New Lighting Standards in 2012

As part of the Energy Independence and Security Act (EISA) of 2007, the "light bulb law" is designed to remove unnecessarily wasteful products from the market. Under the new standards, screw-based light bulbs will use fewer watts for a similar lumen output. Any type of bulb can be sold as long as it meets the efficiency requirements. Common household light bulbs that traditionally use between 40 and 100 watts will use at least 27% less energy by 2014. The law applies to the manufacture date and began affecting 100-watt bulbs in January 2012 and will end with 40-watt bulbs in January 2014. Based on U.S. Department of Energy estimates, with the new EISA standards, U.S. households could collectively save nearly $6 billion in 2015 alone.

Increasing your lighting efficiency is one of the fastest and easiest ways to reduce your energy costs. Fortunately, the variety of energy-efficient lighting options continues to grow. You can choose from a wide range of bulbs depending on what works best for your needs and budget.

Lumens and Watts

Efficiency is measured by the number of lumens per watt a bulb provides. Lumens tell you how bright a light is, while watts tell you how much energy the bulb uses. For example:

  • The standard 60 watt incandescent light bulb provides 13 to 14 lumens per watt.
  • An equivalent CFL provides between 55 and 70 lumens per watt.
  • An equivalent LED can range between 60 and 100 lumens per watt.

Lighting Tips

  • Turn off lights when leaving a room.
  • Use "task" lighting so work and leisure activities can be carried on without lighting up an entire room.
  • Choose lighter colors for walls, ceilings, floors and furniture since dark colors require higher lamp wattage for illumination.
  • Locate floor, table and hanging lamps in the corner of a room where they can reflect light from two wall surfaces and give more usable light.
  • Clean lighting fixtures regularly. Dust on lamps and reflectors impairs lighting efficiency.
  • Make sure that outdoor lighting is turned off during the daytime by installing photoelectric controls or timers.
