How do I adjust the height safely?

Most pieces rely on a side thumbscrew or internal friction collar that holds the sliding brass tube in position. Support the upper section with one hand while loosening the fastener to prevent sudden drops. Ensure the lamp is unplugged or balanced securely before altering the height, particularly if the fitting carries a heavy glass shade or historic oil reservoir.

Were these originally oil lamps?

A large proportion of Victorian and Edwardian standards started as oil-burning lamps featuring brass fonts and burners at the summit. These were subsequently wired for electricity as households modernised during the twentieth century. Traces of the original conversion, such as burner galleries or threaded collars, remain visible on many surviving examples without detracting from their character.

How do I date an adjustable standard lamp?

Stylistic details such as Corinthian capitals, wrought iron tripod legs, or sinuous Art Nouveau cast bases provide the primary chronological clues. Victorian examples often display heavier classical casting, while Edwardian and 1920s pieces lean towards slender columns and Arts and Crafts simplicity. Patination on the brass surface and the specific engineering of the telescopic joints also help establish the manufacturing period.

Can I use modern lamp shades on them?

Standard fitter rings on contemporary shades can usually be adapted to fit historical brass galleries using appropriate reducer rings or shade carriers. Pay attention to the proportion between the height of the tall brass stand and the diameter of the shade. Silk, fabric, and glass shades replicate the original materials recorded across the period inventory, maintaining the intended visual balance.
