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 wattage, adjustable color temperature, and combined up/down illumination for commercial interior linear lighting. It operates on 100-277V and can replace fluorescent strip fixtures in compatible lighting upgrade projects.
Core Performance and Output
Selectable wattage settings of 20W, 30W, 40W, 50W, and 60W correspond to lumen outputs from 2600 to 7800 lumens. The fixture delivers 130 lumens per watt with a 120-degree beam distribution and an 80+ CRI.
Adjustability and Control Options
The fixture has selectable 3000K, 3500K, 4000K, 5000K, and 6500K color temperature settings. Wattage is also adjustable, allowing output selection from 2600 to 7800 lumens.
0-10V dimming is supported for installations using compatible dimming controls. Up/down lighting distributes light above and below the fixture for architectural linear installations.
Longevity and Reliability
The architectural linear fixture is rated for 50,000 hours at L70 and has a 5-year warranty. Its operating temperature range is -4 degrees F to 104 degrees F.
Build Quality and Physical Characteristics
The black fixture uses a die-cast aluminum housing and polycarbonate lens. It measures 46.5 inches long by 2.2 inches wide by 2.95 inches high and weighs 7 pounds.
Where This Product Fits Best
This linear fixture is suited to interior projects that use suspended or surface-mounted linear lighting and benefit from selectable output, selectable color temperature, and up/down distribution.
