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 450 watt LED high temperature light delivers 58,500 lumens at 5000K for demanding high-heat lighting conditions. It is designed for continuous operation in ambient temperatures from -40F to 176F.
The fixture is used for high temperature facility lighting, industrial furnace area lighting, steel mill lighting, foundry lighting, power plant and energy site lighting, and nuclear facility lighting. Its 90 degree standard beam and optional narrow or wide optics support different layout requirements.
Core Performance and Output
The fixture produces 58,500 lumens from 450 watts, delivering 130 lumens per watt. It operates on either 100V-277V or 277V-480V, with a 0.95 power factor, 50/60 Hz operation, and THD of 20% maximum.
A 90 degree beam angle is standard. Optional 30 degree, 110 degree, and 150 degree beam angles allow the fixture to be matched to concentrated, general, or broad-area distributions.
The 30 degree optic provides a more concentrated distribution, while the 150 degree option spreads output across a wider area. The 58,500-lumen output can be excessive where mounting positions are low or where close fixture spacing is required.
Adjustability and Control Options
This fixture is non-dimming. Control systems requiring dimming should not be specified for this configuration.
Light distribution can be adjusted through the available 30 degree, 90 degree, 110 degree, and 150 degree optics. The selected optic should match the mounting position and required distribution pattern.
Longevity and Reliability
The LED system is rated for 100,000 L70 hours. This rating supports long service intervals in locations where fixture access may be difficult.
Integrated 12kV surge protection addresses electrical surge exposure. The fixture is rated for operation from -40F to 176F.
Build Quality and Physical Characteristics
The housing is die-cast aluminum with a gray finish. A polycarbonate lens protects the optical system.
The fixture is IP66 rated and IK10 rated. It measures 38.0 x 14.4 x 9.6 inches and weighs 61.7 pounds.
Eye-hook and trunnion mounting are available. The mounting structure and attachment method must support the fixture weight and selected mounting arrangement.
Where This Product Fits Best
This fixture fits high-heat operating areas where high output, elevated ambient-temperature capability, and protected construction are required. It is intended for the specialized high temperature lighting applications listed below.
- power plant and energy site lighting
- industrial furnace area lighting
- steel mill lighting and foundry lighting
- nuclear facility lighting
- boiler room lighting
- heat treatment facility lighting
The IP66 enclosure, IK10 impact rating, die-cast aluminum housing, and 176F maximum operating temperature support use in demanding high-temperature conditions. Final placement still depends on actual ambient temperature at the fixture location.
Installation and Long-Term Use
Eye-hook mounting is suited to suspended fixture positions, while trunnion mounting provides a fixed directional mounting method. The selected voltage version must match the available electrical system.
At 61.7 pounds, this fixture requires a mounting point capable of carrying the fixture and its installation hardware. Aim and optic selection should be completed before final trunnion tightening.
Long-term performance depends on maintaining fixture operation within the -40F to 176F temperature range. The non-dimming configuration should be accounted for before connecting controls.
How This Fixture Is Commonly Used
In power plant and energy site lighting, steel mill lighting, and foundry lighting, fixtures are positioned from available structural mounting locations to direct output toward the required work areas. Eye-hook mounting is used where a suspended position is available, while trunnion mounting is used where aiming is required.
For industrial furnace area lighting, boiler room lighting, and heat treatment facility lighting, layouts account for the heat level at the fixture location and the required beam distribution. Wider optics support broader distribution patterns, while narrow optics concentrate light from the available mounting position.
Spacing varies with the selected optic, mounting position, and required light levels. Higher output can reduce fixture count, but close spacing can create excessive light levels.
Safety, Certifications, and Warranty
This fixture is ETL certified.
It is IP66 rated, IK10 rated, and includes 12kV surge protection. The warranty is 5 years.
