Some patio umbrellas come with lights included or they come setup with a place for lighting should you decide to install lighting later. Choosing the type of patio umbrella lights that will best work for your umbrella is basically up to how much lighting you want and how easy you want the installation to be. Patio lighting should be effective but kept to a minimum if you want the space to be ambient and inviting. Some fixtures are so small they look like stars shining in the sky when you look up at your umbrella. Other fixtures are large enough to be considered spotlights and they shiny way too brightly down at your patio area. String lights for instance, are super easy to install and they come in various sizes so you can choose the amount of illumination you prefer.
