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 300 watt LED high temperature light is a UFO-form fixture built for continuous operation in high-heat industrial environments. It produces 39,000 lumens and is available in 4000K or 5000K color temperature.
The fixture operates in ambient temperatures from -40F to 194F. It is configured for applications where standard high bay fixtures may not tolerate elevated operating temperatures.
Core Performance and Output
The fixture delivers 39,000 lumens at 130 lumens per watt. It is listed as a replacement for 1000 watt metal halide lighting.
Available beam angles include 10 degrees, 25 degrees, 40 degrees, 90 degrees, and 120 degrees. Narrow optics concentrate output over longer distances, while wider optics support broader coverage patterns.
Input voltage options are 100V-277V or 347V-480V at 50/60 Hz. Power factor is greater than 0.95 and THD is less than 15 percent. The 39,000-lumen output can be excessive at lower mounting heights without an appropriate optical and layout review.
Adjustability and Control Options
This fixture is offered in 4000K or 5000K color temperature configurations. Beam angle selection is available from 10 degrees through 120 degrees.
The fixture is not dimmable. Lighting levels must be established through fixture quantity, mounting location, beam angle, and layout.
Longevity and Reliability
Rated life is 70,000 hours. The operating temperature range is -40F to 194F.
The aluminum alloy housing and polycarbonate lens support use in elevated-temperature conditions. IP66 protection is provided for the fixture enclosure.
Build Quality and Physical Characteristics
The fixture uses a gray aluminum alloy housing with a polycarbonate lens. Overall dimensions are 19.6 x 16.53 x 8.65 inches.
Fixture weight is 38.3 pounds. Eye-hook and pendant mounting options are available, and the mounting structure must support the fixture weight.
Where This Product Fits Best
This high temperature fixture fits industrial locations where elevated ambient temperature is part of normal operation. Its 194F maximum operating temperature supports demanding heat-related lighting conditions.
- steel mill lighting
- industrial furnace area lighting
- power plant and energy site lighting
- nuclear facility lighting
- foundry lighting
- kiln lighting
- glass manufacturing lighting
These applications can involve heat, dust, and long operating schedules. IP66 construction and the stated operating temperature range should be matched to actual site conditions.
Installation and Long-Term Use
Eye-hook mounting supports suspended installation, while pendant mounting provides a fixed hanging arrangement. The selected mounting method must accommodate the 38.3-pound fixture weight.
Voltage must match either the 100V-277V or 347V-480V fixture configuration. This fixture is non-dimming, so controls requiring dimming are not supported.
How This Fixture Is Commonly Used
In steel mill lighting, industrial furnace area lighting, and foundry lighting, the fixture is positioned at mounting heights that allow the selected optic to direct output to the required work area. Narrow beam angles are used where concentrated output is needed, while wider angles support broader layouts.
For power plant and energy site lighting, nuclear facility lighting, kiln lighting, and glass manufacturing lighting, layout planning accounts for mounting height, equipment placement, target light levels, and heat exposure. Higher output can reduce fixture count, but beam selection and spacing still control uniformity and glare.
Safety, Certifications, and Warranty
This fixture is ETL certified. It carries an IP66 rating.
The warranty period is 5 years. The fixture is rated for operation from -40F to 194F.
