Steve Mesh on the Building Blocks of Tunable White, Part 2

09/16/2020 by Lighting Controls Association Leave a Comment

The previous post on Tunable-White Building Blocks talked about differences between using low-level analog control technology as opposed to networked lighting control (NLC) systems that employ digital communication between components. Analog technology such as 0-10V dimmers can in fact be used to control certain color-changing luminaires. Let’s be specific about which types. There are actually three main types of color-changing lighting systems – “dim-to-warm”, “tunable-white”, and “RGB.”

Steve Mesh on the Building Blocks of Tunable White, Part 1

09/14/2020 by Lighting Controls Association Leave a Comment

“Tunable-white and other forms of color-changing lighting have added an extra dimension of capability, flexibility, and complexity to the lighting industry,” writes Mesh. “It’s almost as though we’ve gone from a 2-dimensional world to a 3-dimensional world based on the added complexity of controlling the luminaire’s coloration (typically measured by Correlated Color Temperature ) separately from the luminaire’s lumen output. Don’t be scared! Even though this has exponentially increased the complexity of the equipment and technology, you still don’t need a PhD in lighting to understand this new landscape.”

C. Webster Marsh on Overcoming the Challenges of DMX-Controlled Tunable White Lighting

12/30/2019 by Lighting Controls Association Leave a Comment

DMX-controlled tunable dynamic white luminaires are luminaires that use DMX controls to change their correlated color temperature (CCT) on demand, which provides a dramatic design tool to the modern lighting designer. These luminaires are different from dynamic color changing luminaires because instead of using colored LEDs, they use a mix of white LEDs such as warm white, neutral white, and cool white. When these hues are mixed at different intensities, the overall delivered CCT of the luminaire changes. It is very important to have a robust controls system specifically designed and programmed for the control of tunable dynamic white luminaires. Any compatible controller will control a DMX tunable white luminaire and can adjust from one hue to another, but that’s only half the story …

DOE Evaluates Tunable-White Classroom Lighting

08/21/2019 by Craig DiLouie Leave a Comment

Tunable-white LED lighting offers highly efficient general illumination combined with dimming and the ability to tune correlated color temperature (CCT) from warm- to cool-white. A strong potential application is classrooms, where teachers can set lighting/visual conditions to support classroom activities. In May 2019, the Department of Energy (DOE) published a Pacific Northwest National Laboratory (PNNL) report evaluating a trial installation of tunable-white lighting systems at three classrooms in an elementary school in Folsom, California.
