LED sphere and globe string lights use several power options: USB power, battery operation (examples show sets requiring 2 AA batteries), and standard mains power from an electrical outlet.
Common string counts include 10-bulb and 20-bulb sets. Decorative ornament collections are often sold by piece count (for example, 61-piece or 120-piece sets) rather than as a bulb-per-string count.
Many globe string lights include end-to-end connectors so you can link multiple sets and built-in clips at each bulb base to simplify hanging and securing the strand.
Listings commonly show G50 and G40 globe bulb shapes. Some ornament-style sets use integrated LEDs built into the decorative spheres rather than replaceable bulbs.
