What green light does

green light a/s is a Danish specialist lighting consultancy founded in 1994 in Middelfart, Denmark (CVR 17904639), selling LED lighting solutions and intelligent lighting control systems to industrial enterprises, corporate offices, and Danish municipalities. The company began by importing fluorescent tubes and has evolved into a full-service lighting partner that manages projects from needs analysis and photometric simulation (DS/EN 12464-1 compliant) through to commissioning and post-installation review.

Its core technology portfolio spans LED luminaires for industrial, office, public-sector, outdoor, ATEX, emergency, and cleanroom applications, layered with intelligent lighting control add-ons including DALI-2 / D4i (IEC 62386, IoT-ready with per-fixture energy reporting), DALI+ over Thread/Wi-Fi/Ethernet, Casambi (Bluetooth Mesh), MasterConnect EasyAir (wireless with app control), SmartScan (cloud-monitored wireless), and Human Centric Lighting / Tunable White (2700K–6500K). The Retrokit offering rebuilds existing luminaires with new LED components rather than replacing them, and an in-house energy calculation methodology uses temporary measurement devices to quantify pre/post savings. The company also offers proprietary IES/LDT-format DIALux-compatible photometric planning.

The business model is a consultative enterprise sale: pricing is project-based and quote-only with no public list, consultancy is billed at hourly rates, and payment terms are 14-day net cash. Green light sells directly with named account managers (Jakob Skalshøi, Anders Løwe Hansen) and technical consultants, operating from its Middelfart headquarters and a German sales branch in Flensburg. Revenue mix is split across enterprise industrials, commercial offices, and public-sector tenders, with public-sector work emphasizing open standards (DALI-2) for supplier independence. The company is privately held, appears founder/management-owned, has no disclosed funding rounds, and employs 14+ staff.
