Product Overview
The 300 Watt Square Explosion Proof LED Light is engineered for hazardous location lighting, delivering robust performance in environments where safety is paramount. With a lumen output of 42,000 lumens at a color temperature of 5000K, this fixture is suitable for replacing traditional 1000 Watt metal halide lamps. Designed for use in Class I, Division 2 areas, it is ideal for applications such as paint booth lighting and chemical processing facilities.
This fixture operates efficiently across a wide voltage range of 100V-277V or 277V-480V, making it versatile for various industrial settings. Its construction includes a tempered glass lens and a durable copper-free aluminum housing, ensuring longevity and reliability in demanding conditions. The fixture's IP66 and IK10 ratings confirm its suitability for wet and impact-prone environments.
Core Performance and Output
With an output of 42,000 lumens and an efficacy of 140 lumens per watt, this explosion-proof LED light provides high-intensity illumination suitable for large, open spaces. The standard beam angle of 120° ensures broad coverage, while optional beam angles of 40°, 60°, and 90° offer flexibility for targeted lighting needs. The fixture's power factor exceeds 0.95, and its total harmonic distortion is less than 10%, ensuring efficient electrical performance.
While the fixture is designed for high-output applications, care should be taken to avoid excessive glare in low-ceiling installations. Additionally, uniformity may decrease at higher mounting heights, necessitating careful planning for optimal light distribution.
Adjustability and Control Options
This fixture supports 1-10V dimming, allowing for adjustable light levels to suit specific task requirements or energy-saving goals. The dimming capability provides flexibility in environments where varying light intensities are needed, such as in paint booths or chemical processing areas.
Mounting options include yoke or 3/4 inch NPT pendant, offering adaptability to different installation scenarios. These options facilitate secure and stable mounting in environments where vibration or movement may be a concern.
Longevity and Reliability
Designed for a lifespan of 50,000 hours (L70), this explosion-proof LED light minimizes maintenance requirements and ensures long-term reliability. The fixture's robust construction, including a copper-free aluminum housing and tempered glass lens, contributes to its durability in harsh environments.
With a surge protection rating of 10kV, the fixture is well-protected against electrical surges, further enhancing its reliability in industrial settings where power fluctuations may occur.
Build Quality and Physical Characteristics
The fixture's housing is constructed from copper-free aluminum, providing excellent resistance to corrosion and ensuring longevity in marine or chemical environments. Its IP66 rating confirms its suitability for wet locations, while the IK10 rating indicates high impact resistance.
Operating temperatures range from -40°F to 122°F, allowing for use in a variety of climates and conditions. The fixture's gray color and compact dimensions (16.6 x 11.8 x 8.3 inches) make it a discreet yet powerful lighting solution for hazardous locations.
