Ambit Energy Reviews the Top LED Replacement Bulbs
Ambit Energy anticipates more and more homeowners will switch to LED light bulbs as prices start to drop, making them more affordable. Due to the rising popularity of LED bulbs, Ambit Energy has compiled the accompanying list of the top LED replacement bulbs to help you compare such factors as efficiency, lifespan, warranty and more.
According to recent reports, the number of Americans buying LED bulbs has doubled in the last two years, to around 66 percent. LEDs are prized for their energy efficiency, brightness and longevity. We have previously covered helpful tips on how to pick the best light bulb to increase energy efficiency for your home, which you can continue to use as a resource.
Ambit Energy hopes the reviews of LED replacement bulbs below will give you a better understanding of the product options available.
Cree’s 60W Replacement LED
  • Price: less than $10
  • Lifespan: 25,000 hours (or 22.8 years based on 3 hours of use per day)
  • Estimated yearly energy cost: $1.32 (based on 3 hrs. per day, 11 kWh)
  • Warranty: 10 years
  • Lumens per watt (efficiency): 79
  • Cree’s original LED bulb remains a popular choice since its debut in 2013. CNET has praised the bulb for its satisfactory performance, superior efficiency and warranty. Overall, this bulb packs much value at an affordable price.
Philips 60W Replacement Bulb
  • Price: $5
  • Lifespan: 25,000 hours (or 22.8 years)
  • Estimated yearly energy cost: $1.02 (based on 3 hrs. per day, 11 kWh)
  • Warranty: 3 years
  • Lumens per watt (efficiency): 79
  • This bulb arrived in May 2015 with much fanfare because of its low cost. Consumers can purchase the bulb for as little as $5 at major home improvement stores. CNET noted its exceptional efficiency and excellent light quality. The only downsides are that the LED bulb isn’t dimmable and its lifespan isn’t as long as its competitors.
GE BrightStik
  • Price: $10 for a three-pack
  • Lifespan: 15,000 hours (or 13.7 years based on 3 hours of use per day)

  • Warranty: 5 years
  • Lumens per watt (efficiency): 79
  • This budget-friendly LED is excellent for standard household lighting. But the bulb isn’t as bright as other LEDs. The product’s five-year warranty is “one of the best you’ll find at this price point,” according to CNET.
EcoSmart 13-Watt (60W) LED A19
  • Price:  $25
  • Lifespan: 25,000 hours (about 23 years)
  • Lumens per watt (efficiency): 71
  • Estimated yearly energy cost: $1.57 (based on 3 hrs/day, 11/kWh.)
  • Warranty: 5 years
  • Good Housekeeping praised the EcoSmart product, noting that consumers enjoyed its brightness and how it cast light evenly. The bulb can replace an A19 or 60-watt bulb. The EcoSmart bulb is dimmable, which can help conserve energy over its lifespan.

Students use solar power to continue gardening projects


Students use solar power to continue gardening projects


Students use solar power to continue gardening projectsFall time may be here, and while many gardeners are hanging up their their sheers and spades, middle school students at Ellis School are just now planting a crop of lettuce seeds that, thanks to solar energy, will be harvested in the dead of winter, the Union Leader reports.
According to the news source, the school's educational greenhouse program will soon use a solar hot water system to keep the plants warm throughout the frigid New Hampshire winter. The program, which began last year, has been helped by a host of volunteers and generous contributions, including a $5,00 grant from Lowe's "Toolbox for Education" fund program.
"There are so many different lessons this can give to the students," said Jen Rydeen, vice president of the school’s Parent-Teacher Association.
The school sought the help of the Seacoast Area Renewable Energy Initiative to install the solar system, and also recruited skilled and knowledgeable volunteers to help with the process, the media outlet stated.
New Hampshire and the Northeast as a whole are reporting more widespread use of solar technologies, which has been attributed to the many rebate and incentive programs that are available in several states, including Maine and Connecticut.
