Here is a pair of gravity light bulbs that float on your desk thanks to magnetic levitation. These magnetic levitating light bulbs are pretty simply to use: simply put the base on a flat surface and lower the bulb over them. Once the connection is made, these light bulbs are powered through air.
Magnetic levitating light bulbs are available in a variety of designs. Some of them even have a smartphone wireless charger built into their base. The above video shows two of these gravity defying bulbs.
