LED luminaires for professional plant cultivation

DEMETER

Light tailored to the requirements of a specific crop

DEMETER is a range of LED luminaires for greenhouses, vertical farms, and indoor cultivation. The system allows the light parameters to be adapted to the crop requirements, supporting efficient and modern supplemental plant lighting.

Professional lighting
for greenhouses and vertical farms

DEMETER is a range of LED luminaires designed for professional plant cultivation. The system is used in greenhouses, vertical farms, specialist growing halls, and indoor facilities, where high supplemental lighting efficiency, durability, and the ability to tailor the light to the needs of a specific crop are essential.

Key advantages of the DEMETER system

High efficiency and light control

An efficacy of 3.5 µmol/J supports efficient supplemental lighting for plants in professional cultivation applications.
Tailored spectrum makes it possible to select light parameters according to the crop requirements and the plant growth stage.
Spectrum and brightness control increases system flexibility and allows the lighting to be better matched to the project assumptions.

Convenient installation and maintenance

User satisfaction and safety

Manufactured in Poland and short lead times.
Long service life thanks to high-quality LED diodes and a design that supports optimal power supply cooling.
60-month warranty.
Operation at high ambient temperatures and in demanding conditions. High ingress protection of the luminaire IP65
High-quality components from reputable manufacturers.
Maintaining a constant luminous flux without a stroboscopic effect.
