What to know about the new energy efficiency law for lightbulbs

Try out Xcel Energy’s new and improved Bulb Finder to find discounted LEDs near you.

Last year, the U.S. Department of Energy announced the phaseout of energy-wasting lightbulbs, banning the manufacture and sale of most standard incandescent and halogen lightbulbs. As of August 2023, these bulbs have been removed from retailers’ shelves and you will no longer find them in stores.  
Lightbulbs are now regulated to both conserve energy and help consumers save money on energy bills. LED bulbs are more efficient at lighting homes than incandescent and halogen bulbs. The new standard requires that lightbulbs produce 45 lumens per watt, while the traditional incandescent bulb produces 15 lumens per watt. These new standards are saving consumers money on energy bills. An ENERGY STAR® LED bulb saves about $55 in electricity costs over its lifetime and lasts at least 13 years. 

Xcel Energy offers huge discounts on energy-efficient LED light bulbs to customers, along with a quick and easy way to find participating locations on our new and improved bulb finder tool on the Xcel Energy website. Find LED light bulb prices as low as 8 cents in Minnesota, Colorado and New Mexico, 16 cents in Texas and 25 cents in South Dakota. Enter your zip code in our bulb finder tool to find stores close to you that offer LED bulbs at our deeply discounted prices. Xcel Energy provides discounts of up to $3 per bulb in these five states; bonus discounts of over 80% are available in select areas. 
Our discounts are at many retailers, including Batteries Plus, Costco, Dollar Tree, Home Depot, King Soopers, Lowe’s, Menards, Salvation Army, Sam’s Club, Target and Walmart. They can also be found periodically at Goodwill, Habitat ReStore and Walgreens.  
Not sure what to buy?  

Download the helpful LED bulb guide that will help you determine which shape, size and color temperature to buy to replicate the old bulbs you’re replacing. The higher the output in watts or lumens, the brighter the bulb. 
Colorado Customers and Employees: 
Be sure to act now using the convenient Bulb Finder, as many large retailers will only offer our deep discounts until October 1, 2023. All other states are not affected by this limited-time offer, as it is Colorado-specific. 
The discounts are funded by Xcel Energy’s Demand Side Management programs, created to help customers save energy and money through a variety of programs and services. 
The Bulb Finder feature and its participating stores is currently available in Minnesota, Colorado, New Mexico, South Dakota and Texas. Wisconsin residents can participate in the statewide Focus on Energy program. Find discounted bulbs at
