Lighting is a category where the market did the buyer a favour by turning over completely. When the industry moved from discharge lamps to LED, decades of accumulated brand advantage reset, and the question became who can engineer thermal management, optics and drivers well rather than who has been making lamps longest. Turkish manufacturers entered that reset with a large domestic market, a deep aluminium extrusion and die-casting base, and a habit of exporting, and a number of them now supply European distributors and contractors directly.
The economics favour proximity more than buyers expect. Luminaires are bulky, fragile and low density: a container of highbays is mostly air and packaging, and damage in transit is a real line item. Two to seven days by road rather than six to eight weeks by sea changes both the freight cost and the risk, and it makes a sample-then-order sequence practical instead of theoretical.
What decides who you can actually buy from is regulation. Under the Ecodesign regulation for light sources, (EU) 2019/2020, and the energy labelling regulation, (EU) 2019/2015, light sources placed on the EU market must meet efficacy and information requirements and be registered in the EPREL database before being placed on the market. Separately, the mercury exemptions that kept fluorescent lamps legal have been expiring: compact fluorescent without integrated ballast and circular T5 ended on 25 February 2023, and linear T5 and T8 on 25 August 2023. That is the single largest retrofit opportunity in the European built environment, and it is what most industrial lighting enquiries are actually about.
