation and configuration. Initially bought a pair to try and ordered my second pair for the bottom part of closet separated from the top with a shelf.
Pros:
Easy install, great light and spans the distance needed without any hassle
Cons:
NONE



Questions & Answers
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, 2013

Answer:
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 Diane from Portland on May 9, 2014
Can I buy replacement bulbs? Also, can I replace 6000K bulbs with 3000K bulbs in the same fixture?

By Jacob from Pegasus Lighting on May 12, 2014

Answer:
Replacement light bulbs are available on this page - http://www.pegasuslighting.com/t4-fluorescent-light-bulbs.html

Yes, you can use different color temperature light bulbs in the same 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, 2012

Answer:
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, 2012

Answer:
Pat,

I would use the largest fixture possible to fill your space.

By Linda from Rochester, Pennsylvania on July 22, 2013
I have a 60" space I want to light. Can I inline direct connect an 8" and a 48" light?
By Sue at Pegasus Lighting on July 22, 2013

Answer:
Linda:

The Microfluorescent T4 Light Fixtures (PSP-SW) can be connected directly together using one of the direct connectors that come with each fixture. You could connect a 46.25-inch fixture along with a 9.5-inch fixture for a total of 57.75 inches. Please note that at the end of the run where you insert the power cord into the fixture it adds 2 inches; therefore, you will only have about 0.25-inches of unused space.
By Robert from Mount Upton, NY on July 22, 2013

Answer:
You can, but I suggest 3 20"bulbs instead
By John from Canyon, TX on July 22, 2013

Answer:
Yes, I believe you can; however, I used a 13 1/2" (PSP-8) and a 40 3/8" (PSP-26) to light a 60" space. This combination yields the same wattage, but is around an inch less in total length than your combo. Also, the 8" (PSP-6) does not have it's own on/off switch...which I prefer. I linked the T4 Light Fixtures throughout our kitchen, and have been very satisfied.
By Doug from British Columbia Canada on July 22, 2013

Answer:
Yes you can. You can inline any length together. And it comes with all the hardware to do so. I love these lights!
By Troy from Tukwila, WA on July 22, 2013

Answer:
Yes, you can either use the little connecter piece that should come with your order or you can purchase an extension to connect the two. Either way you do it, you want to make sure you center your lights in your space to get the best results.
By Randy from San Francisco, CA on July 22, 2013

Answer:
Yes, you can connect fixtures of any length to each other. You should allow some way to move them, should one of the fixtures fail. We have had several of these fixtures for about 5 years, and have had a few of them (the actual fixture, not the bulb) fail and have to be replaced.
By Jack from Sacramento, Ca. on July 23, 2013

Answer:
The 48" light centered should be plenty of lighting for the 60" space. If you want the space to be very bright use 6000k daylight. Be careful the 6000k can be harsh with other lighting, you may want to try the 3000k bulb first.

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, 2012

Answer:
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 Stephen Johnson from Columbiana, AL on July 25, 2013
I assume that the power cord plugs into only one end of the T4 fixture. Can the T4 fixture be mounted (reverse ends) so that the power cord is on either the right or left without affecting the profile of the fixture or access to the on/off switch?
By Isaac Vasquez from Phoenix, AZ on July 25, 2013

Answer:
Yes, the power cord plugs into one side. You can mount the T4 fixture either way and it will not affect the look of the fixture. However, if you mount the fixture so that the power cord is on the opposite side (reverse), access to the on/off switch WILL be more difficult as the switch will be in the back, and not the front. Also, if you choose to do it this way (reverse), make sure the mounting clips don't get in the way of the on/off switch.
By FRANK from CUPERTINO, CA on July 25, 2013

Answer:
No. To reverse the direction of the plug the switch will be on the opposite side. IF you mount the light onto a wall the cord will be on the left end with the switch facing down also located near the left end. To place the cord on the right end you need to flip the fixture upside down placing the switch facing upwards. The switch will also be on near the right end.
By Tom from Ny,ny on July 25, 2013

