Confirm the actual length and intended exposure limits before buying. The title says two packs, but the included-components field names only string lights without confirming the quantity.

## A good fit for

- Anyone needing a confirmed two-string package quantity before purchase.

## Customer feedback

Only aggregate ratings are supplied, with most ratings in the five-star category but a smaller spread across lower categories. This suggests generally favourable overall scoring alongside some less positive experiences, but the ratings do not identify what customers liked or disliked. They cannot confirm the listed length, pack quantity or waterproof performance.

## Frequently asked questions

### How many lights are listed?
The listing specifies 120 LED light sources. Its title describes a two-pack, but the included-components entry does not confirm the number of strings.
### What is the stated length?
The title states 12 m/40 ft. A feature instead describes 40 ft of lights plus a 3 ft lead, or 43 ft total, so the overall length is not consistent across the listing.
### Can these lights be used outdoors?
The details field says indoor usage, while a feature claims IP65 waterproofing and outdoor use. Clarify the intended exposure limits before using them outside.
### What powers the lights?
They are listed as corded electric and the feature says they connect to USB interfaces, mobile power supplies or computers. A suitable USB power source is needed.
