Tunable White Will Be The Lighting Game Changer of 2015
What is Tunable White?
Tunable white essentially describes a fixture’s ability to shift from “cool” white light to “warm” white. Currently most LED fixtures come in a fixed tone of white light, typical CCTs are often: 2700K, 3000K, 3500K, 4000K, and 5000K. Tunable white fixture offers the ability to shift the tone of the white light. So no fixed CCT is required.
Eliminate the Problem of Guessing What CCT the Client Wants
Vary Color Temperatures Within a Given Application
Task Tune White Light
There is a growing body of research that says that cooler color temperatures of light enhance our alertness and ability to focus, while warmer tones relax us. Imagine an educational environment where you want the students awake and alert for their first class, but a little more mellow after recess. Or imagine an office environment where you want to boost productivity during the work day, but also host social events in the evening. Tunable white offers this variation.
An Example From My Event Lighting Days
I was commissioned a few years ago to design the lighting for the Wired Magazine Pop-Up Store in Times Square. It was a huge space needing light to cover not only signage and walls but all of the latest electronic toys of the day. I was given the design direction that the space needed to feel like an “icy blue white light.” Well what exactly does that mean? I know what it meant for me, but it was the client I was concerned about. I opted to light the space with a color-changing LED fixture rather than a conventional halogen. This enabled me to tune the white light, rather than ask our union electricians to get up on ladders and change theatrical gel on hundreds of fixtures. When my client walked in the door. I asked them for a second to review the lighting. Then moving one slider I was able to add a little more blue to the white light until it was the perfect blue/white tone for them. We locked it in, and they were thrilled.
