Black LED Linear Wall Light1. LINEAR PENDANT SERIES Clean Lines. Continuous Light. Commercial-Grade Precision. Engineered for modern workplaces that demand both form and function, the Linear Pendant Series delivers uninterrupted luminous lines with architectural rigor. Featuring seamless connector technology, these fixtures can be joined into continuous runs up to 12 feet (3.6m)—or extended further with centralized power feeds for large-scale installations—eliminating visible gaps and ensuring visual rhythm across open offices, conference suites, retail counters, or educational labs. Available in standard lengths (2', 3', 4', 6', 8') and field-cuttable options, the series supports rapid deployment across multi-site rollouts. Choose from matte white, brushed aluminum, matte black, or custom powder-coated finishes—all applied in our ISO-certified factory for color consistency and durability. With CRI >90, flicker-free drivers, and 0–10V/DALI dimming, these pendants meet WELL Building and LEED lighting requirements while reducing energy use by up to 60% vs. legacy fluorescent systems.

Key Technical Features & Customization

This linear light is built for flexibility, allowing you to tailor the atmosphere on-site through advanced smart color tuning and power options.

  • Selectable Wattage & CCT: Eliminate the guesswork in procurement. Each direct and indirect lighting fixture features selectable wattage and selectable CCT, allowing you to adjust both the power output and the color temperature (3500K/4000K/5000K) after installation to match the interior’s needs.

  • Direct and Indirect Balance: Featuring an independent upward pendant component for indirect ceiling wash and a powerful down-light for task areas. This dual lighting distribution helps in illuminating walls and work surfaces evenly, creating a voluminous, airy feel in any space.

  • Visual Comfort: Our lighting fixtures prioritize high-quality optics for glare-free dimming. With a low UGR (Unified Glare Rating), it ensures a soft but bright environment that reduces eye strain in high-productivity professional settings.

Advanced Application Scenarios

1. Modern Office & Coworking Spaces

A bidirectional suspension is essential for contemporary workspaces. By reflecting light off the ceiling (indirect), it reduces screen glare on monitors, while the direct light provides the 40-60 foot-candles required for detailed paperwork.

2. High-End Retail & Showrooms

Use the 8ft linear pendant to create long, continuous “rivers of light.” The high CRI 90+ option ensures that merchandise colors appear vibrant and true to life under modern pendant lighting.

3. Educational & Healthcare Facilities

With glare-free dimming and color temperature tuning (up to 5000K for focus), these suspension lights support the circadian rhythms of students and patients, promoting wellness and concentration.

Installation & Modular Design

Whether your project requires hanging lights, ceiling pendants, or suspension lights, the Prillum series adapts to your structural vision.

  • Sleek Suspension: These minimalist halo fixtures act as a clean alternative to traditional chandeliers, offering a modern finish that complements current design trends.

  • Modular Linking System: Our innovative “Quick-Connect” system allows these lighting fixtures to be linked end-to-end. Create seamless, unbroken runs of light up to 40 feet on a single power drop.

  • Multiple Mounting Options: Supports Aviation Cable Suspension, Surface Mounting, or Wall Mounting to suit various ceiling types.

Why Specifiers Choose Prillum?

  • Architectural Design First: A slim, 2.76″ wide profile that integrates into the ceiling landscape without visual clutter.

  • Energy Efficiency: DLC Premium listed efficacy (up to 130 lm/W) ensures your project qualifies for maximum utility rebates.

  • Reliability: 5-Year Warranty with a 50,000-hour rated L70 lifespan.

Final Summary for Specifiers

The Prillum up and down pendant light series is more than just a light source; it is a tool for architectural design. By combining glare-free dimming, selectable CCT, and a stylish pendant lights aesthetic, it simplifies the lighting specification process while delivering professional-grade results.

What is Direct/Indirect Lighting?

Bidirectional lighting is a system where light is emitted in two opposite directions. In a two-way LED light bar, the “down” component provides focused task lighting, while the “up” component bounces light off the ceiling to create a soft, ambient glow. This dual lighting distribution eliminates the harsh shadows often found in one-directional lighting.

Key Benefits of Two-Way Pendants

The primary advantage is the reduction of eye strain and the elimination of the “cavern effect” where ceilings remain dark. By illuminating walls and ceilings simultaneously, these hanging lights make a room feel larger and more inviting. They are the gold standard for commercial use and high-end indoor lighting.

Explore by Design Type

  • Linear Suspensions: The most popular choice for modern offices and dining areas. These slim ceiling pendants offer a continuous run of light, perfect for projects that emphasize clean lines.

  • Drum and Cylinder Pendants: For a more localized dual emission, these provide a classic silhouette. Often used in foyers, offering a concentrated task light with a subtle crown of light above the fixture.

  • Multi-Light Systems: Combining multiple units on a single canopy creates a dramatic architectural chandeliers effect, ideal for high-ceiling lobbies.

How to Choose the Right Bidirectional Fixture

Sizing and Scale Considerations

A common mistake is selecting a fixture that is too small. For a dining table, choose a hanging light that is approximately 1/2 to 2/3 the width of the table. For commercial use in large offices, modular systems can be linked to match the length of the room.

Selecting Quality Components

When choosing lighting fixtures, look for brands that offer selectable CCT and high CRI (90+). Quality products ensure that the glare-free dimming is smooth and that the color temperature remains consistent across multiple linked units.

Installation and Placement Tips

For optimal balanced illumination, hang your fixture approximately 30–36 inches above a surface. To maximize the effect of the indirect light, ensure there is at least 12–18 inches of space between the top of the fixture and the ceiling.

Final Summary for Specifiers

The Prillum direct and indirect lighting series is more than just a light source; it is a tool for architectural design. By combining glare-free dimming, selectable CCT, and a stylish aesthetic, it simplifies the lighting specification process while delivering professional-grade results.
