What to know before buying

Listing details to confirm

The listing is inconsistent about controls, describing button control on the adapter but also listing Touch as the control method. It gives different protection details, including an overall Waterproof claim, IP65 for bulbs and the control box, and IP44 for the adapter. Keep the adapter dry outdoors. The listed 120Vac 60Hz and 31V wording is combined with 6W consumption without clarifying which voltage applies where. The included-components list names lights, an adapter and a manual, while the connectable-light claim mentions male and female plugs without specifying whether additional connection hardware is included. Do not use a timed power outlet if relying on the built-in timer.
