Product Overview
This 450 Watt LED high temperature light delivers 58,500 lumens at 5000K. It is designed for use in environments with ambient temperatures up to 176°F (80°C).
The fixture is available in two voltage options: 100V-277V or 277V-480V. It is built with a die-cast aluminum housing and a polycarbonate lens.
Standard beam angle is 90°, with optional 30°, 110°, or 150° optics. The fixture color is gray. It operates at 50/60 Hz with a power factor of 0.95 and a maximum THD of 20%.
This fixture is intended as a replacement for 1000 Watt metal halide systems. It is non-dimming and has a rated lifespan of 100,000 (L70) hours.
Where This Product Fits Best
This fixture is suitable for high bay and industrial applications where high ambient temperatures are present. It is rated for continuous operation in environments up to 176°F.
Common installation locations include foundries, steel mills, glass manufacturing, and other facilities with elevated heat exposure. The IP66 rating allows use in areas exposed to dust and strong water jets.
The IK10 rating supports use in locations where fixtures may be subject to mechanical impact. The fixture?s robust construction and surge protection make it appropriate for demanding industrial settings.
Mounting options include eye-hook and trunnion, supporting both suspended and surface installations.
Performance and Functional Considerations
The fixture outputs 58,500 lumens at 130 lumens per watt, providing high light levels for large, high-ceiling spaces. The 5000K color temperature delivers a neutral white light suitable for task visibility.
Beam angle selection allows adjustment of light distribution to match the application. The standard 90° optic is suitable for most high bay layouts, while 30°, 110°, and 150° options are available for more focused or wider coverage as needed.
The fixture operates on either 100V-277V or 277V-480V input, supporting compatibility with a range of electrical systems. It is non-dimming and does not support integrated dimming controls.
Surge protection is rated at 12kV, supporting operation in facilities with electrical disturbances or heavy equipment.
Installation and Long-Term Use
The fixture measures 38.0 x 14.4 x 9.6 inches and weighs 61.7 lbs. Installation requires appropriate support for the fixture?s weight and size.
Eye-hook mounting supports suspension from ceiling structures, while the trunnion option allows surface or wall mounting. Both methods are suitable for industrial environments.
The die-cast aluminum housing and polycarbonate lens are designed for durability in harsh conditions. The IP66 rating allows for installation in areas exposed to dust and water spray.
With a rated lifespan of 100,000 hours (L70), the fixture is intended for long-term, low-maintenance operation in continuous-use environments.
How This Fixture Is Commonly Used
After installation, this fixture provides consistent, high-output lighting in high-temperature environments. The 5000K color temperature supports clear visibility for production, inspection, and safety tasks.
Beam angle selection at the time of installation determines how the light is distributed in the space. Once installed, the fixture operates continuously without the need for dimming or adjustment.
The fixture?s robust housing and lens allow it to withstand impacts and exposure to dust or water jets. Maintenance requirements are minimal due to the long rated lifespan and solid-state construction.
Operators rely on this fixture for stable performance in areas where legacy metal halide systems would require frequent replacement or maintenance due to heat stress.
