Cities are moving away from 'brighter is better'. Dark-sky regulations and resident complaints about glare are pushing specifications towards warmer colour temperatures and full cut-off optics.
Adaptive controls — dimming by time, traffic or weather — are becoming standard on new installations. They reduce energy and extend the life of the luminaire.
The aesthetic side matters too: landscape and facade lighting is now part of the identity of a district, not an afterthought. Warm 2700–3000 K light with good colour rendering is the common choice.
For manufacturers, this means more optics options, better shielding and controls integration — and more testing to prove compliance.
