“Light used in the evening (during the three hours before bedtime) should have as little blue content as practically possible.”

– Consensus of 248 leading circadian scientists

Take immediate action by replacing you light bulbs in your bedroom and in other places where you spend evening hours with zero blue light bulbs. (<2% 440-495 nm blue)

Fully Automatic Circadian Light Bulbs

The A-19 and BR-30 OIO circadian light bulbs, just released by Korrus, automatically cycle through three spectral recipes depending on the time of day. There is a MaxBlue spectrum, which delivers the >20% sky-blue light at the times required to sync the circadian clock, a warm white ZeroBlue light for doing useful work in the early evening, and a 1400K orange-red light for winding down before going to sleep.
