The evolution of the US light bulb market has been nothing short of spectacular. The share of the market held by the incandescent bulbs we all grew up with fell from 68% in 2010 to less than 6% just six years later.
Now, the experts predict that increasingly inexpensive LED lights will soon sweep the market and change everything once again.
These changes in basic household lighting have brought about enormous changes in energy usage. For the first time in decades, household demand for electricity has fallen.
The next phase of the lighting efficiency rules are supposed to kick in next year after which only compact fluorescents and LEDs will qualify. However, the industry has appealed the ruling and the anti-regulation Trump administration will probably delay the change.
