What to know before buying

Listing details to confirm

The listing is inconsistent about the number of preset modes: the feature details and main feature copy say 105, while another item highlight says 125. Confirm which mode count applies to the selected listing. The listing also calls the lights waterproof in some copy but specifies IP44 and water resistant elsewhere, so do not treat them as suitable for immersion or unprotected exposure beyond the stated rating.
