Bon Charge has spent years researching and developing two optimal light bulbs to transform your light environment. Meet SummerGlo and Sleep+. SummerGlo is the perfect low blue light bulb for daytime use; it eradicates the nasty blue LED light spike at 465nm that could be causing digital eyestrain and headaches at the end of the day. Sleep+ eliminates 100% of all blue and green light between 400-580nm allowing you to unwind in the evening and prepare your body for sleep. Both bulbs are LED but do not flicker, they are low EMF and have a long lifespan, making them the world’s first optimal circadian lighting solution for our modern world.
