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 4-foot explosion proof linear LED light delivers 5,600 lumens at 40 watts with a 5000K color temperature. It is built for classified hazardous-location installations requiring a linear fixture with wide 120-degree distribution.
The fixture is listed as a replacement for 175-watt or 250-watt metal halide lighting. Its 3/4-inch NPT pendant and yoke mounting options support common hazardous-location mounting arrangements.
Core Performance and Output
The fixture produces 5,600 lumens at 140 lumens per watt. A 120-degree beam angle and polycarbonate lens provide broad distribution from the linear housing.
Available voltage configurations are 100-277V and 277-480V at 50-60Hz. Power factor is greater than 0.95 and THD is less than 10%.
At lower mounting heights, 5,600 lumens can create excessive brightness if fixture placement is too dense. Higher mounting positions require layout review to maintain uniform coverage.
Adjustability and Control Options
This fixture supports 1-10V dimming. Dimming control selection must match the installed voltage configuration and control system requirements.
The standard 120-degree beam distribution is fixed. The fixture does not list alternate beam-angle options.
Longevity and Reliability
Rated life is 50,000 hours at L70. The listed operating temperature range is -22F to 122F.
The fixture is covered by a 5-year warranty. Its IP66 rating supports wet-location exposure, and its IK08 rating addresses impact resistance.
Build Quality and Physical Characteristics
The housing is copper-free aluminum with a gray finish. The lens is polycarbonate.
Fixture dimensions are 47 x 4.7 x 9.5 inches. Fixture weight is 15 pounds.
Yoke mounting provides a surface-mounted installation arrangement. The 3/4-inch NPT pendant option supports pendant-mounted installations where the mounting system is designed for the fixture weight.
Where This Product Fits Best
This fixture fits classified hazardous locations where a 40-watt linear fixture, broad light distribution, wet-location suitability, and the listed Class I, II, and III classifications align with the installation requirements.
- hazardous location lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- refinery lighting
- marine environment lighting
- wastewater treatment lighting
It carries IP66, UL 1598 wet-location, UL 1598A Marine Outside Type, ABS, and NSF ratings. Final application fit depends on the required class, division, group, voltage, mounting method, and fixture layout.
Installation and Long-Term Use
Confirm the hazardous-location classification before installation. This fixture is listed for Class I, Division 2, Groups A, B, C, and D; Class II, Division 1, Groups E, F, and G; Class II, Division 2, Groups F and G; and Class III.
Select either the yoke mount or 3/4-inch NPT pendant mount based on the installed support structure. Verify that the structure and mounting components support the 15-pound fixture.
Use the voltage configuration specified for the electrical system. Access to the fixture and its dimming wiring should be considered before final mounting location is established.
How This Fixture Is Commonly Used
In hazardous location lighting, paint booth lighting, and chemical processing facility lighting, the linear form factor is placed to provide broad coverage across the required work area. Mounting height is determined by the existing structure, classification requirements, and target light level.
For oil and gas facility lighting, refinery lighting, marine environment lighting, and wastewater treatment lighting, fixtures are arranged around the installed equipment and access paths within the approved area. The 120-degree distribution supports broad layout patterns rather than narrow directional coverage.
Spacing varies with mounting height, target light levels, and the 5,600-lumen output. Closer fixture spacing can increase brightness and overlap, while wider spacing can reduce uniformity.
