Listings include both LED and incandescent bulbs; some products use integrated LED styles (fixed LED modules) rather than replaceable bulbs.
You’ll find both battery-powered and corded mains options. For example, some pumpkin-themed novelty sets run on 3 AA batteries, while many mini light strands plug into standard household outlets.
There are indoor-only strands, outdoor-rated sets, and many labeled for both indoor and outdoor use (including UL-listed options). Always check the product listing or label to confirm the intended use.
Spacing varies by style: dense mini strands often have bulbs about 2–4 inches apart, while novelty or decorative bulbs may be spaced much wider (around 12 inches or more).
Common options include steady (constant) light. Some battery-powered pumpkin or novelty strings also offer a flashing/blinking mode controlled by a switch on the battery box.
