"If it's been a few years since you shopped for a light bulb you might find yourself confused. Those controversial curly-cue ones that were cutting edge not that long ago? Gone. (Or harder to find.) Thanks to a 2007 law signed by President George W. Bush, shelves these days are largely stocked with LED bulbs that look more like the traditional pear-shaped incandescent version, but use just one-fifth the energy.

A second wave of light bulb changes was set to happen. But now the Trump administration wants to undo an Obama-era regulation designed to make a wide array of specialty light bulbs more energy efficient.

At issue here are bulbs like decorative globes used in bathrooms, reflectors in recessed lighting, candle-shaped lights and three-way light bulbs. The Natural Resources Defense Council says that, collectively, these account for about 2.7 billion light sockets, nearly half the conventional sockets in use in the U.S."
