I purchased my first CFL shortly after they were widely available in stores, so more than a few years have passed. After experiencing good results with that bulb (until it finally burnt out), I decided to continue with a CFL. I am surprised how much better this new bulb is. The full brightness occurs a lot faster, and the bulb, especially the base, remains cooler than the old bulb did. Factor in the energy savings, and I am extremely pleased with my choice.
