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 150 watt LED high temperature light is a UFO high bay fixture built for high-heat industrial lighting environments. It produces 19,500 lumens at 5000K and operates on either 100V-277V or 277V-480V power.
The fixture is rated for operation from -40F to 176F. It is used where elevated ambient temperatures, dust exposure, moisture, and physical impact require a more durable high bay construction.
Core Performance and Output
This fixture delivers 19,500 lumens at 130 lumens per watt. The 110 degree standard beam angle provides broad distribution, with 30 degree, 90 degree, and 150 degree optical options available for different layout requirements.
It operates at 50/60 Hz with a 0.95 power factor and 20% maximum THD. The fixture includes 12kV surge protection.
The 19,500-lumen output can be excessive at lower mounting heights. Narrower optics require more deliberate aiming and layout planning to maintain coverage between fixtures.
Adjustability and Control Options
This fixture is non-dimming. Output remains fixed at the rated 150 watt operating level.
Voltage configuration is available in 100V-277V or 277V-480V. Confirm the available supply voltage before installation.
Longevity and Reliability
The LED system is rated for 100,000 hours at L70. This rating supports long operating periods in high temperature facility lighting where fixture access may be limited.
The fixture includes 12kV surge protection for electrical disturbance resistance. Long-term performance remains dependent on operating within the -40F to 176F ambient temperature range.
Build Quality and Physical Characteristics
The fixture uses a die-cast aluminum housing with a gray finish. A polycarbonate lens protects the optical system.
It carries IP66 and IK10 ratings. The fixture measures 15.8 inches long by 14.4 inches wide by 9.6 inches high and weighs 20.75 pounds.
Where This Product Fits Best
This fixture fits high-heat industrial areas that need high bay output and a 176F maximum operating temperature rating. Its construction supports locations exposed to dust, moisture, impact risk, and elevated ambient temperatures.
- power plant and energy site lighting
- nuclear facility lighting
- industrial furnace area lighting
- steel mill lighting
- foundry lighting
- boiler room lighting
IP66 protection, IK10 impact resistance, die-cast aluminum construction, and high-temperature operation are relevant environmental characteristics for these applications.
Installation and Long-Term Use
The fixture supports eye-hook or trunnion mounting. The mounting structure must support the 20.75-pound fixture weight and maintain secure attachment under operating conditions.
Eye-hook mounting suits suspended installation arrangements. Trunnion mounting supports fixed directional positioning where the selected beam angle requires aiming.
Installers should verify the voltage configuration, mounting method, and ambient temperature before commissioning. The fixture is non-dimming, so control planning should account for fixed output.
How This Fixture Is Commonly Used
In power plant and energy site lighting, nuclear facility lighting, steel mill lighting, and foundry lighting, fixtures are positioned at mounting heights that support the selected optic and required working-area distribution. Eye-hook mounting is used for suspended layouts, while trunnion mounting is used where directional aiming is required.
Industrial furnace area lighting, boiler room lighting, and kiln lighting layouts typically account for high-temperature exposure and the physical location of equipment. Fixture placement must keep the ambient operating condition within the rated -40F to 176F range.
Spacing varies with mounting height, beam angle, and required light distribution. Higher output can reduce fixture count, but optic selection affects uniformity across the layout.
Safety, Certifications, and Warranty
This fixture is ETL listed.
It is rated IP66 and IK10.
The warranty is 5 years.
