Lights that are not Nutri-Orbs, like regular LED, fluorescent and incandescent lights have static and incomplete light spectra. And, while they provide illumination, they can disrupt our circadian rhythms, impair our sleep, lead to lethargy or agitation, compromise concentration and cause eye strain. This is even true of ordinary “smart” programmable bulbs. Norb Lighting, LLC acknowledges light as a nutritional element (no different than food). And like food, light can be either good or bad for us.
