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 80-watt round explosion proof LED light produces 11,200 lumens at 5000K. It is designed for hazardous location lighting where Class I, II, III, ATEX, IECEx, wet-location, marine, and impact ratings are required.
The fixture replaces a 250-watt metal halide fixture and is available in 100V-277V or 277V-480V configurations. Yoke and 3/4 inch NPT pendant mounting support fixed-position installation.
Core Performance and Output
The fixture delivers 11,200 lumens from 80 watts, with an efficacy of 140 lumens per watt. Color temperature is 5000K with a CRI of 70+.
A 120 degree beam angle is standard. Optional 40 degree, 60 degree, and 90 degree beam angles allow the distribution to match the mounting position and layout.
Input voltage is 100V-277V or 277V-480V, depending on configuration. Power factor is greater than 0.95, THD is less than 10%, and operating frequency is 50-60Hz. The 120 degree distribution can place excessive light outside a focused work area when installed at lower mounting heights.
Adjustability and Control Options
This fixture supports 1-10V dimming. Dimming controls must match the selected voltage configuration and the 1-10V control input.
Beam angle selection is fixed at installation. The standard 120 degree lens and optional 40 degree, 60 degree, and 90 degree optics should be selected around the planned mounting height and lighting layout.
Longevity and Reliability
Rated life is 50,000 hours at L70. The fixture includes 10kV surge protection.
Operating temperature range is -40°F to 140°F. The warranty is five years.
Build Quality and Physical Characteristics
The housing is copper-free aluminum with a gray finish. A tempered glass lens protects the optical assembly.
The fixture is IP66 rated and IK10 rated. Dimensions are 10.63 by 10.47 inches, and fixture weight is 9.7 pounds.
Where This Product Fits Best
This fixture fits classified and hazardous operating areas where the required electrical classification, environmental rating, and mounting arrangement match the fixture specifications.
- hazardous location lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- refinery lighting
- marine environment lighting
Its IP66 rating, IK10 rating, wet-location listing, marine listing, and -40°F to 140°F operating range support demanding environmental conditions within the stated certifications and markings.
Installation and Long-Term Use
The fixture mounts by yoke or 3/4 inch NPT pendant. The 9.7-pound fixture weight and selected mounting method should be considered when preparing the mounting structure.
Voltage configuration must match the available supply voltage. The yoke allows fixed directional positioning, while the pendant mount positions the round fixture below the mounting point.
Long-term service planning should account for the tempered glass lens, housing access, control wiring where 1-10V dimming is used, and the selected optical distribution.
How This Fixture Is Commonly Used
In hazardous location lighting, paint booth lighting, and chemical processing facility lighting, the fixture is positioned around the available mounting height, equipment layout, and required light distribution. Yoke mounting is used where fixture direction needs to be set during installation, while pendant mounting places the fixture below the structure.
Oil and gas facility lighting, refinery lighting, and marine environment lighting layouts use the selected beam angle to control where the 11,200-lumen output is directed. Higher output can reduce fixture count, but beam angle and mounting height still affect uniformity and glare.
