Trial indicates “smart lighting” may save energy, but more data is needed

A recent report from Efficiency Vermont evaluated usage patterns and energy savings of connected LED light-bulbs. The study found that 87 percent of participating households reacted favorably to the bulbs and hours of lighting use went down by 7-27 percent, with additional energy reductions possible through dimming capabilities. However, some caution is in order because of the study’s small sample size. As the report authors state, “these are only preliminary indicators, and more research is needed to statistically guarantee these savings.” Additionally, because the bulbs draw a small constant wattage, they could conceivably consume more overall energy when deployed in seldom-lit corners of the home. Nevertheless, it is encouraging to see data starting to come in from this emerging niche.
