450 Watt LED High Temperature Light | 58500 Lumens | 5000K | 100V-277V or 277V-480V | Rated to 176F
This 450W high-temperature LED high bay is well suited to power plants and nuclear facilities needing 58,500 lumens, 5000K light, and operation up to 176F. It replaces 1000W metal halide while delivering 130 lumens per watt. IP66, IK10, die-cast aluminum construction, and 12kV surge protection support demanding environments, while eye-hook or trunnion mounting and optional beam angles allow the fixture to suit different installation layouts.

Product Lighting Layout Estimator
Use this estimator to calculate approximate fixture count, spacing, and average foot-candles for a simple rectangular space using the selected LED fixture. Enter your room dimensions, mounting height, target foot-candles, light loss factor, and room/layout condition to generate a preliminary lighting layout. When IES photometry is available, workplane height and room reflectance controls are shown.
Project Inputs
Estimated Results
Estimated average foot-candles are preliminary and should be verified with a lighting plan for project-critical applications.
Room / Layout Condition: This field is used only when usable IES photometry is not available. In fallback mode, it acts as a simplified room utilization factor for reflectance, fixture distribution, racking, obstructions, and how much fixture light reaches the work area. Open / light-colored spaces use 0.90, typical warehouses or shops use 0.75, racked or obstructed spaces use 0.60, and dark or complex spaces use 0.45. When IES photometry is active, this field is hidden and the estimator uses the selected workplane height, LLF, and simplified reflectance adjustment instead.
Photometry / Simulation Note: When usable IES photometry is available for the selected fixture, this estimator uses the fixture’s IES candela data, selected workplane height, light loss factor, and simplified reflectance adjustment to estimate fixture count, average foot-candles, and visual light distribution. The reflectance adjustment is a conservative approximation and is not a full zonal-cavity, radiosity, or professional photometric room calculation. When IES photometry is not available, the estimator uses a simulated beam model based on lumens, mounting height, room/layout condition, light loss factor, and beam angle.
Preliminary Estimate Only: This estimator is intended for simple square or rectangular spaces and should be used as a planning aid, not a final photometric lighting plan. Actual light levels may vary based on fixture optics, selected IES file, mounting conditions, workplane height, ceiling height, surface reflectance, obstructions, controls, voltage, installation conditions, and site-specific requirements. Project-critical applications should be verified with a formal lighting plan.
This estimate is a starting point. Warehouses, industrial facilities, hazardous locations, sports areas, schools, healthcare spaces, public areas, and code-sensitive projects may require a reviewed lighting layout before purchase or installation.
Product Overview
This 450W LED high temperature light delivers 58,500 lumens at 5000K for demanding industrial areas with elevated ambient temperatures. It is designed to operate from -40 F to 176 F and is available in 100V-277V or 277V-480V configurations.
The fixture provides a 90 degree standard beam angle and uses a die-cast aluminum housing, polycarbonate lens, and gray finish. It is a replacement option for 1000W metal halide fixtures in high-temperature lighting installations.
Core Performance and Output
With 130 lumens per watt, this fixture produces high output from a 450W load. The 5000K color temperature and 70+ CRI provide a cool white industrial lighting appearance.
A 90 degree beam angle is standard. Optional 30 degree, 110 degree, and 150 degree beam angles allow the fixture to be selected for different lighting distributions.
Longevity and Reliability
The fixture is rated for 100,000 hours L70 life and includes 12kV surge protection. Its IP66 rating and IK10 impact rating support use in demanding industrial environments.
Build Quality and Physical Characteristics
The die-cast aluminum fixture measures 38.0 x 14.4 x 9.6 inches and weighs 61.7 lb. Eye-hook and trunnion mounting configurations are available.
