‘There is also an increasing public scepticism of manufacturers’ claims fanned by sensational newspaper headlines on the harmful effects of LED lighting. This is why the industry needs research commissioned by a leading independent professional lighting organisation.’

This falls into the endearing but potentially a bit creepy camp. According to design website Dezeen (www.dezeen.com) Dutch designer Bob de Graaf has created two interactive lights that seek out human companions, either following them around or searching for the darkest spots in the house. Called Species of Illumination they operate through a series of sensors, motors and stretchable cables.

Wallace (as in Alfred) is attached to the ceiling at one end and has three pieces of wire supporting a head at the tip of a long electrical cable. Its

sensors enable it to search out the darkest spot in a room and bring light to it. It then works out where the next darkest point is and moves on to repeat the process.

Darwin is a desk lamp that uses solar power to generate its electricity. During the day it trundles around on wheels looking for sunlight to charge its battery, but in the evening it wanders around the house looking for movement and accompanying people with its beam of light. Ahhh.

Howard Brandston, Hon FCIBSE and FSLL, founded his lighting design consultancy in 1966. Among many honours and accolades, he was given the Illuminating Engineering Society Medal, its highest honour, for his outstanding leadership in the lighting industry, only the fourth designer to be recognised in this way. In 1992 he was included in the Interior Design Hall of Fame, the only lighting designer ever to be awarded the honour. He was the initial inductee of the Lighting Design Hall of Fame and has also received the IALD Lifetime Achievement Award.
