Every light bulb is designed to fit one of dozens of possible sockets, determined by its base. These sockets can be used to operate bulbs of your choosing, and specialized adapters allow you to utilize a bulb with a different base in existing sockets. Ensure you properly assess your fixture's electrical capacity whenever you work with sockets or adapters.
