Product Overview

This 45 watt LED barn light delivers 6300 lumens at 5000K color temperature, replacing 150 watt metal halide fixtures. The built-in dusk-to-dawn photocell eliminates manual switching by automatically turning the fixture on at dark and off at daylight.

The die-cast aluminum housing resists rust and corrosion in outdoor environments. A polycarbonate lens distributes light evenly across a 120-degree beam angle while limiting glare. The fixture operates on 100-277V input and supports 0-10V dimming.

At 140 lumens per watt, this fixture produces substantial output from a compact unit measuring 12.26 inches long by 7.6 inches wide by 4.45 inches high and weighing 2.65 pounds.

Where This Product Fits Best

This barn light is built for outdoor security and area lighting where automatic dusk-to-dawn operation is needed. The IP65 rating means the fixture is protected against dust ingress and water jets from any direction, making it suitable for exposed mounting locations subject to rain, snow, and washdown.

The 5000K color temperature provides bright, neutral white light appropriate for security applications, parking areas, building perimeters, loading areas, and entryways. The 120-degree beam angle creates broad coverage directly below and around the fixture.

With 100-277V compatibility, the fixture works across standard commercial voltage systems without requiring a transformer or voltage-specific selection.

Performance and Functional Considerations

The 6300 lumen output from 45 watts positions this fixture as a direct replacement for 150 watt metal halide barn lights. The 70,000-hour rated lifespan significantly extends service intervals compared to HID sources.

CRI is rated at 70+, which is standard for security and area lighting applications where color accuracy is not critical. Power factor exceeds 0.98 and total harmonic distortion is below 20%, indicating clean electrical load characteristics.

The 0-10V dimming capability allows output reduction when connected to a compatible dimmer or control system. The built-in photocell operates independently of any dimming function, controlling on/off switching based on ambient light levels.

Installation and Long-Term Use

The fixture accepts surface mounting directly to a wall or junction box, or arm mounting using a compatible mounting arm. The silver finish blends with most exterior surfaces and hardware.

Die-cast aluminum construction and IP65-rated sealing support long-term exterior exposure. The photocell is integrated into the housing, so no separate sensor installation or wiring is required.

At 2.65 pounds, the fixture places minimal load on mounting surfaces and arms. The 50-60Hz frequency rating confirms compatibility with standard AC power systems.

How This Fixture Is Commonly Used

Once installed, this fixture operates hands-off. The photocell turns the light on automatically when ambient light drops at dusk and turns it off at dawn. No timer programming or manual switching is involved in daily operation.

If the fixture is connected to a 0-10V dimmer, output can be adjusted for specific brightness requirements or to coordinate with other lighting in the area. Without a dimmer connected, the fixture runs at full output whenever the photocell activates it.

The broad 120-degree beam angle means light spreads outward from the fixture rather than concentrating in a narrow spot. This makes it practical for general area coverage rather than accent or spot applications.
