Salt River Project (SRP) is giving away a half-dozen compact fluorescent light bulbs (CFLs) at no cost to customers to help them start the year saving energy and money.

To participate, SRP customers need to go to savewithsrp.com and complete an online form. SRP will then mail customers two A-shaped, two globe and two T2, or “spiral” bulbs at no charge. Supplies are limited and given on a first-come, first-served basis. Delivery will take up to 8 weeks.

ENERGY STAR qualified CFLs use up to 75 percent less energy and last up to 10 times longer than standard incandescent bulbs. Customers can save energy immediately by installing the free CFLs in lamps and fixtures they use most. The living room, bedrooms, ceiling fans and bathrooms are ideal spots to start. Lighting accounts for about 10 percent of energy use in Valley homes, and CFLs save about $30 or more in electricity costs over each bulb’s lifetime.

In addition to the giveaway, SRP offers customers discounted prices for energy-efficient lighting at retailers throughout the Valley. Visit savewithsrp.com to find participating retailers, or when shopping for lighting, look for SRP signage that indicates an immediate discount.

According to ENERGY STAR, if every home in America replaced one incandescent light bulb with an ENERGY STAR qualified CFL, in one year, enough energy would be saved to light more than 3 million homes.
