Metal wire star decorations are usually made from metal wires such as copper, iron, and stainless steel; some designs use plated or colored metal finishes (e.g., gold-tone or rose-gold wire). The term “metal wire” covers plain metal, coated, or decorative metal finishes used in these stars.
Lighted metal wire stars use either plug-in (mains) power or battery power. Battery examples listed include 3 AA cells and CR2 lithium cells; remotes sometimes use button-cell batteries such as CR2025. Some products specify either electric or battery power as the source.
Lighted wire stars commonly offer multiple modes such as steady, twinkle, chase/combination, sequential, and fade. Control options often include inline plugs and remote controls, and some models include timers (for example a 6-hour on/18-hour off timer) or a one-click function on the plug.
Some metal wire stars are rated for outdoor or sheltered outdoor use, while others are indoor-only. Look for explicit outdoor wording, weather protection features (examples given include an IP44 waterproof rating or a rain‑tight adaptor) and manufacturer guidance; sheltered outdoor placement is often specified when full outdoor weatherproofing isn’t claimed.
Finishes range from natural metallic wire (copper, rose-gold tones) to glitter-coated styles. Some listings note treated surfaces designed to retain glitter (reduced shedding), while others mention there may be slight glitter fall-off—check the product notes if glitter retention is important.
