Horticutral Lighting
In today’s fast-paced world, lighting plays a critical role in our daily lives. According to research, specific wavelengths and intensities of light can improve our moods, biological processes, and overall health. Tunable white LED lighting has emerged as a dynamic and flexible lighting to support human centric lighting (HCL) as a result of advancements in LED technology. Tunable white lighting allows for the adjustment of its color temperature, benefiting our health, productivity, and comfort. Tunable white lighting can also help to minimize energy consumption and maximize lighting performance. It is an exciting option for residential, workplace, and industrial applications.
What is tunable white lighting
So what is tunable white lighting?
Tunable white lighting means the ability to control a light source’s color temperature output. It is also called variable white, dim-to-white, or custom temperature lighting from different manufacturers. Tunable white lighting enables people to adjust the color of light from warm to neutral to cool in appearance, based on applications, event needs, and occupant preference. Tunable white lighting has various applications in healthcare facilities, educational institutions, homes, commercial environments, and industrial spaces. It is the basement of Human Centric Lighting.
White tunable VS dim to warm
There are three basic categories of color-tunable lighting products:
- Dim-to-warm: These products change their color temperature from cool to warm as they are dimmed, similar to incandescent lamps.
- White-tunable: These products can change their color temperature across a range of white light, such as from 2700 K to 6500 K.
- Full-color-tunable: These products can change their color temperature across the entire visible spectrum, including colors other than white
Most people are confused about tunable white and dim to warm. Let’s check out their differences.
Dim to warm lighting mimics the dimming curve of incandescent lights when dimming. So it is also referred to as “incandescent-like” dimming. CCT of these products usually range from 3000K at full output down to as low as 1800K. Dim to warm lighting reduces the color temperature along with the brightness. Therefore, for dim to warm lighting products, only one control signal is needed per group of fixtures. The function of color temperature changing makes dim to warm lighting a popular option for places where need whiter light in the day and warmer light in the evening. But it might be an issue for some users who want to reduce light intensity without changing color temperature.
In contrast, tunable white light simulates natural daylight. ‘Tunable’ can be a color change over the day. By using two sets of phosphor-coated LED primaries, tunable white lighting products allow adjustment of CCT across a defined range from warm to cool. Most importantly, the brightness of tunable white lighting is not related to CCT.
How does tunable white lighting work
Tunable white lighting works by using LED light fixtures that contain two or more colors of LED chips. Typically, tunable white lighting fixtures have both cool white and warm white LED chips.
To better understand the difference in variable white lights, we use CCT (Correlated Color Temperature) to measure the color temperature of light. CCT is measured in degrees Kelvin (K). Within the LED industry, the measurement of CCT ranges from 1800K (candlelight) to 7000K (daylight). The higher the CCT, the cooler the white color. By adjusting the CCT of light sources to mimic natural daylight and circadian rhythms, tunable white lighting is able to provide a more dynamic lighting experience.
A tunable white lighting system has separated control inputs for intensity and color temperature. This ensures the color temperature remains constant when the intensity is adjusted. The control inputs for tunable white lighting fixtures can be 0-10V dimming, DMX, DALI, etc. The control system can be a simple switch or a more complex system that uses a smartphone app or automation system. With tunable white lighting, you can create a range of different atmospheres, from a warm, cozy glow for relaxing in the evening, to a bright, cool light for working during the day.
Why you need tunable white lighting
Tunable white lighting are beneficial. Some of the benefits of tunable white lighting are:
- It can control circadian rhythm through light manipulation. Circadian rhythm is your body’s clock that tells you when to wake up and when to sleep. Tunable white lighting can mimic natural light and support your circadian rhythm, which can improve your health and well-being.
- It can increase productivity and alertness. Studies have shown that light color temperature can impact a person's mood and productivity. Tunable white lighting can be used to create a specific ambiance to enhance mood and improve productivity in various settings such as offices, factories, and healthcare facilities.
- It can create different moods and atmospheres for different occasions or activities. Tunable white lighting can change the ambiance of a space according to your preferences or needs.
- It can save energy and reduce maintenance costs by using fewer fixtures and lamps. Tunable white lighting is more energy-efficient than traditional lighting systems. Since it's possible to adjust the color temperature and brightness, it's possible to save energy by lowering the light output when it's too bright or too dim, reducing running costs.
- It can make more flexible and customized lighting. Unlike traditional lighting systems, tunable white lighting is incredibly flexible, allowing you to create different lighting schemes to suit different moods or activities. It is fully customizable, enabling you to tailor the lighting to your preferences.
Upgrade your lighting experience with tunable white lighting and transform your space with adjustable brightness and color temperature.
