"I love LED bulbs," Carolla says. "Forget about the compact fluorescents – that's going to be the 8-track of this new generation. Weird little knobs, like a little novelty item that existed in between records and CDs or cassettes."
LED bulbs are great for outdoor lighting and last 10 times longer than fluorescents. They are also the safer choice because they have to be replaced less often, which means you'll have fewer opportunities to fall off a ladder. The only downside is the price. Carolla says to "bite the bullet."
"You do it once, then walk away," he says. "It saves a ton of electricity."
