Great daylight balance, poor longevity
on 14 July 2011
This bulb gives a great daylight balanced light that makes the indoors look much more like the outdoors! At first, this takes a bit of getting used to if you have previously used normal energy-saving bulbs. But after a while it becomes very natural and is great for reading.
However, I must comment on the poor lifespan of the bulb. Mine was purchased in October 2010 and stopped working in July 2011. Compared to normal energy saving bulbs that usually run for 5+ years - and cost a small fraction of a Biobulb to buy - this is very disappointing. A colleague at work also had a Biobulb fail within a year. Read the reviews of the bayonet fit Biobulb and several people complain of getting less than a year's use from them too.
I'm now deliberating on whether to buy a replacement. I love the quality of light, but I just expect it to last much, much longer. So much for 10000 hours lifespan!
