Choosing Christmas Lights That Draw Little Power
Start with LED sets
Every pick here uses LEDs. Check the light source in the specs when you shop other sets, since some still use incandescent bulbs.
Let the sun or batteries do the work
Solar sets charge in daylight and need no outlet. Most battery sets here run on AA or AAA cells, so plan to keep spares on hand.
Use a timer or dusk to dawn switch
A 6 hours on, 18 hours off timer keeps lights from running all night. Solar sets that switch on at dusk and off at dawn handle it for you.
Turn the brightness down
A dimmer lets you run lights softer on quiet evenings. Look for listed levels or a remote that adjusts brightness.
Only trust listed watt figures
Few listings state watts, and only the FairyGlim 33 ft does among these picks. Compare only what each listing states plainly.
