"According to the package for the LED bulbs I installed when I bought my house
three years ago, I shouldn't have to change a lightbulb until my kids are
grown, college-educated — and perhaps even married and having kids of their
own.
That's because today's LED bulbs claim a lifespan of up to 91 years. Install a
bulb today, the packaging suggests, and you might be passing it on to multiple
generations of descendants.
The reality, in most cases, is completely different. Despite their outrageous
claims, many LED bulbs last only 4–6 years in real-world use.
Half of the fancy LED bulbs I bought three years ago have already burned out.
Even more annoyingly, many of the expensive LED bulbs I bought for track lights
on my 18-foot ceiling have died as well.
Today's LEDs often fail to deliver on their promises. This harms consumers and
the planet. And it's about to get worse. A new Federal law went into effect on
August 1st that requires bulbs to emit at least 45 lumens per watt of power
used. Although it's not officially an incandescent ban, the law makes efficient
lightbulbs like LEDs a de-facto requirement in the United States, and most
incandescent bulbs will no longer be eligible for sale.
Why the huge discrepancy between advertised lifespans and reality? There are
several factors at play. Understanding them is key to navigating the LED
transition in a way that makes use of potentially world-changing LED technology
without leaving consumers angry — or damaging the planet."
