Incandescent era, RIP. Like it or not, it's time to move on. Traditional incandescent lightbulbs are gone-not banned, precisely, but phased out because the Power Independence and Safety Act (EISA), handed in 2007, requires them to be about 25 p.c more efficient. That is inconceivable to realize with out lowering their luminous flux (brightness), so, as a substitute, manufacturers have shifted to more vitality-efficient applied sciences, similar to compact fluorescents (CFLs), halogens, and LEDs. Of course, not everyone seems to be embracing these next-gen lightbulbs. Some surprise why we'd like a mandate to make use of them, in the event that they're so nice. The actual fact is, after more than a century of incandescents, we've grow to be attached to them. They're cheap, they dim predictably, they usually emit a warm and familiar glow. Weaning ourselves off them won't be straightforward: Simply as the 40- and 60-watt phaseout went into effect on Jan. 1, about half of the 3.2 billion screw-base bulb sockets nationwide still housed incandescent bulbs.
