4 Watt LED Emergency Light | 90 Minute Battery Backup

Product Overview

This 4 watt LED emergency light delivers 300 lumens of backup illumination for up to 90 minutes during power loss. The fixture includes two adjustable LED heads that can be aimed independently to direct light where it is needed most in egress paths, stairwells, or other areas requiring emergency visibility.

The unit operates across 100V-277V input, making it compatible with most commercial and industrial electrical systems. The injection-molded thermoplastic ABS housing provides a durable, lightweight enclosure in a white finish. Wall mounting is the intended installation method.

Where This Product Fits Best

This emergency light is designed for interior commercial and industrial spaces that require code-compliant backup lighting during power outages. Common locations include corridors, stairwells, mechanical rooms, storage areas, and exit pathways where maintained illumination is required for safe egress.

The 120-degree beam angle from each adjustable head allows coverage of wider areas or focused illumination of specific points depending on how the heads are positioned. The universal voltage range supports installation in buildings with varying electrical infrastructure without requiring transformer or driver changes.

Performance and Functional Considerations

At 4 watts, the fixture produces 300 lumens with an efficacy of 75 lumens per watt. The 90-minute battery backup duration meets standard emergency lighting runtime requirements. Rated lifespan is 50,000 hours for the LED components under normal operating conditions.

Electrical characteristics include a power factor of 0.97 and total harmonic distortion under 20 percent. The fixture operates on 50-60Hz frequency. This is a non-dimming fixture intended solely for emergency backup operation.

Installation and Long-Term Use

The fixture mounts directly to the wall using standard hardware. Overall dimensions are 11 inches by 4.5 inches by 2.5 inches, with a unit weight of 19.6 pounds. The thermoplastic ABS housing resists impact and general wear in indoor commercial environments.

Once installed, the adjustable heads can be repositioned as needed to account for changes in space layout or obstructions. The internal battery maintains charge during normal building power operation and activates automatically when utility power is lost.

How This Fixture Is Commonly Used

After installation, the primary interaction with this fixture is positioning the two LED heads. Each head rotates and tilts independently, allowing you to aim light toward floor paths, doorways, or obstacles that need to remain visible during an outage. This adjustment is typically done once during commissioning and revisited only if the space changes.

The fixture operates passively under normal conditions, charging its internal battery while connected to building power. During a power loss event, the unit switches to battery operation automatically and runs for up to 90 minutes. No manual activation is required.
