PPL Electric Utilities is offering customers who sign up for paperless billing through Dec. 15 one free LED light bulb while supplies last.

Customers will receive their bulb via U.S. mail within 4-6 weeks. Existing paperless billing customers are not eligible.

LEDs help reduce energy costs because they use up to 80 percent less energy than incandescent bulbs and can last up to 20 times longer. The bonus bulb being sent to PPL Electric Utilities customers produces more than 800 lumens of soft white light, about the same as a 60-watt incandescent bulb.
