It may be impossible to replace sunlight, but GE Lighting, a Savant company is taking a stab at it with its new “sun filled” LED bulb, introduced to help maintain the body’s circadian rhythm, which in turn can support energy levels during the day and restful sleep at night. The bulb delivers a high-CRI value of 97 to render colors that look much like they would appear in natural sunlight, and emits a spectrum that is closer to sunlight than ordinary LEDs by eliminating the 450-nanometer wavelength (the blue spike) present in many artificial light sources. Without the invisible blue-spectrum peak, there’s also no need to adjust the color temperature of your lights when you’re ready to unwind for the evening—an added perk for those who usually do so.
