The Bio Bulb™ is a full spectrum daylight bulb that uses 75% less energy than a standard light bulb. The Bio Bulb 60w bulb actually only uses 20w of electricity but is brighter than an ordinary 60w light bulb, putting out a massive 1600 lumens. & the Biobulb closely replicates daylight, which may improve mood, nighttime sleep & daytime energy. Anyone who hates the short winter days & longs for summer may find a Biobulb's flicker-free white light helps to restore their natural equilibrium. Biobulbs are ideal for reading & most pleasing to the eye. They are particularly suitable for people with age-related macular degeneration, as the quality of light makes reading easier. A Bio Bulb daylight bulb also radiates less heat than a standard bulb & lasts around 10, 000 hours, or seven years. One hour spent in the presence of three 60w Bio Bulbs gives the same benefits as an expensive 3000 Lux light box. Length 60w 13.5cm, 60w 12.5cm. Colour rendering index of 85.
