Decorative Light Strings

Last Updated: 06/29/18

A string of lamps that operates on AC power in North America (120 V RMS AC, 60 Hz) or via a power adapter or controller that connects directly to AC power, and is used for decorative, residential lighting purposes. The lamps may be replaceable or sealed into the lamp holder/wiring harness.

Life Cycle Cost Savings

For most applications, Energy Star-qualified decorative light strings have the lowest life-cycle cost. An efficient product is cost effective when the energy costs saved over the life of the product exceed the additional upfront cost (if any) of the more efficient model. Energy Star considers both upfront costs and lifetime energy cost savings when setting required efficiency levels. Federal purchasers can assume that Energy Star-qualified products are life-cycle cost effective.
