Order Microfluorescent Adjustable T4 Grounded Light Fixtures Here
(A power cord, hardwire boxes, additional connectors, and
spare light bulbs are ordered separately on Accessories tab.)
What's Included: A Microfluorescent Adjustable T4 Grounded Light Fixture includes a T4 fluorescent lamp, acrylic cover, one Direct Connector, and stainless steel mounting clips & screws for vertical or horizontal mount. To bring power to these units you will need to purchase either a power cord & 3-prong grounded plug or a special Hardwire Box from the Accessories tab.
Hardwire Connection: These fixtures cannot be hardwired directly because their profile is simply too small (7/8in by 1-5/8in). Thus, if you would like to hardwire a T4 Adjustable Grounded Fixture, you will need to purchase a special Hardwire Box from the Accessories tab.

- Adjustable Light Shield: fixtures feature an adjustable light shield that rotates 360° to direct light where you need it
- Solid Construction: fixture frame is constructed of extruded aluminum unlike some T4 fluorescent units that are made of plastic
- 2 Finishes: anodized silver or white enamel finish
- 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 7/8in wide by 1-5/8in 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 an energy efficient T4 fluorescent lamp, acrylic cover, one direct connector, and stainless steel mounting clips with screws for vertical or horizontal mount. The cord & grounded 3-prong plug must be ordered separately in the Accessories tab.
LAMPS
- T4 Lamp Included: an energy-efficient T4 (4/8in diameter) tri-phosphorous fluorescent light bulb with a
color temperature of 3000K (warm white), 4100K (cool white), or 6400K (daylight white) is included with each Adjustable T4 Grounded Light Fixture
- 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)
- 7 Nominal Lengths: 8 lamp nominal lengths of 9in, 13-1/8in, 17in, 18.75in, 20-1/2in, 34in, 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, 24, 28 watts of power/fixture respectively
- Linkable: can be installed as a single unit or as multiple units connected in line with Direct Connectors of various types and/or Flexible Connectors of 6in, 12in, 24in, or 36in. If the distance between two Microfluorescent Adjustable T4 Grounded Light Fixtures is greater than 36 inches, then use two or more Flexible Connectors. For example, if the distance between two Microfluorescent Adjustable T4 Grounded Light Fixtures is 65 inches, use two 36in Flexible Connectors connected end-to-end.
- Maximum Wattage: up to 10 fixtures may be linked together with a maximum total wattage of 350 watts
- 3-Wire Grounded: 3-wire grounded fixtures like these Microfluorescent Adjustable 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

INSTALLATION
- Easy to Install: easy to install with 2 stainless steel screw-in clips, then fixture snaps into place
- Electrical Connections: can easily be connected to power by using either one of three different 6ft power cords or two different Hardwire Boxes. However, these Microfluorescent Adjustable T4 Grounded Light Fixtures cannot be hardwired directly because their profile is simply too small (7/8in by 1-5/8in). The power cords and hardwire boxes can be ordered in the Accessories tab.
- Three Power Cords Available: the required 6ft power cord with a grounded 3-prong plug comes in white and must be ordered separately in the Accessories tab; the optional 6ft right angle power cord with a 3-prong grounded plug comes in white; the optional left angle 6ft power cord with a 3-prong grounded plug comes in white. The optional power cords may be ordered in the Accessories tab.
- Plastic Hardwire Box with Control Switch: will permit the Microfluorescent Adjustable 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 the Microfluorescent Adjustable T4 Grounded Light Fixture.) The optional Hardwire Boxes may be ordered in the Accessories tab.
- Commercial Grade Metal Hardwire Box: will permit the Microfluorescent Adjustable 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 Adjustable T4 Grounded Light Fixture.)
- Optional Accessories: a variety of connectors (Direct Connectors, Direct Connectors with a 90 Degree Angle, 3-Way Direct Connectors, Flexible Connectors, Power Cords, Hardwire Boxes, Mounting Clips, and spare T4 light bulbs) may be ordered on the Accessories tab

Measurement Guide for Microfluorescent Adjustable T4 Grounded Light Fixtures
When determining how many Microfluorescent Adjustable T4 Grounded Light Fixtures and which size you will need for lighting your situation 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 28 inches we recommend that you use the 20-watt fixture that measures 23.25in long, not the 16-watt fixture that measures 21.5in long.
Please use this Measurement Guide to assist you.
