Obviously, bright lights are needed in the lab in order to see well. However, switching to light-emitting diodes (LED) instead of conventional lighting can substantially reduce energy usage. Other ways to cut back on lighting include installing sensors in rooms that are not used as often, such as cold rooms, labs that are used only occasionally for special testing, offices, and lounge areas.
Another thing to remember: When planning new labs or additions to existing labs, consider the location. Although laboratories are often relegated to basements and dingy corners, labs can, in fact, be built above ground and with windows. Laboratories that incorporate floor-to-ceiling windows have been built - this is not only helpful in reducing lighting needs but has a very positive effect on the laboratorians at work. Studies have shown that natural light has a powerful and positive impact on mental and physical health, levels of stress, and feelings of well-being.2
The images below are examples of LED lights and traditional fluorescent lights.
