Lighting. It’s not as sexy as electric cars, solar thermal plants or biofuels, But it’s a key component of greentech. Kaj de Daas, chiarman of Philips Lighting North America (a subsidiary of Royal Philips (NYSE:PHG)), provided an overview of the lighting market at the Dow Jones Alternative Energy Innovations conference today and here’s what he said.

  • $75 billion: the overall size of the global lighting market. The U.S. accounts for 20 percent of the total. (Philips does about $3.5 billion a year.)
  • 52: The average number of light sockets in a U.S. home. Put another way, there are 4 billion screw-in light sockets in this grand land of ours. Although the U.S. is the largest market, it’s the slowest when it comes to adopting new technologies.

  • 5 milligrams: The amount of mercury in a compact florescent.

  • The Whole Enchilada: LEDs can last 50,000 hours. Thus, light bulb makers will lose their replacement market when LEDs go mainstream. The solution? Philips is shifting to making entire lamps and light fixtures. “I
