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 LED stairwell strip light is a wattage- and color-adjustable linear fixture with a built-in motion sensor. It operates from 100-277V and provides a selectable output range from 3102 to 6204 lumens.
The fixture replaces fluorescent strip lighting where a surface-mounted or suspended linear layout is required. Its 22W through 44W settings allow output to be matched to the existing layout and required light level.
Core Performance and Output
Selectable wattage settings are 22W, 28W, 36W, and 44W, producing 3102, 3948, 5076, and 6204 lumens. Fixture efficacy is 141 lumens per watt.
A 120-degree beam distribution and frosted lens provide broad light distribution from the 4-foot fixture body. Color temperature is selectable between 3500K, 4000K, and 5000K, with an 80+ CRI.
The fixture operates on 100-277V, 50/60Hz power and has a power factor above 0.90. The higher output settings can be excessive where fixtures are installed close to the work area or in low ceiling layouts.
Adjustability and Control Options
Wattage and color temperature are field adjustable. These settings allow one fixture configuration to be set for different output and color requirements within the supported ranges.
1-10V dimming is included. The fixture also includes a built-in motion sensor for occupancy-based operation.
Longevity and Reliability
The LED system is rated for 50,000 hours at L70. This rating identifies the point at which light output is expected to reach 70 percent of initial output.
The fixture carries a 5-year warranty. Long-term maintenance should include checking the fixture mounting, wiring connections, lens condition, and sensor operation.
Build Quality and Physical Characteristics
The housing is galvanized steel with a white finish. The frosted lens reduces direct visibility of the LED source across the 120-degree distribution.
Fixture dimensions are 46 7/8 by 2 1/2 by 2 11/16 inches. Unit weight is 4.6 pounds.
Surface mounting and V-hook mounting are supported. No cord is included with the fixture.
Where This Product Fits Best
This strip light fits lower-profile work, repair, and service spaces that use linear fluorescent strip fixtures or require a 4-foot linear layout. Its selectable output supports installations where light levels differ between areas.
- workshop lighting
- maintenance shop lighting
- garage lighting
- service bay lighting
- tool room lighting
- equipment repair lighting
Surface mounting works where the fixture mounts directly to the ceiling structure. V-hooks support suspended linear rows where the mounting arrangement permits them.
Installation and Long-Term Use
Install the fixture using either the surface-mount method or V-hooks. Confirm the selected mounting method supports the fixture weight and maintains a straight, consistent fixture alignment.
Set wattage and color temperature before final commissioning. Verify 100-277V supply voltage, 1-10V control wiring where used, and motion sensor operation after energizing the fixture.
For long-term use, keep the frosted lens clean and inspect mounting points during routine maintenance. Replace damaged mounting components or wiring before returning the fixture to service.
How This Fixture Is Commonly Used
In workshop lighting, maintenance shop lighting, and garage lighting, fixtures are commonly arranged in straight rows to follow work areas and circulation paths. Surface mounting is used where the ceiling plane supports direct attachment.
In service bay lighting and equipment repair lighting, V-hook mounting can support suspended fixture rows. Mounting height and fixture placement should maintain light distribution across the intended work area.
Spacing and layout vary with the selected wattage, mounting height, target light level, and 120-degree beam distribution. Higher output settings can reduce the number of fixtures required while increasing brightness directly below each fixture.
Safety, Certifications, and Warranty
This fixture is UL listed. It is rebate eligible.
The fixture is rated for 100-277V operation and includes a 5-year warranty. Follow the selected mounting method and applicable electrical requirements during installation.
Frequently Asked Questions
Q: What wattage and lumen settings are available?
A: The fixture is adjustable between 22W, 28W, 36W, and 44W. Corresponding output is 3102, 3948, 5076, and 6204 lumens.
Q: Can the color temperature be changed?
A: Yes. Color temperature is adjustable between 3500K, 4000K, and 5000K.
Q: What mounting methods are supported?
A: The fixture supports surface mounting or V-hook mounting. No cord is included.
Q: What affects fixture layout planning?
A: Layout planning depends on the selected wattage, mounting height, target light level, and the fixture’s 120-degree beam distribution. The supplied product data does not establish a specific spacing value or fixture quantity.
Application Questions and Clarification
Q: Is this fixture appropriate for maintenance shop lighting?
A: Maintenance shop lighting is a listed primary application. The selectable 22W through 44W output settings allow the fixture output to be matched to the planned layout.
Q: Can this fixture be used for tool room lighting?
A: Tool room lighting is a listed secondary application. Final fixture placement depends on mounting height, target light level, and layout requirements.
Q: What should be confirmed before using V-hook mounting?
A: Confirm that the planned mounting arrangement supports V-hooks and the 4.6-pound fixture weight. The fixture dimensions are 46 7/8 by 2 1/2 by 2 11/16 inches.
