They come in both formats: battery-powered sets (commonly using 3×AA or 3×AAA batteries) and corded/plug-in electric sets. Product listings usually state either “battery” operation or list the power source as “electric.”
Lengths typically range from short mini strings of about 7 feet up to longer strands around 33 feet. Bulb counts commonly range from roughly 20 bulbs up to about 100 bulbs, depending on string length and spacing.
Common mounting options include suction cups or hanging holes for windows and flat surfaces, S-hooks and U-stakes for hanging or ground displays, and simple plug-in setups for corded decorations.
Some sets include replacement bulbs and spare fuses, and a few mention features like a Lamp Lock that keeps bulbs replaceable and secure. Check the product details to confirm which spare parts are included.
Battery-powered pumpkin strings are portable and usually controlled by a switch on the battery box, offering modes like steady-on and flashing. Corded sets plug into power and often provide more light functions and built-in timers (for example, an 8-function set with a 6-hour-on/18-hour-off timer).
