Start saving energy with this bright idea: Replace your bulbs.

imageSo, you’re thinking about updating your home’s light bulbs. Good for you! That’s a great way to help lower your home’s energy usage. But, choosing the right bulb can sometimes feel like alphabet soup. Here’s a quick way to remember the benefits of updating your light bulbs with ones that use 75 to 85 percent less energy:

Light-Emitting Diode bulbs (LEDs)

  • Outperform and use slightly less energy than CFLs
  • Instantly brighten, indoors and out, despite cold outdoor temperatures
  • Longer lifespan than CFLs, regardless of frequently turning them on and off
  • Low heat emission, thereby not raising the room’s temperature
  • Fully dimmable
  • Direcational light source, meaning LEDs emit light in a particular direction

Compact Fluorescent Lamps (CFLs)

  • Long life
  • Use less energy than incandescent and halogen bulb
  • Soft white light available
  • Contains minor amounts of mercury
  • Most CFLs do not work with dimmers

Other benefits:
Better for Our Planet. According to, if every home in America replaced just one incandescent light bulb with an ENERGY STAR qualified CFL, we would save enough energy every year to light 3 million homes and prevent greenhouse gas emissions equivalent to those from about 800,000 cars.

More affordable now. Energy-saving lighting can feel more expensive at checkout when compared to the cost of incandescent bulbs. But, keep in mind that the overall cost of LED bulbs and CFLs have significantly declined in recent years — down 85% since 2007. Plus, you won’t replace them as often as incandescents.

You might want to update this article based on recent developments at MIT where they have developed new incandescent bulbs that are more efficient than either LED or CFL and will be much cheaper to make.
You may not want to replace all your incandescents just yet.

    Thank you for your feedback. Right now, we’re hoping to steer customers to the energy-efficient choices currently on the market. But, we’ll look forward to new advances in technology so that we can have even more options in the future!

I replaced most of the bulbs in my house several years ago with CFLs, but have discovered they don’t last anywhere near the advertised 10,000 hours. Many have had a shorter life than the incandescent bulbs they replaced.

You did not comment on the fact that some (maybe all?) CFLs and LEDs cannot be used in an enclosed globe – like the ceiling light on my front porch. One needs to be careful to read all the fine print before one buys any bulb!

    Thanks for the feedback, Dunstan. That’s a good point about reading the fine print.

I,have the led lights.

Barbara Smith - 2/12/2015

Thanks, I’ve already switched bulbs years ago! All my appliances are new within the last five years and are energy efficient. Anything to save on energy! By the way, Ive just begun my second year with Constellation.

would like to know why I no longer have Constellation delivering my gas when I have a contract with both JCPL and New Jersey Natural Gas….not sure what exactly caused all the problems.
