across California will soon be fitted with energy-saving bulbs as the state becomes one of the first in the US to legislate against incandescent bulbs, reports the Associated Press.
Under the laws passed in the state, ceiling lights
must ultimately be fitted with bulbs that consume no more than 72 W of power.
Technologies available to choose from once stocks of incandescent bulbs run out include LED lighting
, compact fluorescent lamps and halogens.
However, the current incandescent bulbs already manufactured by companies in the region can continue to be sold until existing stocks are depleted.
The state began its transition on January 1st, ahead of a nationwide ban on 100 W bulb manufacture starting in 2012.
However, it is not until 2014 that lower power ratings, including 40, 60 and 75 W bulbs, will be banned across the US.
Meanwhile, the EU continues with its phase-out of incandescent bulbs, which began on September 1st 2009 and is due to take until September 1st 2016.
