調整可能な白色 LED 線形ライト: オフィスの雰囲気と生産性を向上

Introduction: The Role of Lighting in Office Productivity

The shift to hybrid work after the pandemic has prompted many companies to rethink how office spaces are designed. To encourage employees to return, businesses are prioritizing healthier, more comfortable environments—focusing on air quality, acoustics, and lighting.

Lighting, in particular, has a direct effect on employees’ comfort, concentration, and well-being. A study by the American Society of Interior Designers, in collaboration with Cornell University and Delos, revealed that 68% of office workers were dissatisfied with their lighting. This dissatisfaction is often related to glare-induced eye strain, fixed color temperatures that don’t match task requirements, or overly harsh lighting in spaces meant for relaxation.

Tunable white LED linear lights offer a practical solution.
By enabling dynamic adjustment of color temperature—from warm 2700K to cool 6500K—these fixtures support the body’s natural circadian rhythm, reduce discomfort caused by poor lighting, and create environments better suited to the varied activities within a modern office.

What Are Tunable White LED Linear Lights?

Tunable white LED linear lights are long linear LED light fixtures that allow users to adjust the color temperature of the lighting throughout the day—typically from warm 2700K to cool 6500K.

Warm tones (around 2700K–3000K) create a calm and welcoming atmosphere, ideal for lounges or casual meeting areas. Cooler tones (5000K–6500K) promote alertness and focus, making them suitable for task lighting in workstations, meeting rooms, or collaborative spaces.

In terms of form, these fixtures are defined by their slim, elongated linear shape. Common lengths include 1.2 meters and 2.4 meters, with the flexibility to use as standalone units or link multiple fixtures in sequence or matrix layouts.

The wide beam angle—typically between 120° and 160°—allows for uniform, shadow-free illumination over large areas. This makes them especially suitable for open-plan offices, corridors, or creative studios where both functional lighting and visual aesthetics are required.

These lights often use a dual-chip setup, combining warm white and cool white LEDs on a single board. Control options include DALI, 0–10V dimming, DMX, and app-based smart systems for real-time or scheduled adjustments.

Application Scenarios: Enhancing Different Office Zones

Tunable white LED linear lights are ideal for modern office environments that require flexibility, comfort, and energy efficiency. By adjusting color temperature and brightness based on the activity and time of day, these fixtures support both visual performance and occupant well-being.

Open-Plan Workspaces

Cooler tones (5000K–6500K) are recommended to improve focus and productivity. For optimal visual comfort, it’s advisable to pair the luminaires with low-glare diffusers (UGR ≤19) to minimize screen reflections.

Installation height should typically range from 2.5 to 3 meters above desk level to ensure even light distribution across workstations.

Meeting Rooms

Tunable lighting can support pre-programmed scenes tailored to different meeting types:

• Video Conference Mode: 4000K, 400 lux, with focus lighting on participants’ faces to enhance clarity on camera.
• Brainstorm Mode: 3500K, 300 lux, with brightness slightly dimmed (−10%) on the room’s perimeter to create a relaxed, focused atmosphere.

Dimming and color changes can be controlled via wall panels, DALI systems, or app-based platforms, allowing seamless transitions between modes.

Reception Areas

The reception area sets the tone for visitors and staff alike. A neutral to slightly warm white tone (3000K–4000K) helps create a welcoming atmosphere without appearing overly casual.

Linear fixtures can be suspended to add architectural rhythm to the space. In some designs, they are arranged in parallel or geometric patterns to enhance visual interest.

Breakout Zones & Lounges

In breakout areas where employees take short breaks, softer warm tones (2700K–3000K) are preferred to promote relaxation and mental recovery.

Lower illumination levels (150–250 lux) paired with indirect lighting or diffused fixtures can help reduce stimulation and visual tension.

Multipurpose Rooms & Training Areas

These spaces require flexibility. Tunable white LED linear lights allow lighting to adapt to different activities—training, presentations, or informal discussions.

Typical setups may include:

• Presentation Mode：5000K，500 lux
• Training Mode：4000K，350–400 lux
• Discussion Mode：3500K，300 lux

Smart control systems can enable quick scene switching to match different functions of the room.

Benefits of Tunable White LED Linear Lights in Offices

Tunable white LED linear lights offer more than just visual comfort—they create adaptive, human-centered workspaces that foster well-being, productivity, and long-term efficiency. Key advantages include:

Supports Employee Well-Being and Productivity

By adjusting color temperature in alignment with natural circadian rhythms, tunable white lighting helps employees stay alert during the day and reduces fatigue, eye strain, and sleep disruption.

A 2013 study by the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute found that office workers exposed to human-centric tunable lighting reported better sleep quality and lower levels of stress and depression compared to those under conventional lighting.

In another real-world application, CBRE Netherlands partnered with two universities to install time-controlled tunable lighting in their Amsterdam office. Over a 7-month period, 120 employees experienced:

• 18% increase in productivity
• 12% improvement in work accuracy
• 76% boost in reported happiness
• 71% of employees felt more energized
• 50% reported feeling healthier

When the study concluded and the office reverted to its original lighting, one of the most frequent requests from staff was to restore the tunable lighting system—highlighting its positive psychological and physiological effects. These findings reinforce the value of tunable white lighting in promoting healthier, more engaged, and more productive office environments.

Flexible and Aesthetic Design Options

Slim linear fixtures are highly versatile for modern architectural integration.

Suspended designs—commonly known as tunable white LED pendant lights or suspended linear lights for offices—help create visual interest in open-plan spaces

Recessed or surface-mounted options suit minimalist, space-efficient interiors

Lighting designers can create tailored environments that enhance both function and aesthetics.

Enhanced Control and Energy Efficiency

Tunable white LED linear lights are inherently energy-efficient, typically consuming 40%–60% less power compared to traditional fluorescent fixtures such as T5 or T8 tubes.

In open-plan offices or shared workspaces, one tunable fixture can serve dual functions—providing both task lighting and ambient lighting, thereby reducing the number of fixtures needed.

When integrated with smart lighting controls—such as occupancy sensors, daylight harvesting, or time-based dimming—energy usage can be reduced even further.

For example, in meeting rooms or corridors, lighting can automatically dim to 20% standby brightness when unoccupied, saving an additional 30% or more during off-peak hours.

This combination of base LED efficiency and smart control not only lowers energy bills but also extends fixture lifespan, reduces maintenance frequency, and supports LEED or WELL building certifications.
