Benefits of Tunable White Light

Benefits of Tunable White Light

In the world of LED, there is no such thing as a single shade of white. Even if you’re lighting your home without an obvious palette, you’ll need to consider the warmth and brightness you choose.
White lighting you can tune has performed well in several studies, controlling biological clocks and enhancing health. Cool whites make you alert, while warm ones encourage restfulness and serenity.
Fluorescent lighting has been well studied in the past, but LEDs have outperformed them, partly because they achieve a more diverse gradient.


Lighting intensity affects alertness drastically, so it has important applications in institutions. Teachers can control light to support variations in learning styles, and nurses can control dimness to improve patient comfort. Dynamic lighting systems also offer circadian support, using red whites after noon and blue hues in the morning to suppress.


A Manchester CIE study found that women respond to warm whites and men to slightly cooler light. Tunable light can adapt itself to these preferences. Those who are ill or struggling with sleep disorders can benefit from red whites. Family members who spend most of their day under artificial light can minimize strain and discomfort through ergonomically dimmed lighting. The precise tunable white lighting system you choose has an impact, too. Not all LED luminaires offer enough range, and they all perform differently. Some are only tunable from dim to warm, while others are full-color tunable. Multi-chip technology seems to perform better than other forms of dynamic lighting.
White output hasn’t yet reached its zenith. Specific color ranges are difficult to achieve with traditional products, so three discrete lighting channels can offer a more tailored experience to those who need it.
