Richland, in cooperation with European partner GrowLightTech, has completed a top lighting retrofit at the Getliņi EKO greenhouse complex in Latvia. The project involved upgrading the existing LED lighting system with new top lighting fixtures. The installation focused on improving light distribution across the growing area, simplifying installation, and maintaining compatibility with existing greenhouse control systems.

Getliņi EKO was among the first greenhouse complexes in Europe to operate fully with LED lighting. After several years of operation, parts of the existing system began to show reliability issues as they approached the end of their service life. In the summer of 2025, pilot luminaires from Richland were installed in the greenhouse and operated during one winter season to evaluate performance and reliability.
Following a comparison with three other lighting systems, Richland's GLPG (G3) fixtures were selected. The evaluation considered light distribution and return on investment. During the summer of 2025, technical designers and agronomists finalized customized 400 W and 200 W configurations to match the requirements of the greenhouse.
According to simulation and on-site measurements, the installed system achieved more than 97% light uniformity across the crop canopy. The fixture dimensions were aligned with the greenhouse C-profile to reduce structural shadowing and allow integration without blocking natural light.
"Many solutions take a bulkier approach, while we focused on a linear design," said Andy Zhang, President of Richland. "We understand how shadowing affects greenhouse performance, so reducing additional shadows was a key priority in this project."

Each fixture has a standard length of 2.4 meters, with two units covering a five-meter greenhouse span. The driver has a C-shaped design that sits on the greenhouse C-profile, allowing installation without additional mounting structures. According to the project partners, this approach reduced installation time and costs by around 30%.
"We initially planned to install about 50 lights per day, but ended up reaching 78 units daily, including removal of the existing LED fixtures," said Sergey Ogloblins of GrowLightTech Ltd..
After installation, the system was commissioned in one day by grow consultant Andris Stuks of Synergy Solutions. The lighting system operates with a standalone dimming system and is integrated with the existing Sercom climate control platform. This allowed the greenhouse to update its lighting infrastructure while continuing to use its existing control system.
According to Getliņi EKO, the completed project met operational requirements related to lighting performance, installation process and system stability, while maintaining a fully LED-based lighting setup.
