How do I identify a 1920s desk lamp?

Look for heavy cast brass construction, adjustable flexible arms, and specific switch mechanisms characteristic of early electrical fittings. Many examples also incorporate period styling cues such as stepped Art Deco bases or utilitarian workshop designs.

Are these lamps safe to use today?

Most surviving examples require professional rewiring and safety testing to meet contemporary electrical standards before daily domestic use. Original brass components and metal holders can typically be retained while updating the internal wiring safely.

Did these lamps originally have shades?

Some pieces retain original fabric or opaline glass shades, while others survive simply as bases ready for pairing. Shade styles range from simple conical metal reflectors to decorative pleated fabric covers.
