Technical Specifications & Parameters

Key Features & Professional Benefits

Selectable Power & Color Technology

The Slot 4 Series eliminates the need for multiple SKUs. The built-in switches allow installers to choose between three wattage settings (20W/30W/40W) and three color temperatures (3000K/4000K/5000K) on-site. This ensures the lighting meets the exact needs of the end-user even if design requirements change during construction.

Precision Engineering for T-Bar Grids

Measuring exactly 47.76 inches, this fixture is optimized for standard North American T-Grid systems. Its shallow 2.52-inch depth makes it an ideal solution for plenum spaces with limited clearance or heavy HVAC ducting.

Seamless Continuous Runs

Engineered for modularity, the Slot 4 Series can be installed as individual 4ft units or joined together to create infinite, light-leak-free linear runs. Our advanced joining system ensures a unified visual appearance without dark spots at the connections.

Advanced Optical System

The high-transmission frosted lens is designed to provide uniform, glare-free distribution. It hides the LED pixels completely, creating a smooth “ribbon of light” that enhances visual comfort and reduces eye fatigue in high-task areas like classrooms and open offices.

Mounting & Family Variations

• Recessed Flanged: Ideal for drywall ceilings where a clean 1/2″ trim hides the rough-in cut.

• Recessed Flangeless (Trimless): A “mud-in” solution for an invisible transition between the ceiling and the light slot.

• Pendant & Surface Mount: Matching Slot 4 fixtures are available in suspended or ceiling-mounted versions to maintain a consistent design language throughout the building.

Buying Guide: Choosing the Right Configuration

• For Corridors: 20W setting provides efficient, soft ambient lighting.

• For General Offices: 30W setting typically meets standard footcandle requirements for productivity.

• For Retail & Lobbies: 40W setting delivers high-impact illumination to highlight products and architectural features.

What is a 4-Inch Wide Slot Recessed Light?

In architectural terms, a “Slot” refers to a linear recessed opening. A 4-inch wide aperture is the industry standard for creating bold, structured lines of light. Unlike standard 2×2 or 2×4 troffers, Slot 4 lighting focuses on the geometry of the space, allowing the light to become part of the building’s skeletal design.

Why 4-Foot LED Linear Fixtures are the Industry Standard

The 4ft length is preferred by electrical contractors because it balances ease of handling with rapid coverage of large areas. It is the most searched length in the “Recessed Linear” category due to its compatibility with standard shipping pallets and ceiling grid modules.

Top Brands and Market Comparison

While major brands like Acuity Brands (Mark Architectural Slot 4) and Focal Point (Seem 4) lead the market, our Slot 4 Series provides a competitive alternative that focuses on “All-in-One” flexibility. By integrating selectable wattage and CCT into a single 4ft architectural housing, we provide distributors with a versatile tool that meets the specifications of multiple top-tier product lines.
