We are all doing this, but shouldn't : mercury!

The US and rest of the developed world have a huge infrastructure in mercury fluorescent lights because of steps already taken to reduce energy usage. Every time you throw one away, a few drops of mercury are added to your local landfill, hundreds or thousands of tons every year. Despite the obviousness of this rhinocerous-in-the-corner environmental problem, no one has wanted to point for decades because the logistical nightmare of disoposing of all these hundreds of millions of long fragile glass tubes (and now hundreds of millions more little spiral tubes with standard bulb bases).

Cheaper polymer-based LEDs for normal lighting use is a wonderful development, assuming it lives up to its hype. The people who won't be happy are those who had been busily putting the world's massive overstock of mercury which is no longer used in commercial plants to produce sodium hydroxide and bleach.
