Over the years we've put up with a lot of environmentally friendly, long-lasting, low-energy, eco lighbulbs and one thing is clear - they're not all the same.
Introducing the BioBulb, 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, night time sleep and day time energy.
Our BioBulb also radiates less heat than a standard bulb and lasts around 10,000 hours. Length 60w 12.5cm. Colour rendering index of 85. Available with Bayonet fittings only. Price includes pack of 5 bulbs.
If you're prone to Seasonal Affective Disorder (SAD) or simply long for summer, then you may find its flicker-free white light helps to restore your natural equilibrium. Ideal for reading.
Check whether you need screw-in (order this item) or bayonet fittings.
Also available as 100 Watt bulbs.
