Mercury News:  The light bulb police in action.  “Californians can start saying goodbye to traditional 100-watt incandescent light bulbs now that the state has become the first in the country to require a new standard for the screw-base bulbs.  Experts say the new rules, which took effect New Year’s Day, will save residents money and energy. . . . what used to be a 100-watt light bulb manufactured and sold in California will have to use 72 watts or less. . . . Similar new standards for traditional 75-watt, 60-watt and 40-watt incandescent bulbs will go into effect in California over the next few years, with wattages reduced to 53, 43 and 29 respectively.
