Micro LED string lights are offered as either battery-powered or plug-in (electric) sets. Product listings typically show a battery pack with the required AA battery count for battery models, or list electric/plug-in power for non-battery models.

Micro LED strings range from short craft sizes to strands several hundred inches long. Examples from listings include a 50-bulb, 204‑inch string and 100‑bulb strings around 312 or 411 inches.

Bulb sizes vary but commonly use micro/miniature types (for example 3 mm or T1.75). Spacing typically falls between about 2–6 inches, with some listings specifying exact spacings like 2 inches or 4 inches.

Some listings note safety certifications (for example UL) or weather-related ratings such as an IP44 raintight adapter. Other listed items relate to maintenance rather than certification—examples include lamp-lock mechanisms, replacement bulbs, and spare fuses. Check the product listing to see which safety or maintenance features are included.
