Flourescents are so totally old-school. These days, energy-saving cool-kids are turning to LED. (That's light-emitting diodes for those not in the know). Word on the street is that these lights can stay bright for up to 50,000 hours, and those that come with metal heat sinks even absorb heat instead of emitting it. Unlike flourescent bulbs, which contain mercury, LEDs dont's contain any hazardous waste, and when they've got no light left to give, they simply fade away instead of burning out.
