Though the knowledge that carefully considered lighting is critical to the success of an interior has filtered down from the rarefied world of elite designers to even the Ikea-class, it is still something of secret that a beautiful floor lamp, pendant light or desk lamp can make a room. The work of master of light design Ingo Maurer, whose latest creation is the Johnny B bulb complete with butterflies, or a piece by pioneer of new technology Marcus Tremonto, is the ultimate example of how interesting illumination can transform a space.

The philosophy ranges from light as sculpture (see the delicate Moustache series by Inga Sempe) to light as a discreet answer to functionality (see the clever but practical Piani range by Ronan and Erwan Bouroullec for Flos, which double as shelves or tidy trays). Or even light as a way of adding humour and whimsicality, as seen in the recent trend for lamps that resemble birds (see the work of Ed Carpenter or Atelier Areti).

As ever, some of the most impressive creations can be found in the re-editions of design classics. The iconic Akari lanterns by Isamu Noguchi are enduringly striking and his range of mulberry-paper lighting is so vast that it includes a number of little-recognized gems. Similarly, the cult-status fixtures by Poul Henningsen for Louis Poulsen are as contemporary as they were in the 1980s and are now available in a new palette of colours, including cool mint green. It’s a moment of enlightenment in the design world: a perfectly chosen lamp is the brightest idea for an instant interior update.
