"The BioBulb® is a full spectrum daylight bulb that uses 75% less energy than a standard light bulb.
The BioBulb® 100w (using 25w) bulb issues a massive 1750 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 prone to Seasonal Affective Disorder (SAD) or who simply longs for summer may find that its flicker-free white light helps to restore their natural equilibrium. They are ideal for reading and most pleasing to the eye. Our BioBulb® also radiates less heat than a standard bulb and lasts around 10,000 hours. Length 100w 13.5cm, 60w 12.5cm. Colour rendering index of 85. Available in Bayonet and Screw fittings." Ecozone
