The evolution of the light bulb.

  1. The incandescent got a bad rap - yes, it uses more energy, but you can create a near vacuum bulb that could last a very very long time ( EG. firehouse lightbulb that's been burning since 1910 ) but planned obsolescence wins here. The fluorescent bulbs and cheap LED Never last their given rating, maybe 10% of their wishful-thinking life rating. LED wins for wattage used and hoping in the near future their popularity grows and then they can too become less expensive. My 2¢
