Many listings state replacement bulbs and spare fuses are included and note lamp-lock or similar features so bulbs stay secure yet remain replaceable. Several descriptions also specify that the string uses a shunt or lamp-lock design so the rest of the string remains lit if one bulb burns out.

Some LED white-cord sets are described as energy-efficient, with listings noting up to 90% less energy use. Example specifications in the listings include low wattages such as 6.7 watts per string.

Most listings show a white cord. Bulb types vary by product and include LED and incandescent options.

Listings show a variety of bulb shapes, including C6, integrated LED bulbs, G12, C9, 5mm (LED), and M5.

Effects range from steady (constant) to dynamic modes. Listings include options such as twinkling, shimmering/rotating, flashing, fading, chasing, blinking, and multicolor flashing, with some sets offering multiple selectable modes (for example, up to 8 modes).

Wiring materials mentioned include copper (including listings that specify 100% copper wiring). Bulb and string materials listed include plastic or non-glass bulbs, and some listings note glass and metal components for certain bulbs.
