Traditional 40 watt and 60 watt incandescent bulbs will be a thing of the past, effective January 1, 2014. This is because a bill was passed in 2007 making it illegal to import or manufacture inefficient incandescent bulbs after this date. In a drive to rid their six month stockpile of incandescent bulbs, the Home Depot is urging consumers to stock up on them before they become obsolete.
Under the 2007 law, incandescent bulbs can still be manufactured, but manufacturers will have to make improvements in terms of the wattage that they draw. If manufacturers undertake improvements, 40w bulbs will have to consume 10.5w and 60w bulbs should draw 11w.
Though CFLs and LEDs reduce power consumption and last longer, many people favor incandescent bulbs over them because of the light that they emit as well as the affordable price. Some interior decorators even started hoarding incandescent bulbs from as far back as 2010, in light of their impending discontinuation.
