What's watt in lighting? View our lighting buyer's guide to find out


Are you looking to save a lot of energy at a low cost? Retrofitting your house with LED light bulbs is your best bet. But which bulbs are the best for your home lighting needs? 

Luckily for you, we’ve done the research and compiled the relevant information into this Lighting Buyer’s Guide. We’ll teach you about the benefits of LEDs, how to compare features and options, and what instant rebates are available to make your purchase a better bang for your buck.



  • Set It and Forget It - Most LEDs last between 18 and 46 years (when used for three hours per day), which is 10 to 25 times longer than incandescent bulbs and two to three times longer than CFL (compact fluorescent lamp) bulbs.
  • Reduce Energy Consumption - Over the life of the bulb, LEDs use up to 90% less energy than incandescent bulbs and up to 10% less than CFLs.
  • Save Money – These energy reductions save you $30 to $80 in energy bills over the life of each bulb when switching from incandescent to LED lighting.
  • High Quality - Provide the same brightness (lumens), with less energy use (watts).
  • Green Benefits - LEDs lack dirty components, such as CFL’s mercury, and help protect the environment and prevent climate change.



There are a number of factors to take into account when choosing the right LED light bulbs for your home. We've included the five key factors below.


LED bulbs come in a variety of shapes and sizes. Here are a few of the most popular uses for the light bulb shapes offered on the Your Energy Savings Store:

  • Table or Floor Lamps: A-line bulbs 
  • Wall Sconces: A-line, globes, and candle / torpedo bulbs
  • Pendant Fixtures: A-line, globes and candle / torpedo bulbs
  • Ceiling Fixtures: A-line and candle / torpedo bulbs
  • Ceiling Fans: A-line and candle / torpedo bulbs
  • Recessed Cans: Spot or flood bulbs
  • Track / Accent Lighting: Spot bulbs

Brightness & Color

  • Brightness: It's a common misconception that watts equates to brightness, when in fact lumens is the correct measurement of light output (watts instead indicates power). For those wishing for high brightness levels (lumens) with low energy usage (watts), look for a high efficacy number (lumens per watt). 
  • Color: Most bulbs make it easy to compare light colors by associating a label along the "Warm" to "Cool" spectrum. To get more specific, search for a light color temperature on the Kelvin scale (K). Lower Kelvin temperature means warmer, yellow/white light, while a higher Kelvin means cooler, bluer light. Here are some hints to help you out:
    • A Warm White / Soft White (standard color of incandescent bulbs and are good for bedrooms, living rooms and dens) color ranges from 2,700K to 3,500K.
    • Cool White, Natural White (good for kitchens, work spaces and bathrooms) ranges from 3,500K to 4,100K. 
    • Natural or Daylight (good for reading) ranges from 5,000K to ~6,500K. 

Savings & Life Rating

  • Savings: 
    • Energy Savings: LEDs use up to 90% less energy than incandescent bulbs and up to 10% less than CFLs.
    • Bill Savings: Save $30 to $80 in energy bills over the life of each bulb when switching from incandescents.
  • Life Rating: Most LEDs last around 25,000 hours, which is 10 to 15 times longer than incandescent bulbs and 2 to 3 times longer than CFL bulbs. Put into years, LEDs typically last 18 to 46 years. 

Base Size & Fit

    • All LEDs on the Your Energy Savings Store list the base size relating to the appropriate fixture. 
  • Remember to always check packaging for proper use.

Industry Classification

All LED light bulbs on the Your Energy Savings Store have earned the ENERGY STAR ® label, which requires extensive testing and certification to ensure they will save energy. The ENERGY STAR standard includes:

  • Color Quality: consistent light over the rated life (lifespan) of the bulb.
  • Light Output: Light meets minimum levels for replacement claims and is maintained through the end of rated life.
  • Efficacy: ENERGY STAR ® certified bulbs use more light (lumens) for less power (watts).
  • Warranty: Three-year minimum warranty for bulbs with a life rating of greater than or equal to 15,000 hours.
