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 240 Watt Round LED UFO High Bay delivers 38,400 lumens at 5000K with a 120° beam angle. It is designed to replace 1000 Watt metal halide fixtures in high ceiling environments.
The fixture operates on either 100-277V or 277-480V input, supporting a wide range of commercial and industrial electrical systems. It features a die-cast aluminum housing finished in black and weighs 14.4 lbs.
The unit measures 15.75 by 7.9 inches and includes a 4-foot cord for connection. The fixture supports 1-10V dimming and has a power factor of 0.93 with a maximum THD of 20%.
Rated for 50,000 hours (L70), this high bay is built for long-term use in demanding environments.
Where This Product Fits Best
This fixture is suited for warehouses, manufacturing facilities, distribution centers, and other large indoor spaces with high ceilings where high-output lighting is required.
It is appropriate for locations seeking to upgrade from 1000 Watt metal halide systems to LED for improved efficiency and reduced maintenance.
The 5000K color temperature provides a daylight-white output, supporting visibility in task-oriented and general lighting applications.
Its IP65 rating allows use in areas exposed to dust and low-pressure water jets, such as industrial production floors and covered loading docks.
Performance and Functional Considerations
The fixture produces 160 lumens per watt, providing high efficacy for energy-conscious operations. The 120° beam angle delivers broad, even coverage suitable for open floor plans.
With a CRI of 80+, the fixture supports accurate color rendering for inspection, assembly, and general work environments.
1-10V dimming capability allows for integration with compatible dimming controls to adjust light levels as needed.
The fixture operates reliably in ambient temperatures from -22°F to 122°F, supporting use in both cold storage and high-heat industrial settings.
Installation and Long-Term Use
This high bay is designed for eye-hook mounting, which is standard for round UFO fixtures in commercial and industrial spaces. The 4-foot cord provides flexibility for connection to overhead power sources.
The die-cast aluminum housing offers durability and impact resistance for installation in active work areas. At 14.4 lbs, the fixture can be handled by a single installer using standard lift equipment.
IP65 protection allows for installation in locations where exposure to dust or water spray is expected, reducing concerns about fixture ingress over time.
The 50,000-hour rated lifespan supports long maintenance intervals, minimizing disruptions for lamp changes or fixture replacement.
How This Fixture Is Commonly Used
After installation, this fixture provides consistent, high-output illumination for large spaces. The 5000K color temperature supports visibility for detailed work and general movement throughout the facility.
Operators can adjust light levels using 1-10V dimming controls when integrated with compatible systems, allowing for energy management or adaptation to changing tasks.
The fixture’s broad beam angle reduces shadowing and helps maintain uniform light distribution across open areas. The IP65 rating means you can wash down floors or operate in dusty environments without concern for fixture damage.
Routine cleaning and inspection are straightforward due to the accessible housing and robust construction. The fixture’s weight and mounting method allow for straightforward removal and reinstallation if relocation is required.
