LED fluorescent lamps:

"It is compatible with virtually every standard, ballast equipped fluorescent light fixture, without any need for modification."
With LED daylight lamp, 20% energy use reduction versus standard fluorescent tubes. And also there is no mercury or lead in these replacements, and that they do not have a breakage hazard as do standard glass tubes.