Answer:
This may help answer your question: the switch is on the side of the unit that the plug plugs into. The switch would face you with the plug coming in from the right if it was mounted under a cabinet lets say. The switch would face the wall if you need the plug to come in from the left. The plug can only be on one end, the Male end. The other end is female to connect the units in series.
By BRENT ONSTOTT from Texas on July 26, 2013

Answer:
Most fixtures are mounted against the light shield at the front of the cabinet to maintain the low profile of the fixture. If the fixture is then flipped over, the switch would then be up against the cabinet bottom. If the light shield is deep enough, the fixture may be placed with the tube facing down which would allow access to the switch. Another option is to install the fixture with the switch in the on position and use an outlet that is switched by a wall switch for all the undercounter lighting. Although this may require an electrician, it provides a more elegant solution for all lights.
By Andrew from New York, NY on July 26, 2013

Answer:
Not really....but it comes with mounting clips so it does not totally block off the access to the on/off switch.

The switch is mounted on one side of the fixture, so turning the fixture will always limit access to it, but you should still be able to hit it.

Is there a reason you are not wiring these to a wall switch? Leave the switch for these lights on all the time, but just control at the wall.

Its not like these fixtures are meant to be left visible, so keeping access to the switch on the fixture would be moot.
By George from Antioch, IL on July 26, 2013

Answer:
Yes, the fixture mounts the same in either orientation, but the on/off switch will be on the back side when the power cord is on the left. That is how I have them mounted and I have found that only a minor inconvenience.
By John from Canyon, TX on July 26, 2013

Answer:
The power cord does plug into only one side of the T4 fixture. If ends are reversed, the on/off switch will be affected (i.e. will be reversed).
By Troy from Tukwila, WA on July 26, 2013

Answer:
You are correct, the cord only plugs into one end. Therefore, if you reverse the fixture it will affect the profile and the access to the on/off switch.
By Karen from Hartland, WI on July 26, 2013

Answer:
I think it depends on where you are hanging the fixtures as far as access to the on/off switch. I have all my fixtures facing the same direction with the on/off switch on the same sides, but I have hardwired them. I don't think there would be a difference in the profile if turned in opposite directions. The fixtures can only be connected in one way because there is a "male" connection on one end of the fixture and a "female" connection on the other end.
By Pat D. from Clifton,VA on July 29, 2013

Answer:
I believe the power has to enter from one end only; I have had mine in for a long time so I am going from memory. I reversed one set so the switch was toward the inside of the cabinets which matched up closed to my power supply. Works the same as the other 2 where I reversed them and had the switches facing the outside of the cabinets. I just had to mount them about 1 inch from the edge.

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, 2012

Answer:
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 Dean T from Chicago on November 27, 2013
I want to use this to add light to my home office. The plan is to put them on top of a 90inch long set of bookshelves that are about 78 inches tall in a room that is roughly 10 x 12. Additionally, the room can get very warm, so heat from the fixtures is a concern. First, would this product add a fair amount of ambient light to the room? 2nd, if I preferred a product that can be dimmed, what would you recommend - knowing & accepting that LED will be much more expensive. Thank you in advance.
By Jacob from Pegasus Lighting on November 27, 2013

Answer:
Dean,

1. Yes, these will provide an adequate amount of ambient lighting when used over a bookshelf.

2. For a dimmable light that can be used in the same application, there are a plethora of options. I would suggest browsing our strip lights page - http://www.pegasuslighting.com/strip-lights.html There are options to fit any budget, even when dimming.

Please let us know if we can be of any more assistance.

By Bob from Lewes, DE on January 15, 2013
Are they dimmable?
By Jacob from Pegasus Lighting on January 15, 2013

Answer:
Bob,

Thanks for the question.

No. Like most fluorescent light fixtures, these are not dimmable.

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, 2013

Answer:
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.
