Counts vary widely — listings show as few as about 20 bulbs up to several hundred. Example overall-length values from the sample listings range from roughly 8.9 inches up to 1,260 inches. These figures are illustrative; always check the product page for the exact bulb count and total length for a given string.
Some commercial and smart strings support end-to-end connections and device grouping. Sample listings mention connectable end-to-end sockets and connection limits (examples include limits like up to 43 strings or up to 5 sets), while smart systems can sync hundreds to thousands of LEDs across multiple devices. Connection type and maximum connectable sets vary by product, so confirm the product specifications and any power/safety limits before linking multiple strings.
Most strings use LED bulbs. Reported bulb shapes include M5, 5mm, 3mm, and integrated LED bulbs. Listed bulb spacing examples range from about 1 inch up to 6 inches across the sample listings.
Common modes include steady on plus effects such as twinkle, wave, sequential, chase/flash, and slow fade/slow glow. Many plug-in strings list eight preset modes; app-controlled or addressable strings add many more preset and custom animations accessible through their apps.
