Regardless of the ultimate veracity of this (health guidance is …), there's still a benefit. So many shops have switched to selling "LED lighting," without distinguishing the quality. So there is a lot of harsh lighting being sold, that lasts a long time, which is a shame because colour temperature really does have a big effect. I was subjected to this in a lighting shop, where I was requesting fixtures that took a standard bulb, so I could plug in my own LED bulbs with controllable colour temperature, but the salesperson just couldn't see how that was better than their integrated LED systems.
