Entrances and lobbies are the first introduction to a commercial interior. Effective lighting should support safety and navigation.

Many facilities assume their lighting is performing well as long as the lights turn on and employees can see their surroundings. While basic visibility is important, effective commercial lighting is about much more than simply illuminating a space. The design of a lighting system can affect productivity, safety, employee comfort, energy consumption, and the overall functionality of a facility. In some cases, organizations may continue to replace lamps or add fixtures without realizing that the underlying issue lies in the lighting design itself. Recognizing the signs of a lighting design problem can help facility managers identify opportunities for improvement and create environments that better support day-to-day operations. Employees Frequently Complain About Visibility One of the most obvious warning signs of a lighting design issue is recurring employee feedback about visibility. Workers may mention difficulty reading labels, seeing fine details, or performing tasks accurately. Others may find themselves moving to different locations or adjusting their work positions to compensate for inadequate lighting conditions. When these complaints become common, the problem is not always that the facility lacks sufficient lighting. In many cases, the issue stems from how light is distributed throughout the space. Bright areas combined with dim work zones can create inconsistent visibility, making tasks more difficult than they should be. A successful lighting design ensures that the right amount of light is delivered where work is actually being performed. Glare Is Creating Discomfort Many people associate lighting problems with spaces that are too dark. However, excessive brightness can be just as disruptive. Glare occurs when light reflects off surfaces or shines directly into a person's field of vision. It can lead to eye strain, headaches, fatigue, and reduced comfort throughout the workday. Common signs of glare include: Employees squinting while performing tasks Reflections on computer monitors Bright hotspots in work areas Frequent adjustments to workstation positions Complaints about eye fatigue Simply adding more fixtures is rarely the solution. Effective lighting design involves balancing illumination levels while minimizing unwanted glare that interferes with occupant comfort.
