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 50-watt LED high temperature light is designed for lighting areas exposed to sustained elevated ambient temperatures. It produces 7,500 lumens at 5000K and operates from 100-277V.
The fixture is rated for operation from -40F to 392F. Its pendant mount, aluminum alloy housing, tempered glass lens, and IP66 rating support installation in demanding high temperature facility lighting environments.
This model replaces a 250-watt metal halide fixture where the existing installation requires a high temperature-rated LED fixture.
Core Performance and Output
The fixture delivers 7,500 lumens at 150 lumens per watt. The 5000K color temperature and 75+ CRI provide a cool white output for industrial work areas.
A standard 120-degree beam angle distributes light broadly below the pendant-mounted fixture. The wide distribution is suited to open layouts, but fixture placement must account for mounting height and required light levels.
Electrical operation is 100-277V at 50/60 Hz. Power factor is greater than 0.95 and total harmonic distortion is less than 15%.
At lower mounting heights, 7,500 lumens can create excessive brightness directly below the fixture. At greater mounting heights, the broad beam requires a layout review to maintain uniformity.
Adjustability and Control Options
This fixture is not dimmable. It operates at its rated 50-watt input without a dimming control option.
The product data identifies a standard 120-degree beam angle. No alternate optics or adjustable beam distribution are specified.
Longevity and Reliability
Rated life is 100,000 hours to L70. This rating identifies the point at which light output is expected to remain at 70% of initial output.
The operating temperature range is -40F to 392F. This temperature rating is a primary selection factor for installations near process heat.
Integrated 6kV surge protection provides electrical transient protection. Long-term performance also depends on maintaining the fixture within its stated voltage and temperature limits.
Build Quality and Physical Characteristics
The housing is aluminum alloy with a silver finish. A tempered glass lens protects the optical assembly.
The fixture is IP66 rated. It measures 12.2 x 16.9 x 2.3 inches and weighs 15.4 pounds.
Pendant mounting places the fixture below the supporting structure. The mounting point and support method must carry the fixture weight.
Where This Product Fits Best
This high temperature fixture fits industrial locations where ambient heat exceeds the limits of standard lighting equipment. Its 392F maximum operating temperature supports installations associated with process heat and energy operations.
- 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
IP66 construction and the tempered glass lens support use in areas requiring protected fixture construction. Final placement must keep the fixture within its -40F to 392F operating range.
Installation and Long-Term Use
The fixture uses pendant mounting and requires a secure overhead support location. Confirm fixture weight, mounting hardware, supply voltage, and conductor routing before installation.
Its 100-277V operating range accommodates common commercial and industrial voltage systems within that range. The fixture is non-dimmable, so control plans must use switched operation rather than dimming.
For long-term use, keep the lens clean and inspect the housing, pendant connection, and electrical connections during routine maintenance. Do not operate the fixture outside its stated temperature range.
How This Fixture Is Commonly Used
In power plant and energy site lighting, industrial furnace area lighting, steel mill lighting, and foundry lighting, the fixture is pendant-mounted from available overhead structure. Mounting height is determined by the process area, overhead support location, and required light distribution.
Layouts commonly use a repeated pendant pattern across the area being lit. Spacing varies with mounting height, target light levels, and the 120-degree beam distribution.
For nuclear facility lighting, boiler room lighting, and heat treatment facility lighting, fixture placement must account for the local ambient temperature at the installed fixture location. Higher mounting locations may reduce heat exposure but change light distribution on the work area.
Safety, Certifications, and Warranty
This fixture is ETL listed.
The fixture is IP66 rated and includes 6kV surge protection.
Warranty coverage is 2 years.
Frequently Asked Questions
Q: What is the maximum operating temperature for this fixture?
A: The fixture is rated to operate from -40F to 392F.
Q: Does this high temperature light support dimming?
A: No. The fixture is not dimmable.
Q: What mounting method does this fixture use?
A: The fixture uses pendant mounting.
Q: What light distribution does the fixture provide?
A: The standard beam angle is 120 degrees.
Q: What should be reviewed when planning the fixture layout?
A: Mounting height, target light levels, and the 120-degree beam distribution affect layout planning. The supplied product data does not establish a specific spacing value.
Application Questions and Clarification
Q: Is this fixture appropriate for industrial furnace area lighting?
A: The fixture is rated for industrial furnace area lighting and has an operating temperature range of -40F to 392F. The ambient temperature at the installed fixture location must remain within that range.
Q: What should be confirmed for power plant and energy site lighting?
A: Confirm that the available supply voltage is within the fixture’s 100-277V operating range and that the fixture location remains within the stated operating temperature range.
Q: What should be considered for pendant mounting in steel mill lighting or foundry lighting?
A: Confirm that the overhead support and mounting method can carry the 15.4-pound fixture. Placement must also account for the required light distribution and local ambient temperature.
