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.

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.

Estimator Version 2.9.20

Product Overview

This adjustable square explosion proof LED light provides 200W, 250W, or 300W output from a die-cast aluminum fixture. It is built for hazardous location lighting and explosion proof lighting where a high-output, wide-distribution fixture is required.

The fixture produces 35,000 to 52,500 lumens and can replace a 1000W metal halide fixture. Color temperature and wattage are adjustable before commissioning.

Core Performance and Output

Output is selectable at 200W, 250W, or 300W, producing 35,000, 43,750, or 52,500 lumens. Fixture efficacy is 175 lumens per watt with a CRI of 70+.

The standard 120 degree beam angle provides broad distribution through a tempered glass lens. Higher output settings can create excessive light levels at lower mounting heights, while higher mounting heights require layout review to maintain uniformity.

The fixture operates on 100-277V, 50/60Hz power and has a power factor above 0.95. Integrated 10kV surge protection supports electrical durability.

Adjustability and Control Options

Field-selectable wattage allows the fixture to operate at 200W, 250W, or 300W. Color temperature is selectable at 4000K, 5000K, or 6500K.

1-10V dimming is included. Dimming control wiring and control compatibility should be confirmed during project planning.

Longevity and Reliability

The rated service life is 100,000 hours at L70. The fixture is rated for operation from -40F to 122F.

Vibration performance is rated at 3G. The 10kV surge protection and sealed construction support long-term operation in demanding installations.

Build Quality and Physical Characteristics

The gray die-cast aluminum housing measures 16.54 x 11.81 x 14.89 inches and weighs 33.29 pounds. The fixture uses a tempered glass lens and has an IK08 impact rating.

IP66 and NEMA4X construction protect the fixture enclosure. The fixture is available with a yoke mount or 3/4 inch NPT pendant mount and is supplied without a cord.

Where This Product Fits Best

This fixture fits hazardous and marine installations requiring Class I, Division 2 equipment, wet-location suitability, and high-output illumination. Its broad beam pattern is suited to layouts that need wide light distribution.

  • hazardous location lighting
  • explosion proof lighting
  • chemical processing facility lighting
  • paint booth lighting
  • oil and gas facility lighting
  • marine environment lighting

UL 844 hazardous location listing, Class I Division 2 Groups A, B, C, and D classification, IP66 protection, NEMA4X construction, and UL 1598A Marine Outside Type support these applications.

Installation and Long-Term Use

Installers can use the yoke mount where fixture aiming is required or the 3/4 inch NPT pendant mount for suspended installation. The 33.29-pound fixture weight must be considered when confirming mounting support.

Set wattage and color temperature before final commissioning. Verify supply voltage, dimming wiring, mounting method, and fixture layout before installation.

How This Fixture Is Commonly Used

In hazardous location lighting, explosion proof lighting, paint booth lighting, and chemical processing facility lighting, the fixture is positioned to distribute light across the intended work area from the selected mounting height. The 120 degree optic supports broad fixture coverage rather than narrow directional lighting.

Marine environment lighting and oil and gas facility lighting layouts should account for fixture mounting height, mounting orientation, and required light distribution. Higher wattage can reduce fixture count, but spacing and mounting height still determine uniformity and glare control.
