It's important to remember that electrical does not just apply to lighting. Electrical is a key component for outdoor kitchens, hot tubs, and more.

Outdoor lights: Installation for low voltage lighting averages about $300/light and another $500 to $1K for the transformer and may require permitting.

Outdoor kitchens may require electrical for elements such as refrigerators and 120v lighting. These typically both require permitting and installation by an electrician and can typically cost a minimum of $1.5k.

Spas/Hot tubs will typically require a dedicated circuit on the electrical panel. Much like outdoor kitchens, these usually require permitting and installation by an electrician and can typically cost a minimum of $1.5k.
