DLI ZENITH ECO is a compact LED toplight from Dutch Lighting Innovations designed as a 1-to-1 retrofit for 600W HPS. The fixture uses top-bin Osram LEDs and is offered in 650W or 780W variants, delivering up to 2,700 µmol/s at efficiencies up to 3.55 µmol/J. It is dimmable steplessly from 10% to 100% and operates on 400V. The enclosure is IP65 rated for greenhouse conditions. The body measures 82.5 × 20.7 × 13.3 cm and weighs 6 kg. Built in the Netherlands, the ECO emphasizes stable light output and low degradation over time and carries a 5-year warranty. Its compact form factor and beam-angle options help minimize light interception under climate screens during fast retrofit projects.
