Danish designer Poul Henningson's PH 5 pendant lamp is so iconic…

…it's easy to forget that it wasn't a standalone object; it was part of a series incorporating Henningson's very specific arrangement of shades.

"PH did not just design a light, but an entire system – around a thousand different models have been produced over the years," writes manufacturer Louis Poulsen. "This wide selection consisted of table, floor and wall lamps, as well as a number of different chandeliers, which were very popular in the 1930s for lighting private homes from high ceilings. There were countless combination options."

The smallest of the PH series, the PH 2/1 table lamp, has received a modern upgrade that Henningson couldn't have imagined: It's wireless, thanks to a rechargeable battery powering LEDs.

It's one of those products that looks better on video than in stills:

The shades are mouth-blown opal glass, and the bases are available in brass or chrome finishes. The LEDs feature a stepless dimmer. The battery offers a 5.5-hour runtime at 100%, up to 120 hours if dimmed down to 5%. The asking price is $1,043.
