indoor edison string lights

Spacing varies by set. Common listed spacings include roughly 10 inches, 12 inches, about 2 feet (24.62 inches), and up to 3 feet (36 inches) between bulbs.

Listings typically show explicit ratings such as “Indoor/Outdoor” or “Sheltered Outdoor.” Look for safety/listing marks or notes like UL-listed or ETL Listed, and wording about permanent indoor/outdoor installation, weatherproof construction, or similar protective features.

Common installation features include keyhole slots or hanging loops above each bulb, clips on each bulb base for surface attachment, and simple plug‑in designs. Listings also provide cord lead and tail lengths to help plan placement and power access.

Both options appear in listings. Some strands note replaceable or screw‑in bulbs and may even include spare bulbs; other listings describe integrated “lifetime” LED bulbs that are not intended to be replaced.

Listings show per‑bulb wattages (for example 1W or 2W per bulb), per‑strand examples such as 15 W/strand, and strand or set totals like 70 watts. They also list voltage and current figures (for example 120 V and about 0.58 A) and sometimes maximum connected load values (for example 432 W and 3.6 A).

Options shown include shatterproof or impact‑resistant acrylic bulbs, metal cage shades that protect bulbs, heavy‑duty cords, and generally robust construction noted for improved durability.

Many strands include end‑to‑end connectors. Example listings show linking up to 28 strands end‑to‑end, linkable lengths up to 750 feet, and general “connects end to end” capability on multiple strands.
