Tunable White

"Tunable White" is a lighting technology that allows the color temperature and brightness of light sources to be controlled adjustably. The color temperature of light is measured in Kelvin (K) and has a significant impact on the appearance and mood of a room.
Normally, the scale ranges from warm, yellowish light (low Kelvin values) to cool, bluish light (high Kelvin values).
Warm white light (2000 to 3500 Kelvin) creates a cozy and inviting atmosphere and is often used in homes, restaurants and hotels.
Neutral white light (3500 to 4500 Kelvin) is usually good for offices, conference rooms and stores because it creates a balanced and productive environment. Cool white light (above 4500K) can be used in areas where increased alertness and concentration are required, such as hospitals or industry.
By adjusting color temperature, Tunable White light can help match lighting conditions to different activities. For example, it can help change the mood in a room, improve sleep quality or optimize visual perception.
Tunable White can also be used to match light to natural daily rhythms by adjusting color temperature throughout the day. This can regulate sleep-wake cycles and promote well-being, especially indoors without access to natural daylight.

Practically, this can be implemented by combining cool white and warm white LEDs in combination with a control unit. Nichia's 2-in-1 LED is the world's first LED to combine a color temperature range of 2700 - 6500 Kelvin under one phosphor layer. This brings more flexibility and design advantages. Lumitronix has developed the innovative LEDs on the flexible strip LumiFlex560 Pro, the LED module MiniDaisy installed.
