First, check what bulbs you have. Incandescent and halogen bulbs look like the old style bulbs with a glowing filament. Both are hot to touch when turned on because of the energy they waste producing heat. You should definitely replace these bulbs with LEDs as soon as you can.

To find LEDs that match the brightness and color of your current bulbs, make a note of the ”lumens” (brightness) and color (a four-digit number ending in “k”).

CFLs or Compact Fluorescent Lamps (the twisty bulbs) are much more efficient than incandescents, so you should only consider replacing them with LEDs when they burn out.

Once you’ve replaced your light bulbs, make sure you recycle or dispose of your old lights in a safe way - check with your local authorities or hardware store.

Switching to LED lights is a simple and effective way to save on energy bills. LED bulbs might cost a bit more than regular bulbs, but they last up to 20 times longer than incandescent bulbs so you won’t have to replace them as often. You’ll use less energy and buy fewer bulbs, saving you more money over time.

You’ll also cut your carbon emissions. If we all switched our homes to LED bulbs, we could save over 10 gigatons of carbon dioxide emissions - that’s like turning off the world’s coal power plants for a whole year.
