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 architectural linear light provides adjustable 40W, 50W, or 60W output with selectable 3500K, 4000K, or 5000K color temperature. It is configured for down light only and uses a polycarbonate lens with a 120 degree beam distribution.
The fixture replaces fluorescent strip lighting in architectural linear lighting, office linear lighting, and retail linear lighting layouts. Chain-cable and surface mounting support suspended or ceiling-mounted installations.
Core Performance and Output
Output is selectable at 4,800, 6,000, or 7,800 lumens. Efficacy is rated at 130 lumens per watt, with 80+ CRI and a 120 degree standard beam angle for broad downward distribution.
The fixture operates on 100-277V, 50/60 Hz power and supports 0-10V dimming. The higher output settings can be excessive in lower mounting conditions, while mounting height and layout affect uniformity across longer linear runs.
Adjustability and Control Options
Wattage adjustment allows the fixture to operate at 40W, 50W, or 60W. Color temperature adjustment provides 3500K, 4000K, and 5000K selection before installation or commissioning.
0-10V dimming is provided for systems using compatible dimming controls. The fixture is down light only and does not provide uplight distribution.
Longevity and Reliability
The rated lifespan is 50,000 hours at L70. This rating supports long-term operation where access for fixture replacement can affect maintenance planning.
The fixture is rated for operation from -22 degrees F to 140 degrees F. Its five-year warranty applies to the listed product configuration.
Build Quality and Physical Characteristics
The housing is die-cast aluminum with a black finish. The polycarbonate lens protects the optical assembly while maintaining broad downlight distribution.
Fixture dimensions are 47.2 inches long by 2.5 inches wide by 2.95 inches high. Unit weight is 7 pounds.
Where This Product Fits Best
This fixture fits interior linear lighting layouts that need selectable output, selectable color temperature, and continuous fixture alignment. It is suited to suspended or surface-mounted interior installations.
- office linear lighting
- retail linear lighting
- commercial interior linear lighting
- architectural linear lighting
- corridor linear lighting
- continuous row lighting
Chain-cable mounting supports suspended layouts, while surface mounting supports direct ceiling installation. Continuous-run connectors support linked rows of up to seven fixtures.
Installation and Long-Term Use
The fixture mounts by chain-cable or surface mounting. Select wattage and color temperature before final commissioning so the installed output and appearance match the intended layout.
Included connector kits allow up to seven fixtures to link in a continuous run. Long-term access should account for the selected mounting method, electrical connections, and dimming wiring where 0-10V control is used.
How This Fixture Is Commonly Used
In office linear lighting and retail linear lighting layouts, fixtures are commonly arranged in straight suspended rows or direct surface-mounted lines. Continuous row lighting installations can link up to seven fixtures with the included connector kit.
Mounting height remains a layout factor because it affects the spread of the 120 degree downlight distribution. Fixture spacing varies with the selected wattage, target light level, mounting height, and row arrangement.
Safety, Certifications, and Warranty
This fixture is ETL listed. It is rebate eligible.
The operating temperature range is -22 degrees F to 140 degrees F. The warranty is five years.
