This Costco seasonal offering includes three sets of commercial-grade twinkle light strings, with 150 lights per set for a total of 450 lights. Commercial-grade construction means heavier-duty wiring and bulb sockets compared to standard consumer light strings, making these suitable for extended use and repeated seasons.

Each string features classic twinkle-style mini lights that produce a sparkling, flickering effect ideal for decorating Christmas trees, mantels, staircase railings, wreaths, or outdoor shrubs. The multi-set bundle provides generous coverage for larger trees or layered decorating across multiple spaces.

These light strings are designed to connect end-to-end for extended runs and are intended for both indoor and outdoor seasonal display. The commercial-grade rating indicates compliance with higher durability and safety standards than typical retail holiday lights.
