Light affects the human non-visual system, including the circadian regulation of emotions. Bright light enhances focused feelings. Blue light makes you feel calm and serene. Natural light can make you happier. Warm whites make you feel comfortable and relaxed. Light can even affect your appetite.

Studies have found that light affects how much we eat, how fast we eat, what food we eat, and even our taste perception. Using a tunable white LED strip is a lighting treat. From very warm white to very bright white, the color temperature adjusts to the light of the day.

Tunable white LED strips have been used for years in high-end restaurants, bars, salons, hotels, and clubs, providing a better experience than ever before.

Scientific studies have shown that alertness is higher in bright light, leading to higher levels of attention. Conversely, the brain tends to be relaxed and less alert under warm, slightly red light, which can reduce pressure in the headspace and is ideal for teamwork and creative projects. Teachers can determine the light color temperature based on learning materials to achieve optimal learning conditions.

Related research has found that high color temperature and high brightness lighting are recommended in the morning and after lunch for working people. By doing so, people at work are essentially “stimulated” to improve alertness and attention, thereby improving performance.

At lunchtime or the end of the day, lighting CCT and brightness levels are reduced. Lunchtime is a time to relax and rejuvenate the body; at the end of the day, the body is given a break so that melatonin will begin to be produced on time.

Workplaces can also take advantage of the conference room and classroom lighting. It is beneficial to use adjustable white LED strips to adjust the different color temperatures in the conference room (i.e., increase attention, presentations, and brainstorming sessions).

Studies have shown that the correct choice of color temperature is beneficial to human health. Variable color temperature lighting can affect sleep, mood, concentration, work, and learning performance. Recent advances in color temperature-adjustable LED technology have made it possible to use them not only for lighting purposes but also to help improve the health of the user.

In the bedroom example above, the homeowner requires a different white color (color temperature) at different times of the day. The human body is needed to respond to the natural environment, the lighting environment.

Having lived for thousands of years in the sun’s daily cycle, humans have developed corresponding biological rhythms called circadian rhythms. Circadian rhythms are responsible for producing various hormones and levels of alertness and body temperature.

The various levels of all these things are adjusted continuously throughout the day based on an internal clock of about 24 hours; this clock sets the frequency of the circadian rhythm. The circadian rhythm uses external information in the form of light to reset and verify when hormone production starts or stops.

Since the advent of electric lighting, humans are no longer limited to the sun as the only light source. Because of this, humans can now extend their workday longer or earlier than ever before.

However, this new form of light can also impact circadian rhythms. By receiving unexpected light at the wrong time, the body can produce hormones at the wrong time, and alertness and temperature levels can get out of balance. This misalignment can lead to various medical symptoms, including reduced sleep and depression.

We use adjustable color temperature led strip lighting to replicate the color temperature light produced by the sun in a day. This means that the light in the morning and night does not have to be so strong, and it becomes brighter at noon. In this way, we provide near-natural lighting and maintain our body’s circadian rhythm to improve health.
