Korrus bulbs are the first circadian lights engineered to work in harmony with nature – not against it.

During the day, it increases the blue light to boost energy, focus, and align your internal clock – just like sunlight. At night, it eliminates blue light, restoring biological darkness – helping your body produce melatonin and ease into deep, restorative sleep. Most artificial lights just change colors and are too weak to fully wake us during the day, yet too strong to ignore after dark.

At Korrus, we purposefully engineer the spectrum itself. Our patented light engines, developed over 10 years and backed by 500+ global patents, manipulate energy output at the nanometer level – removing biologically disruptive wavelengths and tuning in those that promote cognition, rest, and recovery.
