With their rainbow of hues and myriad party tricks, color-tunable LEDs get all the press in the world of smart lighting. It's fun stuff, but the reality is that most of us will rarely find much of a need to turn all the lights in the house blue or red—unless it’s time to celebrate our team winning the World Series. Even then, you’ll probably want to turn them all back to white after the celebration. And with our review of the Stack BR30 Downlight Starter Kit review, we discovered there are varying degrees of smart when it comes to smart lighting.
White light is also important in its own right, as today there is plenty of science to show how various shades of white—with variations in color temperature—impact our psychological state. Cool light that's closer to blue has an energizing effect, and is best in the morning. Warm light is relaxing, and is best after the lights go down. If, like a growing number of us, you work where you live, chances are you don’t spend any effort switching bulbs out twice a day in order to optimize your lighting environment.
