What to know before buying

Listing details to confirm

Listing details conflict: the title and feature text describe a 2-pack of battery-operated lights using 3 AA batteries per string, while the technical power field says "Corded Electric" and the component field lists "String Light" without confirming a two-pack. Length and LED count are described per string in feature text, while the title gives different total figures. Confirm the selected listing's power, pack count, length, and LED count before purchase. IP44 is the stated protection rating, not a claim of unlimited weather exposure.

What’s in the box

String light

Who is it for?

A good fit for

People decorating a Christmas tree, porch, balcony, garden, or other spot where flexible string placement is useful.

Buyers willing to confirm the power source and pack configuration before ordering.

Less suited to

Shoppers who need a confirmed plug-in-only or battery-only product without resolving the listing's power-source conflict.
Buyers who need batteries included or a clearly verified two-string package.

Customer feedback describes the lights as bright and attractive, with positive remarks about the settings, timer, and ease of use. Battery life is mixed, with reports ranging from several weeks to batteries draining quickly. That variability matters if the listed battery-powered configuration is the one supplied, especially for frequent or extended use. The product's stated modes and timer provide context, but they do not establish battery runtime.

Frequently asked questions

Are these lights battery powered or corded?

The feature text says they use 3 AA batteries and that batteries are not included, but the technical details list corded electric power. Confirm the selected listing's configuration before ordering.

How long is each string?

The feature description gives 16 feet of lighted length, a 1-foot lead wire, and 17 feet total. The title's length wording does not match those figures, so verify the package details.

What timer and lighting modes are listed?

The feature text describes eight modes and a timer that runs for 6 hours on, then 18 hours off. The mode is selected with a button on the battery box.

Can the lights be used outdoors?

The listing states indoor and outdoor use and gives an IP44 rating for both the string and battery box. That rating does not establish suitability for every exposure condition.
