300 Watt LED High Temperature Light | 39000 Lumens | 5000K | 100V-277V or 277V-480V | Rated to 176F

Product Overview

This 300 watt LED high temperature fixture delivers 39,000 lumens at 5000K color temperature and operates in ambient conditions up to 176°F. The fixture replaces 1000 watt metal halide systems and is built with a die-cast aluminum housing and oversized heat sink designed for sustained performance in elevated temperature environments.

Voltage options include 100V-277V and 277V-480V configurations. The fixture is 3G vibration-tested and carries an IP66 rating for protection against dust ingress and high-pressure water jets, along with an IK10 rating for resistance to heavy physical impact. A polycarbonate lens protects the optics.

Mounting is available via eye-hook or trunnion. The standard beam angle is 90 degrees, with optional 30, 110, and 140 degree optics available. Dimming is available in 1-10V configuration on select versions. The fixture weighs 42.55 pounds and measures 26.9 x 14.4 x 9.6 inches.

Where This Product Fits Best

This fixture is intended for facilities where ambient temperatures reach or sustain levels up to 176°F. Foundries, steel mills, glass plants, heat treatment areas, and similar industrial spaces with radiant or process-generated heat are the primary application. The 3G vibration rating makes this fixture suitable for locations near heavy machinery, presses, or conveyors where structural vibration is transmitted to mounting points.

The IP66 rating allows installation in spaces with aggressive washdown procedures, airborne particulates, or outdoor exposure. IK10 impact resistance supports use in areas where fixtures may be struck by equipment, material handling activity, or debris. The extended operating temperature range down to -40°F also allows use in unheated facilities or cold storage transition zones.

Performance and Functional Considerations

At 130 lumens per watt, this fixture produces 39,000 lumens from 300 watts. The 5000K color temperature provides a daylight-equivalent output suitable for task visibility in industrial environments. CRI is rated at 70+, which is standard for general industrial use but may not be appropriate for color-critical inspection or finishing work.

The 1-10V dimming option allows output adjustment when connected to compatible controls. Fixtures without dimming operate at full output only. Power factor is rated at .95 with a maximum THD of 20%, supporting stable operation on commercial and industrial electrical systems.

Rated lifespan is 100,000 hours at L70, meaning the fixture will maintain at least 70% of initial lumen output at that point. Surge protection is rated at 12kV, which provides a buffer against transient voltage events common in facilities with large inductive loads.

Installation and Long-Term Use

The fixture mounts via eye-hook for pendant or chain suspension, or via trunnion for wall, ceiling, or beam mounting with adjustable aim. At 42.55 pounds, this is a heavy fixture that requires secure structural attachment and may require two-person handling during installation.

Beam angle selection should be confirmed at time of specification. The standard 90 degree optic works for general area coverage. The 30 degree option concentrates output for higher mounting heights or narrow target areas. The 110 and 140 degree options spread light wider for lower mounts or broader coverage needs.

The die-cast aluminum housing and oversized heat sink are designed to dissipate heat in high ambient conditions without derating. The fixture is ETL listed. The 5-year warranty covers manufacturing and material defects under normal operating conditions within the stated temperature range.

How This Fixture Is Commonly Used

Facilities use this fixture in areas where standard LED high bays would overheat and fail prematurely. The 176°F maximum ambient rating allows installation directly above heat-generating processes, in enclosed mezzanines with trapped heat, or in buildings without climate control during summer peak conditions.

The trunnion mount is often used when aiming the fixture toward a specific work zone or when mounting on angled structural members. Eye-hook mounting is typical for straight-down pendant installations in open bays. Beam angle selection at specification time determines how light is distributed once the fixture is installed.

Where dimming is installed, the 1-10V signal allows integration with building automation or manual dimmer controls to reduce output during unoccupied periods or shift changes. Facilities operating both 277V and 480V systems will need to confirm voltage at time of specification to match the fixture to the available circuit.

Safety, Certifications, and Warranty

This fixture is ETL listed. The IP66 rating means the fixture is fully protected against dust ingress and can withstand high-pressure water jets from any direction. The IK10 rating means the fixture can withstand impacts equivalent to significant physical force without damage to housing or optics.

Surge protection is rated at 12kV. The 3G vibration rating confirms the fixture has been tested and approved for use in environments with continuous mechanical vibration. We provide a 5-year warranty on this fixture.
