How much can I save by changing out my lighting?
Both businesses and homeowners can save with efficient lighting!
An ENERGY STAR qualified bulb can save about $30 or more in electricity costs over its lifetime. The average home has about 45 light bulbs in approximately 30 fixtures. Assuming your house has 45 light bulbs, you could save about $1,350 in electricity costs over the lifetime of the bulbs. Plus, ENERGY STAR qualified bulbs and fixtures produce about 75% less heat, so they’re safer to operate and can help cut energy costs associated with home cooling.
If you own a business and change out your lighting to a high-performance T8 (HPT8) system you’ll save 20 percent more energy than a standard T8 and up to 40 percent more than T12 systems. These systems also:
- Produce the same total light output as standard T8s, but with better quality light that uses less energy.
- Generate more lumens per watt than T12 or standard T8 systems, which means more light is produced while less energy is used.
- Maintain their light output longer than T12 lamps.
- Enjoy extended life, typically rated to last at least 24,000 hours - 4,000 hours longer than standard T8 or T12 lamps. That’s about two years in a normal office setting!
- Provide better quality light than T12 lamps. HPT8 lamps must have a minimum color rendering index (CRI) of 82 to qualify as high-performance while T12 lamps have a typical CRI of only 60. (CRI is rated on a scale of 1 to 100.)
