Today I picked up a daylight biobulb and I must admit that im impressed, I used to have just a normal 60w bulb, but this biobulb puts out way more light and its a much brighter light as well, I like it :)
Some pictures to show difference, I might have to take some further away to give sense of the difference in the luminosity, the pictures dos not totally justify the difference between the two, and it is huge.
The pictures were taken using only the bulbs, no extra light no blitz no nothing.
