The BioBulb is a full spectrum daylight bulb that uses 75% less energy than a standard light bulb. The BioBulb issues a massive 1550 lumens (a lumen is a way of measuring natural light, and a standard 60w bulb only manages 600 lumens, so that's over three times as much) and closely replicates sunlight, which may improve mood, nighttime sleep and daytime energy.
Anyone who simply longs for summer may find that its flicker-free white light helps to restore their natural equilibrium. BioBulbs are ideal for reading and most pleasing to the eye, radiates less heat than a standard bulb and lasts around 10,000 hours.
