U.S. ban on incandescent light bulbs takes effect today — what you need to know
A Department of Energy rule set last year and effective beginning Tuesday bans the manufacture and sale of what the department has deemed inefficient “general service lamps.” That’s the official way of saying standard light bulbs screwed into lamps and ceiling fixtures, mostly in homes. You might picture a slightly updated version of Thomas Edison’s 1870s patent, although still with a thin coil of wire called a filament. And you’d be correct.
It’s a bulb type that consumer groups and environmental advocates say saves money and energy, largely because traditional bulb styles, unlike LEDs, don’t turn the electrical energy they use directly into light, but first into heat. There’s a reason a toy Easy-Bake Oven, powered by a bulb, turns out a small cake.
And even those upfront prices are coming down. The Energy Department has said that the average cost of LED bulbs has dropped by nearly 90% since 2008. And despite initial sticker shock and for the most part, a range of options, LED sales have increased even before the regulatory changes. Globally, residential-only LED sales had increased to about 50% of sales in 2022, up from just 5% of the market in 2013, according to the International Energy Agency. Home-furnishings chain Ikea, for one, had switched to selling only LEDs as of 2015, including in U.S. stores.
The Natural Resources Defense Council offered different figures: LEDs use one-sixth the amount of energy to deliver the same amount of light and last at least 10 times longer than incandescent bulbs.
