bulbs, including halogen types, are energy hogs: Typically emitting as light only 5 percent of the energy they use, they convert the rest to heat.
According to the ministry of industry, the country has 22 companies producing electric lamps altogether with an annual capacity of 1.18 billion units including 842.6 million of incandescent
lamps and 334.9 million of TL.
By comparison, incandescent
bulbs cost about a dollar each, although prices will probably increase as they become scarce because of the government requirement.
Filament LEDs could also solve a problem for policymakers who have long desired to ban inefficient incandescent
bulbs, over the objections of consumers who prefer the old-style look.
Australia banned the sale of "wasteful" incandescent
light bulbs in 2009, and Argentina did the same the following year.

But by 1878 he had cracked it, and gave a demonstration of his incandescent
carbon lamp at a meeting of the Newcastle upon Tyne Chemical Society--and then many subsequent lectures across the country, including one at the Literary and Philosophical society of Newcastle, where more than 700 gathered to see his invention.
Additional factors, like more stringent energy codes, increases in the cost of electricity and a renewed interest in sustainable building design, have also contributed to the development of more efficient light sources, especially screw-in LED bulbs that can be used as direct replacements for incandescent
