## Before you buy

- The waterproof claim applies to the lights, while the listing explicitly says the adapter is not waterproof. Protect the adapter from water. The stated maximum of 69 m for three 20 m strands does not match their combined nominal length, so confirm the total length if it matters. The listing also describes themes as Horror and Space and occasions as Halloween and Thanksgiving despite marketing the product as Christmas lights.

## A good fit for

- Indoor or outdoor seasonal decorating where a mains socket is available.
- Buyers wanting several lighting patterns, a timer, and memory for the previous mode.
- Decorating areas where strands may be connected end to end, subject to the stated connection limit.

## Less suited to

- Locations without access to mains power.
- Set-ups where the power adapter cannot be kept dry.

## Frequently asked questions

### Can these lights be used outdoors?
The listing describes them for indoor and outdoor use and calls the lights waterproof. It also says the adapter is not waterproof, so keep it protected from water.
### How many lighting modes are available?
Eight modes are listed, including steady-on, slow fade, chasing or flashing, and twinkle or flash.
### Can multiple strands be connected?
The listing claims a maximum of three strands, with up to 600 LEDs and a stated maximum length of 69 m. The length figure is inconsistent with three strands listed as 20 m each, so confirm the intended total length.
### How does the timer work?
The timer is described as six hours on and 18 hours off. The listing says to activate it by double-pressing the adapter button until the green lights come on.
