LED lightbulbs have been game changers, with some promising to last anywhere between 23 to 46 years. But some of these bulbs may actually do more than just light a room. Several of them claim to help you fall asleep faster, wake up more alert and do other fun tricks.

The Definitely Digital Good Night LED claims to improve your natural sleep because it emits less blue light than other LEDs. Although any light can suppress melatonin, the hormone that facilitates sleep, the human eye is particularly sensitive to blue light.

Using a machine, Consumer Reports measured the amount of blue light in the Good Night bulb and found it does have lower levels of blue light than other LEDs. But is that worth its $70 price tag?

“Try a CFL. It costs a lot less than an LED and it gives off a lot less blue light,” said Kimberly Janeway of Consumer Reports.

Janeway recommends Walmart’s Great Value Soft White 60-Watt Replacement CFL at just over $1 per bulb.

If you have trouble sleeping, health experts suggest turning off all sources of blue light such as smart phones, computer and tablet screens and TVs several hours before you turn in.

Consumer Reports also tested the $70 Definitely Digital Awake and Alert. It claims more blue light for improved alertness. The tests found it does deliver higher blue-light levels, but the light color is not all that flattering to your skin.

And Consumer Reports tested the LIFx LED bulb, which is supposed to help keep you awake and alert. It connects to your Wi-Fi and can be controlled using your smart phone. It changes color and even has a strobe-light setting. But if you just want to light a room, the $99 price tag is a lot to pay.

Instead, testers say the Cree A19 Soft White Dimmable LED will light a room just fine for $8.50 per bulb.
