A major overhaul of street lamps across the city will save millions of pounds and help show Edinburgh in a better light, it has been claimed. Radical plans have been drawn up to replace dull sodium bulbs with bright LEDs as part of a £30 million project to bring the Capital’s street lights into the 21st century. The energy-efficient bulbs will save nearly 40 per cent on the £2.97m spent each year illuminating the city and are likely to offer even future savings with energy prices expected double in the next decade. It is understood lighting inside tenement stairwells – paid by the public purse and costing £800,000 a year – may be given an upgrade as LED bulbs would be installed across 14,000 tenements. The roll-out comes after a successful trial in Saughton Mains and Gilmerton Dykes, where 271 lights were upgraded. The change received an 80 per cent public approval rating. To date, a £2.1m interest-free loan has been secured to transform 6000 street lights, but environment chiefs are targeting a city-wide roll-out ultimately costing around £30m.
