Estimated average foot-candles are preliminary and should be verified with a lighting plan for project-critical applications.

Room Light Use Factor: Suggested starting points: open warehouse 0.85–0.90, clean light-colored space 0.75–0.85, typical warehouse 0.65–0.75, racked or obstructed space 0.50–0.65, dark or complex space 0.40–0.55.

Beam Angle Note: When beam angle data is available, this estimator uses the selected beam angle to adjust the visual light spread pattern. Narrower beams show stronger on-center intensity and faster edge falloff; wider beams show smoother spread. This is an approximate model, not a true IES point-by-point calculation.

Preliminary Estimate Only: This estimator is intended for simple square or rectangular spaces. Actual light levels may vary based on fixture optics, mounting conditions, ceiling height, surface reflectance, obstructions, controls, voltage, installation conditions, and site-specific requirements.

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

The 300 Watt UFO High Bay is designed for high-efficiency lighting in large indoor spaces. Delivering 45,000 lumens at a color temperature of 5000K, this fixture is suitable for replacing traditional 1000 Watt metal halide lights. It operates on a versatile voltage range of 100-277V, 277-480V, or 127-300VDC, making it adaptable to various electrical systems. This fixture is commonly used in environments such as warehouses and manufacturing facilities, where high lumen output and reliability are essential.

With its UL and DLC Premium listings, the fixture meets stringent performance and safety standards. The IP65 and IK08 ratings ensure it can withstand dust, water, and impact, making it suitable for demanding industrial settings. The standard eye-hook mounting allows for straightforward installation, with optional pendant or surface mount configurations available for added flexibility.

Core Performance and Output

This UFO High Bay fixture provides a high lumen output of 45,000 lumens, achieving an efficiency of 150 lumens per watt. It features a 120° beam angle, ensuring broad and even light distribution across large areas. The fixture's electrical performance is robust, with a power factor of 0.90 and a maximum total harmonic distortion (THD) of 20%, ensuring stable operation.

While the fixture is designed for high ceilings, excessive output may occur at lower mounting heights, potentially leading to glare. For optimal performance, consider the mounting height and space layout to ensure uniform light distribution and minimize any potential for reduced uniformity at higher mounting heights.

Adjustability and Control Options

The 300 Watt UFO High Bay includes 1-10V dimming capabilities, allowing for adjustable light levels to suit different tasks and energy-saving needs. This feature provides flexibility in controlling the lighting environment, enhancing both comfort and efficiency.
