Helsinki Rolls Out Color-Tuning Street Lights

Forty five luminaires – whose color temperature changes from a cool 5000K to warm 3000K – were switched on along a 2 kilometre section of road in the suburb of Kruunuvurenranta this week. If the planned next wave of 1,000 luminaires goes ahead over the next 12 months it’s believed the project will become the largest color-tuning street lighting deployment in the world. The idea behind the installation – which includes a complex dimming regime – is to help alleviate the effects of the long winter nights on the moods of residents. In the early afternoon, the lights are set to a cool 5000K shifting to a warm 3000K in the early evening. In the late evening it becomes cooler – 4000K – and at 11pm it shifts to 5000K for the night. http://luxreview.com/article/2018/09/helsinki-rolls-out-colour-tuning-street-lights
