white strand christmas lights

These strands commonly come with clear, white, or green cords, so white lights may be mounted on any of those cord colors depending on the set.

You’ll find plug-in electric strings, USB-powered sets, and battery-operated models (some battery sets use 3 AA batteries).

Several sets are listed as UL certified or UL listed for indoor and/or outdoor use; UL is mentioned in multiple product details. Verify each product’s certification on its listing.

Several sets include clips—either one at each bulb base or separate mounting clips—to secure strands to rooflines, gutters, fences, or foliage. Curtain-style sets may include special mounting clips.

Product details state that LED holiday lights can use up to 90% less energy than traditional incandescent bulbs; that comparison appears across multiple LED set descriptions.
