20 / 24 / 32 / 40 Wattage Adjustable Architectural Linear Light | 2200 to 4600 Lumens | 2700K / 3000K / 3500K / 4000K / 5000K Adjustable | 100-277V | 4 Foot

Product Overview

This is a 4-foot architectural linear LED fixture with selectable wattage and color temperature. It is designed for commercial ceiling and architectural lighting where visual uniformity and clean lines are required. The fixture replaces traditional fluorescent strips and is suitable for continuous row or stand-alone installation in offices, retail, corridors, and similar environments.

Selectable output and color temperature allow adaptation to a range of interior lighting needs. Typical mounting heights are 8 to 12 feet, with chain-cable or surface mounting options for drop ceilings, drywall, or exposed structure.

Core Performance and Output

This fixture offers four selectable wattage settings: 20W, 24W, 32W, and 40W, delivering 2200 to 4600 lumens. Efficacy is 115 lumens per watt. The polycarbonate lens provides a wide 360° beam distribution, supporting even illumination for open areas or continuous runs.

Color temperature is field adjustable from 2700K to 5000K in five steps. 0-10V dimming is standard. Output is well-suited for general ambient lighting in commercial interiors. At lower mounting heights, the highest output setting may produce excessive brightness or glare if not spaced appropriately.

Adjustability and Control Options

Wattage and color temperature are both adjustable via onboard switches, allowing field selection during installation or future reconfiguration. This supports changes in layout or lighting requirements without fixture replacement.

0-10V dimming is integrated for use with compatible controls. No onboard occupancy or daylight sensors are included. The fixture supports both continuous row and individual mounting for flexible layout design.

Longevity and Reliability

The fixture is rated for 100,000 hours (L70) at typical operating conditions. The LED driver and light engine are designed for long-term use in commercial environments with frequent switching or dimming cycles.

Operating temperature range is -4°F to 122°F. No special maintenance is required beyond standard cleaning and periodic inspection of mounting hardware. The fixture is covered by a 5-year warranty.

Build Quality and Physical Characteristics

The housing is finished in white and measures 47.5 inches long, 2.1 inches wide, and 3.2 inches high. Weight is 8 lbs. The polycarbonate lens provides impact resistance and uniform light diffusion.

Chain-cable and surface mounting options are supported. The fixture is suitable for standard 100-277V operation at 50/60 Hz. All components are UL listed. No wet location or vandal-resistant ratings are included.

Where This Product Fits Best

This fixture is intended for indoor commercial and architectural environments where linear, uniform lighting is required. It is commonly used in spaces that demand clean aesthetics and flexible output for changing needs.

• architectural linear lighting
• commercial interior linear lighting
• office linear lighting
• retail linear lighting
• corridor linear lighting
• hospitality linear lighting
• continuous row lighting
• accent linear lighting

Environments are typically conditioned spaces with standard ceiling heights. The fixture is not intended for wet locations, high-abuse areas, or exterior use.

Installation and Long-Term Use

Chain-cable and surface mounting hardware are compatible with most commercial ceiling types. The fixture can be installed as a single unit or in continuous rows for longer runs. Power connection is made via standard wiring methods; no special tools are required.

Field adjustability of wattage and color temperature supports future changes in space use or lighting standards. Routine cleaning of the lens and inspection of mounting hardware are recommended for long-term performance.

How This Fixture Is Commonly Used

Typical mounting heights range from 8 to 12 feet, with fixtures spaced to achieve uniform illumination based on output setting and room geometry. Continuous row installation is common in corridors, open offices, and retail aisles.

Spacing and fixture count depend on selected wattage and desired light levels. Higher output settings reduce fixture count but may increase glare in low-ceiling spaces. Dimming controls are often used to fine-tune light levels for occupant comfort.

Safety, Certifications, and Warranty

This fixture is UL listed and meets requirements for commercial interior lighting. It is eligible for utility rebates where applicable. The product is covered by a 5-year warranty from the date of installation.

No additional safety features such as emergency battery backup or tamper resistance are included. The fixture is intended for dry, indoor use only.
