What is Tunable White LED lighting?

Tuneable white lighting technology means that you can control the light sources’ colour temperature output mix cool and warm white light as per your choice. Tuneable white is mixing white light and warm white light, tuneable white, color temperature control, circadian lighting, human centric lighting or DALI type 8 protocol. with a control unit, such as a control panel or a lighting control software, you will be able to choose the desired color temperature anywhere between the specified color temperature range if LED driver and modules support that.

CCT stands for Correlated Color Temperature, and it refers specifically to the color temperature of white light, measured in Kelvin (K). For example, 3000K is called “warm white” in lighting, giving out a very yellowish shade of white; from human centric lighting point of view, the yellowish color temperatures refer to sunset and dawn. The higher degrees Kelvin, the cooler the white color temperature is, turning from yellowish white through pure white to bluish white (the coolest) – the brightest time of the day.

Why Tuneable White? It looks awesome. Dynamic lighting creates very different moods for spaces and changes your room ambience throughout the day. You can take your room from moody, warm, and relaxing into bright, modern and creative in seconds. But more important, Tuneable White can bring health benefits: It increases productivity and supports circadian rhythm, our in-built body clock responds more about Human-Centric lighting and wellbeing with lighting

At MELCON, we are human-centric lighting experts.

The lighting in areas where we work, learn or relax needs to be fine-tuned to our needs. Human-centric lighting can be tuned to imitate natural daylight, which means the lighting works according to harmony with our body’s natural circadian rhythms. People who observe human-centric lighting benefit from improved mood, productivity and concentration and typically report reduced workplace health issues, such as eye strain, fatigue, and headaches.

We understand the impact of light has on our wellbeing and functionality, so it’s one of our principal considerations when designing smart lighting controls and luminaire components which work with Automation.

As human beings, we’ve evolved over many years with a single daylight source which is Sun light. In more recent years, we have adapted to spending almost 90% of our time indoors. This lifestyle change means that we typically spend less time in natural light, so this has a huge impact on our circadian rhythms. The circadian rhythm is our natural body behaviour – it is responsible for our daily sleep-wake up routine. This rhythm is heavily reliant on the amount of light reaching our eyes. Fixed lighting is unnatural , because traditional lighting isn’t designed to support our wellbeing. It lacks the ability to tune lighting levels which is need of human body.. Modern and human-centric lighting controls, however, offer dynamic lighting features including brightness control and colour temperature control (DALI Type 8). By incorporating these dynamic features in an office, school or hospital, work place, a human-centric lighting system more accurately emulates natural light, therefore supporting the circadian rhythms of everyone using the area.
