Light is the biggest external factor that controls our body clock. It influences our mood and energy throughout the day. Human bodies are programmed to run in sync with natural light of the sun.

Our lamps mimic the color and brightness of the sun. They are an easy and effective way to getting exposure to bright light indoors.

This can usually be solved simply by switching off the light and, over the next few days, gradually building up the time you spend in front of it to find a usage time that works best for you.
