If you’re ready to take the plunge into LED lighting, this 6-pack of highly-rated TCP daylight bulbs is down to just $18 on Amazon right now, one of the best per-bulb prices we’ve ever seen. They aren’t dimmable, so you won’t want to put them in certain fixtures, but it’s a great bulk pack for filling out ceiling lights and lamps throughout your house.
Once you’ve got them, check to see if your local utility company offers rebates for purchasing LEDs. If so, it’s possible these could pay for themselves even quicker than they would otherwise. If you prefer a warmer bulb, the equivalent LED bulb soft white pack is just a couple bucks more.
