Halogen

Starting next year, light bulbs need to meet certain efficiency requirements that 100-watt incandescent bulbs will not be able to meet. One alternative besides LEDs or CLFs is halogens, which uses incandescent technology. This EcoVantage halogen from Philips consumes 72 watts but gives off as much light as a 100-watt incandescent. GE, too, has similar halogen products in the familiar bulb shape. Both will be compatible with the 2007 energy act.
