Light energy in this wavelength band promotes alertness. In this article, we discuss the health impacts of the light emitted from LED lights - in particular, "blue light" as it relates to the LED spectrum, as well as the effect of flicker that is prevalent in LED lights.įigure 1: Graph showing the sensitivity curve for melanopsin response. There exists very little, however, in the way of understanding or regulations for the quality and safety of the light emitted from LED bulbs. Most governmental authorities have continued to adapt existing building and safety codes to prevent fire and electric shock risks - and of course, it is always a smart idea to always practice basic electrical safety. LEDs are of course energy efficient, last many times longer and are therefore preferable from an environmental standpoint, not much is mentioned with respect to the human and consumer side of things - especially when it comes to the safety and health effects of the emitted light itself.Įlectrical and toxicity concerns of LEDs are generally in line or superior when compared to incandescent and fluorescent lamps. LED lights are rapidly becoming the standard lighting technology in many applications, and in many areas have become the only option as incandescent and CFL lighting options become phased out.
