Circadian Light - Key Discoveries

The problem is that the 440-470nm blue light emission spike of these widely sold blue-pump LEDs causes maximum stimulation of the melanopsin retinal ganglion cell receptors and the non-visual pathways controlling the circadian timing system and pineal. Because of these spectral characteristics these conventional blue-pump LEDs are much more potent suppressors of pineal melatonin with its attendant disruptive health effects. With LED lighting projected to replace over 50% of the workplace lighting by 2020 we have an impending catastrophic collision between technological advance and human health and well-being.
