With so many technological advancements in linear lighting these days, it can be difficult to keep up. However, one thing is for certain: Tunable lighting and controls are quite the hot ticket for lighting designers and architects. Light and color have gone hand in hand since the dawn of time, so it makes sense that manufacturers and the lighting industry are fully embracing this development - especially since it means you can change the mood of a room or its occupants with a simple turn of a light knob.
Like so many other things - TV listings, flights, trains and appointments - your body operates on a clock. Experiencing that sluggish feeling after jet lag and Daylight Savings Time happens for a reason, and it all has to do with our circadian rhythm.
Artificial light has created more "time," so to speak, for all of humankind to get things done. We can work whenever we please, carry on business 24 hours a day if needed. However, as animals who have spent millennia living by the rhythms of the sun's rays, this artificial option has definitely taken a toll on some individual's health and personal well-being.
Because 8-hour day and night shifts are not going to stop anytime soon, the solution must come from the lighting source itself: In comes tunable lighting.
The sun doesn't provide the same level or even color of light throughout the day, so sitting under the same white light in an office, hotel or school can make you tired when you need to stay awake, or, conversely, too wound up when your body should be starting to relax. Tunable lighting mimics that natural ebb and flow of sunlight, working more symbiotically with your own circadian rhythms.
