The Light Bulb 2.0

The 100 watt incandescent light bulb, standard since Thomas Edison Days, is on its way out by law, January 1. We’ll look at the light to come.

For 400,000 years, human night has been lit by flame. Even Thomas Edison’s incandescent light is, essentially, the light of a burning filament that casts the glow of flame.

But incandescent bulbs are infamously inefficient. On January 1st, by law, the 100 watt incandescent bulb is going away. No more manufacture or import. Then 60 watt incandescent bulbs will go. Then 40.

So what will light our homes? What kind of light? At what price?

This hour On Point: The revolution in lighting. We’re looking at the light to come.

Wired “[LED is] a liquid -cooled bulb, as radically different from Edison’s invention as anything that’s ever been screwed into a standard socket and, [...] the next big thing in the $30 billion lighting industry.”

Consumer Reports “Our tests of 26 compact fluorescents and 10 light-emitting diodes found that though the newest bulbs might not be perfect, they last longer and use less electricity than traditional incandescent bulbs, and many of the problems of earlier versions have been overcome.”
