Where This Product Fits Best

This panel is suited for indoor environments where a 1X4 form factor is required, such as offices, classrooms, corridors, and retail spaces. It is designed to replace 32-watt fluorescent fixtures in grid ceilings.

The IP40 rating allows use in dry locations where protection from solid objects is needed but exposure to water is not expected. The fixture is not intended for wet or high-dust environments.

Adjustable wattage and color temperature make it suitable for spaces where lighting needs may change over time or where matching existing light levels and color is important.

Operating temperature range of -4°F to 122°F supports use in conditioned spaces and some unconditioned areas within those limits.

Performance and Functional Considerations

The selectable wattage allows adjustment of light output to match the needs of the space, with three lumen settings available. Color temperature can be set to 3500K, 4000K, or 5000K to align with occupant preference or existing lighting.

The fixture delivers a wide 110° beam angle for even coverage in standard ceiling grid layouts. The polycarbonate lens minimizes glare and maintains consistent light quality over time.

0-10V dimming is supported for integration with compatible dimming controls. The fixture is rated for 70,000 hours of use, supporting long-term operation with minimal maintenance.

With a CRI of 80+, the panel provides accurate color rendering suitable for most commercial and institutional applications.

Installation and Long-Term Use

This panel is designed for recessed installation in standard drop-in grid ceilings. Surface mounting and chain or cable suspension are also supported if required by site conditions.

The aluminum alloy housing resists corrosion, and the polycarbonate lens is engineered to resist yellowing over time. The fixture is intended for indoor use in dry locations.

The integrated driver includes protections against low voltage, short circuit, and overload events, supporting reliable operation. The fixture weight and low profile allow for straightforward handling during installation.

Routine cleaning of the lens and inspection of electrical connections are recommended to maintain performance over the fixture?s rated lifespan.

How This Fixture Is Commonly Used

After installation, you can set the wattage and color temperature to match the lighting needs of the space. These adjustments are made before energizing the fixture and remain fixed during normal operation.

The wide beam angle provides even illumination across workspaces, corridors, or classrooms. The fixture can be dimmed using a 0-10V control system if installed, allowing you to adjust light levels as needed throughout the day.

Once in place, the fixture requires minimal attention aside from periodic cleaning. The anti-yellowing lens helps maintain consistent light output and appearance over time.

In day-to-day use, the fixture operates quietly and does not require user interaction beyond any dimming adjustments made through the building?s lighting controls.
