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.

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 adjustable LED UFO high bay provides 240W, 270W, or 310W operation with selectable 4000K or 5000K color temperature. It is configured for high-output indoor lighting where a compact round fixture and broad 110 degree distribution are required.

The fixture produces 34,800 to 45,000 lumens and can replace 400W or 1000W metal halide fixtures where lighting layouts and target light levels support the change. Warehouse lighting and manufacturing facility lighting are common deployment contexts.

Core Performance and Output

Output is selectable at 34,800 lumens, 39,150 lumens, or 45,000 lumens, depending on the 240W, 270W, or 310W setting. Fixture efficacy is 145 lumens per watt with a minimum 80 CRI.

The standard 110 degree beam angle provides broad distribution from the polycarbonate lens. The fixture operates on 100-277V, 50/60Hz power, with a power factor of 0.90 and THD of 20% maximum.

The 45,000-lumen setting can produce excessive light at lower mounting heights. Higher mounting heights and wider layouts require a layout review to confirm uniformity with the 110 degree distribution.

Adjustability and Control Options

Wattage is adjustable between 240W, 270W, and 310W. Color temperature is adjustable between 4000K and 5000K.

0-10V dimming is included. A motion sensor is available for projects requiring occupancy-based control.

Longevity and Reliability

The LED system is rated for 50,000 L70 hours. This rating identifies the point at which light output is expected to remain at 70 percent of initial output.

The fixture includes 4kV surge protection and operates from -40F to 113F. These operating limits should be reviewed against actual site conditions.

Build Quality and Physical Characteristics

The housing is die-cast aluminum with a black finish. The fixture uses a polycarbonate lens and carries IP65 and IK10 ratings.

Fixture dimensions are 14 inches wide by 11 inches high, with a weight of 11 pounds. It includes a 5-foot power cord and an 8-inch dimming cord.

Where This Product Fits Best

This UFO high bay fits high-output indoor lighting layouts where broad fixture distribution, selectable wattage, and 100-277V operation align with the facility electrical system.

  • warehouse lighting
  • distribution center lighting
  • manufacturing facility lighting
  • gymnasium lighting
  • aircraft hangar lighting
  • indoor sports facility lighting

Its IP65 and IK10 ratings support installations where fixture durability is a project requirement. The selectable output settings allow the fixture output to be matched to the lighting layout.

Installation and Long-Term Use

Hook and pendant mounting are standard. Surface mounting is optional. Mounting selection should account for the fixture weight, cord routing, and available support structure.

Mounting height affects light level, distribution, and glare control. The supplied data does not establish a fixed mounting height or spacing value, so final layout decisions should be based on project lighting requirements.

How This Fixture Is Commonly Used

In warehouse lighting, distribution center lighting, and manufacturing facility lighting, the fixture is commonly arranged in rows or grid patterns to maintain coverage across the layout. Mounting height and selected wattage determine the final fixture arrangement.

For gymnasium lighting, aircraft hangar lighting, and indoor sports facility lighting, the broad 110 degree beam angle supports wide-area distribution. Higher output can reduce fixture count, but may require added glare and uniformity review.

Safety, Certifications, and Warranty

UL listed. DLC Premium listed.

The fixture includes a 5-year warranty. IP65, IK10, and 4kV surge protection are included.
