A German entrepreneur is bypassing a European Union ban on light bulbs of more than 60 watts by marketing his own brand as mini heaters.
Siegfried Rotthaeuser and his brother-in-law have come up with a legal way of importing and distributing 75 and 100 watt light bulbs -- by producing them in China, importing them as "small heating devices" and selling them as "heatballs."
The heatballs are very efficent - 95% of the energy is converted into heat. However they also emitt light as a waste-product. ;)
