Compact fluorescent lamp

Energy saving light bulb I just bought is 6 times the cost of a normal bulb.

 

The brand is www.kosnic.com/ It says it is "protected by patents". Is that why the cost is so high I wonder? Patents?

This is a new one which is much better than the previous CFL pictured here:
