The average U.S. household includes 51 lightbulbs. Assuming all of those bulbs are 60W incandescents, over 22 years (a common estimate of LED-bulb life spans), you would save roughly $6,942 in energy costs by replacing them with output-equivalent LEDs. Factor in the combined price of the more than 800 incandescents you'd need to stock up on during that period (since most burn out in 1.4 years or less), compared to buying just 51 LEDs, and the total estimated savings for going all-LED comes to $8,639. A number that large is simply too hard to ignore. With all this in mind, we tested dozens of bulbs to find the ones that will help you make the right swap in any socket.
Philips Clear LED Bulb
Best for Resembling an Incandescent
Though companies have figured out how to mimic the colors of incandescents with LEDs, the actual bulbs still look a bit unfamiliar. If you're holding out for that old-school shape, the 40W-equivalent Philips Clear – with its exposed, filament-like lighting elements, and no visible heat sinks – is the LED for you. It's currently priced around $16 overseas, and it's due in the U.S. later this year. [$TBD; philips.com]
