This is a set of two 28W LED light bulbs. Easy installation, just attach them to the light bulb socket. They fit large sockets (E26/27). Just screw them into the socket like a regular light bulb. No tools required. Usable with standard household E26 sockets. 28W daylight white (6500K) LED. The entire fan-like shape, including the center and the blades, emits light. With a long lifespan of approximately 25,000 hours, they use heat-dissipating PC material and are designed to prevent damage from heat buildup. The four blades are foldable. You can adjust the illumination angle by fully extending or partially folding them. For example, fully extend the blades when you want to illuminate directly downwards, and partially fold them when you want to illuminate a wider area of the room. The wider the area illuminated, the softer the light becomes compared to direct light. When using them in a hanging socket, you can fold the blades to emit light. Suitable for use in general households such as living rooms and entrances, as well as garages, storage rooms, warehouses, carports, halls, and stores. □ Specifications Voltage: AC 85-265V, 50-60Hz Current: 500-1000mA Bulb Size: Socket E26 / E27 Luminous Flux: 80lm Daylight White (6000-6500K) The box may be slightly crushed during transportation.
