Richland with European partner GrowLightTech has completed the top lighting retrofit at the Getliņi EKO greenhouse complex as part of an upgrade of the existing LED lighting system. The installation was designed to improve light uniformity across the growing area, simplify installation and ensure compatibility with existing greenhouse control systems.
Getliņi EKO was the first full LED greenhouse complex in Europe; its existing LED system had begun to experience reliability issues as it approached the end of its service life. In summer 2025, pilot Richland top light luminaires were installed in the greenhouse and have been running for one full winter season to evaluate their performance and reliability.

Richland's GLPG (G3) came out on top after a head-to-head evaluation against three competing systems, showing strong performance in both ROI and light distribution.
By summer 2025, working with technical designers and agronomists, the team finalized customized 400W and 200W solutions to meet the specific requirements of the greenhouse.

The system achieved light uniformity of more than 97% across the crop canopy, as confirmed by simulation and on-site measurements. A key engineering priority for the GLPG (G3) was to minimize structural shadowing. By aligning the fixture dimensions with the greenhouse C-profile, Richland enabled straightforward integration without obstructing 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."

The fixture has a standard length of 2.4 meters, with two units able to fully cover a 5-meter greenhouse span. The driver features a C-shaped design that sits directly on the greenhouse C-profile, making installation on site more straightforward. This approach helped reduce 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 of GrowLightTech Ltd. "This noticeably sped up the overall installation process."

Following a one-day commissioning by grow consultant Andris Stuks of Synergy Solutions, the system worked smoothly with the standalone dimming system as well as the existing Sercom climate control platform. This allowed Getliņi EKO to upgrade its lighting while keeping its existing control processes in place and avoiding unnecessary additional costs.
According to Getliņi EKO, the completed project met expectations in terms of lighting performance, installation efficiency and operational stability, helping save time and keep overall project costs under control while maintaining a high-quality fully LED-based lighting infrastructure.
