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 27-watt explosion proof jelly jar LED light provides 3,780 lumens at 5000K for hazardous location lighting. Its compact 9 x 13 inch housing supports surface, wall, and 3/4 inch NPT pendant mounting.
The fixture is configured for Class I, Division 2 and Class II, Division 1 hazardous locations. It is also used for paint booth lighting where a durable enclosed fixture and defined hazardous-location ratings are required.
Core Performance and Output
The fixture produces 3,780 lumens at 140 lumens per watt. A 120 degree beam distribution provides broad general illumination from a single jelly jar fixture.
Input voltage is 100-277V at 50-60Hz. Power factor exceeds 0.95 and total harmonic distortion is below 10 percent. The 3,780-lumen output can be excessive where fixtures are mounted close to work surfaces, while higher mounting positions may require a denser layout to maintain light levels.
Adjustability and Control Options
This fixture supports 1-10V dimming. Dimming control allows output adjustment where the connected control system is designed for 1-10V operation.
The fixture is available for surface, wall, or 3/4 inch NPT pendant mounting. Mounting selection should match the available structure, fixture orientation, and required light distribution.
Longevity and Reliability
Rated life is 50,000 L70 hours. The LED system is designed to maintain 70 percent of initial output at the stated life rating.
The fixture includes a 5-year warranty. Its enclosed construction is suited to locations where fixture access and routine replacement can be difficult.
Build Quality and Physical Characteristics
The housing is copper-free aluminum and the fixture weighs 14 pounds. Overall dimensions are 9 x 13 inches.
The fixture is rated IP66 and IK10. The compact jelly jar form supports installations where a larger hazardous-location fixture is not practical.
Where This Product Fits Best
This fixture fits hazardous and industrial environments requiring a Class I, Division 2 or Class II hazardous-location fixture. Its mounting options support fixed installation on walls, surfaces, and pendant stems.
- hazardous location lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- marine environment lighting
- wastewater treatment lighting
IP66, IK10, UL 1598 wet-location suitability, UL 1598A Marine Outside Type, and ABS ratings support use in demanding operating environments. Final application fit must match the facility hazardous-area classification.
Installation and Long-Term Use
Install the fixture using the selected surface, wall, or 3/4 inch NPT pendant mounting method. The 14-pound fixture weight and mounting structure should be considered before installation.
Use the 100-277V supply range and 1-10V dimming connections where applicable. Long-term service planning should account for fixture access, mounting orientation, and the hazardous-location classification of the installation area.
How This Fixture Is Commonly Used
In hazardous location lighting and paint booth lighting, the fixture is mounted where its 120 degree distribution can provide broad local illumination. Surface and wall mounting are used where the fixture must remain close to a structural plane, while pendant mounting places the fixture below the mounting structure.
Layout patterns depend on mounting height, target light levels, and obstructions within chemical processing facility lighting, oil and gas facility lighting, and wastewater treatment lighting. Higher output can reduce fixture count, but wider spacing can reduce uniformity between fixtures.
