Businesses in Oahu, Maui and Hawaii counties are eligible to receive a rebate of $40 for each incandescent “exit” sign they replace with one that is illuminated with a light-emitting diode, or LED.

The rebates are being offered by Hawaii Energy, the ratepayer-funded energy conservation and efficiency program that operates in the three counties. The offer is available through May 31.

LED exit signs certified by the Energy Star program use about 44 kilowatt hours of electricity a year compared with 350 kilowatt hours a year for an incandescent sign — a savings of 87 percent, according to a news release from Hawaii Energy. For each incandescent exit sign replaced, the savings is about $80 to $100 a year, according to Hawaii Energy.
