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 light use factor to generate a preliminary lighting layout.

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.

Photometry / Simulation Note: When usable IES photometry is available for the selected fixture, this estimator uses the fixture’s IES candela data to improve the visual floor-level light distribution. When IES photometry is not available, the estimator uses a simulated beam model based on lumens, mounting height, room light use factor, light loss factor, and beam angle.

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.

Need Verified Light Levels?

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 LED High Temperature Light is engineered to perform in environments with elevated temperatures, making it suitable for industrial applications such as power plants and nuclear facilities. This fixture delivers 39,000 lumens at a color temperature of 5000K, ensuring bright and clear illumination. Designed for high-temperature areas, it operates efficiently within a temperature range of -40°F to 194°F, providing reliable lighting in challenging conditions.

Core Performance and Output

This LED high bay fixture offers an impressive output of 39,000 lumens with an efficacy of 130 lumens per watt. It is designed to replace traditional 1000 Watt metal halide fixtures, providing significant energy savings. The fixture supports multiple beam angles, including 10°, 25°, 40°, 90°, and 120°, allowing for tailored light distribution based on specific application needs. While it excels in high-temperature environments, care should be taken to avoid excessive output at low mounting heights, which may lead to increased glare.

Adjustability and Control Options

The fixture is available with eye-hook or pendant mounting options, providing flexibility in installation. Although it does not include dimming capabilities, the variety of beam angles allows for some control over light distribution. This adaptability ensures that the fixture can be optimized for different lighting requirements within high-temperature settings.

Longevity and Reliability

With a lifespan of 70,000 hours, this LED high bay light offers long-term reliability, reducing the need for frequent replacements. Its robust construction and high-quality components ensure consistent performance even in demanding environments. The fixture's power factor of greater than 0.95 and total harmonic distortion of less than 15% contribute to its efficient operation.
