SkyBlue® A21 is an LED retrofit bulb, powered by BIOS SkyBlue® patented circadian technology.BIOS SkyBlue® emits specific wavelengths that provide the same circadian benefits of the sun during a 24-hour period.
During the daytime, it infuses the critical sky-blue spectrum (490nm) to enhance productivity and boost mood. For your safety, the SkyBlue® technology emits minimal light in the blue light hazard region associated with retinal injury.
At nighttime, the SkyBlue® A21 bulbs have a dimmable capability to dim to zero blue. This removes the sky-blue spectrum and creates a warmer atmosphere that promotes natural melatonin production and better sleep.
