Use this calculator to estimate your energy and cost savings associated with using ENERGY STAR lighting fixtures instead of traditional incandescent or halogen lighting fixtures.
Savings are for wattages shown. Your actual savings will vary based on the wattages you purchase. When comparing incandescent or halogen bulbs to ENERGY STAR qualified bulbs or fixtures, compare the light output, or lumens, and not Watts. Watts equal the energy used, not the amount of light.
