Bush (you remember him) signed an Energy Bill that, among different things, meant to make America extra power environment friendly. It included laws that might end the manufacture of wildly inefficient lightbulbs. Some political shenanigans ensued, but the quick version is that in 2012, the phaseout of conventional incandescent bulbs started, starting with the 100-watt varieties.

Forget your cold blue expertise of yesteryear and look into the array of options available at the moment, lots of that are coated on this helpful New York Occasions evaluation.
