Now that countries are banning traditional lightbulbs, they're discovering that the replacement is not up to the task.

They also contain mercury which is a disposal hazard. I understand the total costs for lighting in the average home is only 10% of the electric bill costs. Another thing I dislike about these bulbs is that they won't work with a dimmer in addition to the warm up time to get to full brightness. Lastly, fluorescents don't hold up well to being turned on and off. Their lives are short if you cycle the switch too often.
I wish they would perfect the LEDs.

Amen with the LED's. Another thing that Congress apparently did not know or think about when banning, there are some applications where the 75 watt incandescent bulb was superb, like heating one's well house in the winter --oh yeah, they don't know what a well house is. I forgot. Probably don't know what a 2-holer is either. I can't wait until the day they write a federal law against septic tanks--its coming I know, because some states/municipalities have already banned them, but the cost of other systems in rural areas are prohibitive a lot of the time.

They also don't light up as fast which isn't so bad in the bedroom in the morning, but not so good for security lighting. They also have a flicker that bothers some people while others don't notice. And they don't put out any heat which is good much of the time, but not so much other times.

The flicker definitely irritates me -- to the point that at work I leave the light off and work by the light from my window when I can get away with it. Practically every day people are going past asking "why are you working in the dark?"

I also own stock in CREE, a company working to perfect LED lighting.
