Blue Light and Circadian Rhythm

There has been a well researched and established understanding of the effects of blue light exposure and the effects to the humans circadian rhythm. The full consequences of this (apart from maybe not sleeping so well) are still being understood. Not staring at a screen before you go to bed, and applying blue light filters to those screens after the sun goes down is a good idea.

But what about the LED lighting up your home? The thing with LED light is it is artificially created, it uses bits of the visible light spectrum, including quite a lot of blue light to blend and create the desired color temperature. Compare this to our not so distant past, which relied on fire to light the evenings; there is not much blue light there.

A product by Soraa creates your desired color temperature but cuts out the blue light.. How is this possible.? It adds additional light into the ultraviolet spectrum (ultra blue), skips the blue and provides a blend of the remaining visible spectrum, which is un-noticeably different from any other LED, but without the circadian effecting blue light spectrum.

The question which remains is: will this be the next development in LED, or just another fad...
