In warehouses, logistics centers, gyms, and workshops, lighting is not only about brightness. If the light feels harsh or uncomfortable, glare may be the reason.

While lumen output and energy efficiency are important, Unified Glare Rating (UGR) plays a key role in visual comfort, workplace safety, and overall lighting quality.

What Is UGR?

UGR stands for Unified Glare Rating. It is used to evaluate discomfort glare in indoor lighting installations.

A lower UGR value means better visual comfort. A higher UGR value means stronger glare and a greater chance of eye strain or visual fatigue.

In industrial lighting, glare often becomes more noticeable when workers look upward or view luminaires from an angle, especially in high-bay applications.

Comfortable Design

Reduced Eye Fatigue

Workers exposed to high-glare lighting for long periods may experience eye strain, headaches, and reduced concentration.

Low-glare lighting helps create a more comfortable working environment, allowing employees to stay focused during long shifts.

Improved Safety

In warehouses and manufacturing facilities, workers often look upward to locate inventory, check equipment, or operate forklifts and overhead cranes.

Excessive glare can reduce visibility and increase the risk of mistakes or accidents. Controlled glare helps improve visual clarity and workplace safety.

Compliance with Lighting Standards

Workplace lighting standards, such as EN 12464-1, include recommended UGR limits for different indoor applications.

For many work areas, UGR 19 or UGR 22 is commonly used as a reference target, depending on the visual task and working environment.

Visual comfortable

Good lighting improves more than visibility. It affects comfort, concentration, and the overall experience of people working in the space.

A lighting system with controlled glare, good uniformity, and balanced brightness creates a more pleasant and productive workplace.

 Goldenlux Improvement

Goldenlux UFO High Bay and Linear High Bay luminaires are designed with optical systems that help reduce glare and improve visual comfort.
