BLUblox has spent 12 months researching and developing two optimal light bulbs to transform your light environment. Meet Lumi SummerGlo and Lumi Sleep+. Lumi SummerGlo is the perfect low blue light bulb for daytime use. Lumi eradicates the nasty blue LED light spike at 465nm that could be causing digital eyestrain and headaches at the end of the day. Lumi 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. Lumi light 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.
