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.

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

Room / Layout Condition: This is a simplified room utilization factor. It accounts for room 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.

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/layout condition, 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.

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 for environments where high ambient temperatures are a constant challenge. Designed to deliver 39,000 lumens at a color temperature of 5000K, this fixture is suitable for demanding applications such as power plants and nuclear facilities. With a robust aluminum alloy housing and polycarbonate lens, it is built to withstand temperatures up to 194°F, making it an ideal replacement for 1000 Watt Metal Halide fixtures in high-temperature settings.

Core Performance and Output

This LED high bay fixture offers an impressive output of 39,000 lumens, achieving an efficiency of 130 lumens per watt. It operates on a voltage range of 100V-277V or 347V-480V, ensuring compatibility with various electrical systems. The fixture provides multiple beam angle options, including 10°, 25°, 40°, 90°, and 120°, allowing for tailored light distribution. While it excels in high-temperature environments, care should be taken to avoid excessive output at low mounting heights, which could lead to glare.

Adjustability and Control Options

The fixture is designed for straightforward installation with eye-hook or pendant mounting options. Although it does not feature dimming capabilities, the variety of beam angles available allows for some degree of customization in light distribution. This flexibility supports precise lighting layouts in complex industrial settings.
