Turn off those lights!
15 April, 2013 by Mike Smyth, specialist technical writerWhat’s with this fetish for having office blocks lit up like Christmas trees that can be seen from outer space and probably beyond? I suspect it might be fashion. Somebody started lighting up their edifice, first with floodlights from the outside and then from the inside. Not to be outdone, others followed, leading to the beacons we have today.
