Energy efficient lightbulbs
Compared to traditional incandescent bulbs, energy-efficient lightbulbs such as halogen incandescent, compact fluorescent lamps (CFLs), and light emitting diodes (LEDs) typically can last 3-25 times longer and use about 25%-80% less energy than traditional incandescent, saving you money.
As part of the SAVE project trial participants were offered different marketing strategies to test how these effected uptakes of energy efficiency. These included discounted LED bulbs and also LED bulbs installed at zero cost to the participants, each tested across two distinct trial periods.
