  • Solid Construction: fixture frame is constructed of extruded aluminum unlike some T5 HO fluorescent units that are made of plastic
  • Finish: white enamel finish
  • Full Fixture Lighting: the end of the T5 HO lamp is only 0.50in from the end of the fixture unlike some T5 HO 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 7/8in wide by 1.75in high
  • Very Little Heat: gives off very little heat
  • Acrylic Diffuser: the acrylic diffuser lamp cover fits securely on the housing of the fixture and distributes light output with the highest efficiency and quality of beam control
  • Complete Unit: includes a T5 high output fluorescent lamp, acrylic cover, a 6ft power cord & a three-prong grounded plug, one direct connector, and stainless steel mounting clips with screws.


  • T5 High Output Lamps: offers increased light output, up to 70% more lumens than standard T5 lamps
  • T5 HO Lamps Included: a T5 high output (5/8in diameter) tri-phosphorous fluorescent lamp with a color temperature of 3000K (warm white), 4100K (cool white), or 6400K (daylight) is included with each Microfluorescent T5 High Output Grounded Light Fixture
  • Very Good Lamp Life: rated life is 20,000 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 white lamps (warm white, cool white, daylight)
  • 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.


  • Quiet Electronic Ballast: built-in lightweight electronic ballast provides instant-on starting with no flickering and cool quiet operation
  • Energy Efficient: uses only 24, 39, 54 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 T5 High Output Light Fixtures is greater than 36 inches, then use two or more Flexible Connectors. For example, if the distance between two Microfluorescent T5 High Output Fixtures is 65 inches, use two 36in Flexible Connectors connected end-to-end.
  • Maximum Wattage: linkable up to 10 fixtures with a maximum of 350 watts
  • 3-Wire Grounded: 3-wire grounded fixtures like these Microfluorescent T5 HO 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


  • 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 the included 6ft power cord or a choice of two different Hardwire Boxes. However, these Microfluorescent T5 High Output Fixtures cannot be hardwired directly to the fixture; their profile is simply too small (7/8in by 1.75in).
  • Plastic Hardwire Box with Control Switch: will permit the Microfluorescent T5 High Output 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 T5 High Output Light Fixture.)
  • Commercial Grade Metal Hardwire Box: will permit the Microfluorescent T5 High Output 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 T5 High Output Light Fixture.)
  • Optional Accessories: a variety of connectors (Direct Connectors, 3-Way Direct Connectors, Flexible Connectors, a Power Cord, Hardwire Boxes, Mounting Clips, and spare T5 light bulbs) may be ordered separately

Specifications & Measurements

When determining how many Microfluorescent T5 High Output Light Fixtures and which size you will need you first will have to measure the space where the fixtures will be attached. We recommend that you "fill up" the space with the largest fixture that can fit. For example, for a space that measures 49 inches we recommend that you use the 46-watt microfluorescent fixture that measures 48.25in long, not the one that measures 36-3/8in.

NOTE: These dimensions assume that the power cord sticks out approximately 2in from
one end of the fixture and that nothing is connected to the other end of the fixture.

Nice Size
December 18, 2013
I have an aloe vera plant given to me in the early 1990s that has always lived under a fluorescent lamp. After years I needed to replace the lamp and wanted one slim and trim enough the bulb wouldn't show below the shelf trim. Also, I wanted one that allowed the bulb to be easily replaced. I was having difficulty finding a combination of the right size fixture and the wattage I needed. This unit should work. My plant will let me know I am sure. The size fits, spare bulbs will be easier to store, and the wattage is about the same currently used. I really like the fact that the fixture is hung with metal clips. Now I will be able to unplug the unit and just snap it out and in when it comes to cleaning the fixture or replacing the bulb. The only negative aspect I have found is this unit does not have a switch. Being that I don't need to cut the lamp off and on that much, I can deal with not having one. Still having to use the plug to turn the light on and off might not work for some of you. At the price of this fixture one would think including a switch (on fixture or in cord) wouldn't be a problem.

Good light output
June 13, 2013
I'm using these fluorescents as indirect bathroom lighting behind a mirror. They provide good color rendering and plenty of brightness. Shipment arrived on time and in perfect condition. Small, lightweight, low profile and bright light -- everything I'd hoped they'd be.
low profile (compact) easily installed and connected

Fantastic little unit
April 17, 2013
This light is unbelievably small, yet it functions perfectly. It can be tucked inconspicuously anywhere. I actually have mine in a lizard vivarium providing UVB light for the little guy and I love it because the fixture is nearly invisible. Awesome.
Tiny Easy to mount Interconnectable Power cord is not wrapped up and kinked, so when you hang it, it can be neatly and easily secured in place (think of all the kinks in a lamp or tv cord when you buy it and how they really never fully go away.)
pricey (yikes)

Couldn't be better!
January 4, 2013
I purchased this to hold an Arcadia UVA/UVB bulb in my bearded dragon's enclosure. I wanted a slim fixture that could be tucked and hidden from view under the lip of the terrarium and this one fit the bill! It has worked flawlessly and I couldn't be happier with my purchase!

Couldn't be Happier!
May 15, 2012
Really great product - worked as expected. Purchased to replace an old lighting system we had for 25+ years. Couldn't be happier! Fast shipment and easy to follow instructions and easy installation!
Great lighting, fast installation - worked as expected!

Questions & Answers
By Dan from Pittsburg, Ca. on January 2, 2013
Is there a "tee" accessory that would allow me to install these lights with power coming in between two units instead of at the end?
By Jacob from Pegasus Lighting on January 2, 2013


I'm sorry but we do not have that type of accessory for this product.

By Scott from Chicago, Illinois on April 29, 2013
Are these fixtures dimmable?

By Jacob from Pegasus Lighting on April 30, 2013

No, they are not dimmable

By Dave from Chester, SD on January 12, 2015
What is the cold start capabilities of this light? 0 degrees, -25 degrees? I am thinking of installing eight units about 3-4 feet above a 32 foot long L shaped work bench in a garage that is insulated but not heated all the time. Based on the 350W total limit this restricts me to using eight of the 39W versions. I would like to use eight of the 54W, why is the wattage limited to 350W total? My shop uses 20 amp circuits, not 15 amp. Could a 20 amp circuit handle 432 watts with one on/off switch? Thanks.
By Jacob from Pegasus Lighting on January 12, 2015


The fixtures will start to 0 degrees Fahrenheit. 25 degrees is getting a bit too low for a consistent start.

Do not exceed the 350W max run regardless of your circuit. This max is based on the internal wiring of the fixtures and the max load that wiring can support. The fixtures can melt and it would be a fire hazard if you exceed the rating. You could separate them into two separate runs if need be.
