What to know before buying

Listing details to confirm

The listing is inconsistent about color: the title and feature copy say color-changing or multicolor, while the details specify Warm White, confirm the color capabilities of the selected version. IP44 and the listed 29V adapter are manufacturer claims, not independently verified here, the listing also claims the adapter is UL certified.
