They burn brighter, longer, and use less energy.

No, actually it's true, but with an * after it. They are essentially round fluorescent light bulbs and have the same characteristics. If you turn them ON and leave them ON for long periods, they use considerably less than incandescents. It you turn them ON and OFF frequently, they use more.
That's why they make no sense in bathrooms, closets or other places that are only lit occasionally (that's why you won't find them in those places in our house).
They do burn brighter per watt, but typcially people will use lower watt “green” light bulbs in the same fixture to get the same amount of light they got with the old style bulbs. I presume they do use less energy, as that claim could easily be proven or disproven.
In my experience they don’t last longer than the old ones, are at least not nearly as long as the Greenists try to claim.
I am stocking up on the old bulbs.
The first claim is debatable. The second claim is correct, as is the third.
