The top of spinning shade lamp is formed in the shape of a turbine. Heating the air in the shade brings a convection current. This convection current moves upward to bring breeze. Then, the shade is propelled.
Check the lamp. Manually spin the attached shade without plugging in the lamp to check to see if the shade spins freely. The shade should rotate without significant friction or obstruction. Remove the finial that secures the shade to the wire harp. Clean the post or bushing on which the lampshade rotates. Sometimes, use silicone or graphite lubricant to reduce friction between moving parts.
Remove the shade, and then screw an incandescent bulb into the lamp’s socket. To get stronger convection current, you had better choose higher-wattage incandescent and fluorescent bulbs as they can bring more heat.
Reassemble the lamp to make sure the shade is plumb. Plug in the lamp and turn it on. The heat generated by the bulb should cause the lampshade to begin rotating momentarily depending on the wattage of the light bulb and the weight of the lampshade. Please turn off the lamp and install a higher-wattage light bulb if the heat is insufficient to turn the shade.
Never exceed the manufacturer’s light-bulb wattage recommendation.
