Socket counts vary across listings; the examples show fixtures with 1, 3, and 4 sockets — so these fixtures typically have between 1 and 4 bulbs.
Some brass-finish lights are hardwired and require electrical installation, while others are cordless: rechargeable or battery-powered options that do not need hardwiring.
The product details list metal bodies made of steel and iron.
Most hardwired fixtures use a standard Edison medium (E26) base. Listed maximum wattages for hardwired fixtures include 60W and 100W; some integrated or rechargeable lamps list much lower integrated LED wattages (2W).
Brass-finish fixtures commonly pair metal bodies with glass shades (seeded or clear, jar/cylinder styles). Some use metal shades or fabric (polyester/cotton) pleated shades; mentioned shapes include cylinders/jars and cones.
Warranty information in the listings includes a 3 Year Limited Warranty for several hardwired fixtures and a 1 Year Limited Warranty for at least one brass-finish wall sconce.
