Performance & Light Output

This 1x4 troffer delivers high-efficacy illumination at a maximum 30W setting, optimized for continuous operation in commercial spaces. It is equipped with field-selectable technology, allowing installers to toggle between 3500K, 4000K, and 5000K color temperatures directly on the unit. The frosted polycarbonate lens ensures even, volumetric light distribution that significantly reduces screen glare for improved visual comfort, backed by a robust 100,000-hour LED lifespan.

Electrical & Controls

Powered by an isolated, Class 2 constant current driver, the fixture operates smoothly on 120-277V circuits. This specific model features an integrated Microwave (MVS) occupancy sensor, which detects fine motion through minor physical obstructions like bathroom stalls or office partitions, ensuring lights remain on when the space is actively occupied. It also includes 0-10V dimming leads for integration with secondary building management systems.

Construction & Durability

The fixture is constructed from heavy-duty sheet metal, formed into an architectural center-basket profile and finished in a highly durable, high-reflectance white powder coat. The fully enclosed design minimizes dust accumulation and protects the internal LEDs. It is strictly IC rated, authorizing safe, direct contact with standard ceiling insulation, and carries a UL listing for use in damp environments.

Installation & Mounting

Designed for rapid retrofitting and new construction, the luminaire fits easily into standard 1x4 T-grid suspended ceilings. It features pre-installed integral grid clips that bend firmly over the T-bar to secure the unit against seismic activity and vibration. Electrical splices are made easily via the top access plate, and support wire holes are provided for anchoring to the structural ceiling per commercial safety codes.

Frequently Asked Questions

How does the microwave sensor on this fixture work?

The integrated Microwave (MVS) sensor emits high-frequency waves to detect motion. Unlike PIR sensors, microwave technology can detect movement through minor obstructions like glass or thin partitions, making it ideal for restrooms or divided offices.

What is the maximum wattage of this 1x4 troffer?

This fixture operates at a maximum of 30W. Installers can manually reduce the power draw using the field-adjustable switches before mounting to optimize energy savings.

Can I change the color of the light?

Yes, this model features field-selectable CCT. You can toggle between 3500K, 4000K, and 5000K color temperatures on the driver box prior to installation.

Is this fixture safe to use in insulated ceilings?

Yes, the troffer is fully IC rated. It is certified for safe, direct contact with standard building thermal insulation in the ceiling plenum.

Does this fixture require a special grid size to install?

No, it is designed to drop seamlessly into standard 9/16-inch or 15/16-inch exposed flat T-grid commercial ceilings.
