As you probably know, LED bulbs are one of history’s
greatest high-tech success stories. They use around 90 percent less electricity
than incandescent bulbs, yet last 25 years or more. They turn on to full brightness
instantly. They remain cool to the touch. They’re hard to break, and
safety-coated if they do.
The smart-bulb revolution began a few years back, when companies started
making bulbs that you can control with a phone app — turning on and off,
dimming them, and even changing the color.
In the last few months, though, some even brighter
ideas in light bulbs have heated up.

And its technology is so amazing, you may not believe it.
At its heart, the SmartCharge 2.0 is a battery-backup bulb
designed to work when your power goes out. It’s the size of a normal bulb, so
you can screw it into any lamp or fixture. Compared with other smart bulbs,

But here’s where your mind will fall apart. Read this slowly:
