Order Microfluorescent T4 Grounded Light Fixtures Here
(Hardwire boxes, additional connectors, and spare light bulbs are ordered separately on Accessories tab.)
What's Included: A Microfluorescent T4 Grounded Light Fixture includes a T4 fluorescent lamp, acrylic cover, a small on/off rocker switch located on the body of each fixture (except the 6-watt model), a 6ft power cord & a three-prong grounded plug, one Direct Connector, and mounting clips & screws.
Hardwire Connection: These fixtures cannot be hardwired directly because their profile is simply too small (0.75in by 1.25in). Thus, if you would like to hardwire a T4 grounded fixture, you will need to purchase a special Hardwire Box from the Accessories tab.

- 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
LAMPS
- Lamp 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
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. When the Microfluorescent T4 Grounded Fixtures are linked together one or more of the fixtures may be turned off by using the rocker switch without affecting the other fixtures. If this fixture is hardwired to power, then it may be controlled by a wall switch as long as the rocker switch 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, Direct Connectors with 90 Degree Angle, 3-Way 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.
Please use this Measurement Guide to assist you.
