Aranet & Ledgnd Partner on Real-Time Light Insights

Aranet, a leader in wireless sensor ecosystems for the horticulture market, and Ledgnd, an expert in the optimal utilization of lighting technology, have jointly developed a new solution designed to help greenhouse growers optimize lighting strategies based on real-time spectrum data.

The integrated solution combines the newly launched Aranet Light Spectrum sensor with Ledgnd’s lighting control intelligence software, enabling precise monitoring and dynamic adjustment of light intensity and color composition. This integration helps growers improve crop quality and yield, extend LED fixture lifespan, and reduce energy consumption—key benefits in today’s sustainability-driven horticulture industry.

Light Spectrum sensor scheme
Aranet, a brand of SAF Tehnika, is launching the Aranet Light Spectrum sensor at GreenTech Amsterdam 2025. The device delivers real-time spectral data across the 350 to 950 nanometer range and provides significantly broader analysis than standard PAR sensors. Aranet Light Spectrum sensor measurement data can be accessed via Aranet Cloud for light intensity and light spectrum insights.

At the same event, Ledgnd is unveiling the integration of the Aranet Light Spectrum sensor into its MyLedgnd platform, offering growers intuitive data visualization and control capabilities. This seamless integration allows users to optimize their lighting strategies based on detailed insights into both light intensity and color spectrum.

Research has shown that each crop requires its own unique light color mix. With this sensor, growers gain insight into the actual light their crops are receiving. Using the data from the sensor and the further processing within the MyLedgnd platform, growers can fine-tune their lighting strategy.

With rising energy prices and a growing drive for sustainability, more growers are switching to LED lighting. While this transition requires an initial investment, it also results in significant energy savings. However, simply installing LED lights is not enough to achieve optimal results, says Maarten van Bemmel of Ledgnd, who is Product Owner of the MyLedgnd software portal.

“MyLedgnd offers growers a practical and user-friendly way to visualize their greenhouse data. It provides a clear picture of different climate factors and their impact on crops, enabling growers to optimize their cultivation strategy accordingly.”

A Better Light Mix
To gain the right insights, data is essential. And to collect data, sensors are needed. Until now, most growers have relied on PAR sensors, which only measure the 400–700 nm range. The Aranet Light Spectrum sensor, developed in close collaboration between both companies, offers significantly broader coverage and breaks down the amount of light per color in real time.Studies suggest that crops develop better when provided with a targeted light spectrum.

“A better mix of light results in improved crop growth, higher yields, and better quality,” says Gints Antoms, Global Business Development Director at Aranet. ”Our newly developed sensor provides insight into exactly how much light of each color reaches the plant, empowering growers to fine-tune their lighting strategies with precision.”

Improved productivity isn’t the only advantage. Growers can also dim lighting more precisely throughout the day to save energy. Additionally, they can extend the lifespan of their LED fixtures, as certain color chips last longer than others. By managing this actively, the lifespan of the lighting system can be extended.

Wireless and Real-Time
The Aranet sensor takes measurements at intervals of up to every minute and sends data to the base station using long-range wireless technology. The data can be analyzed via Aranet Cloud and can also be directly used by MyLedgnd and/or the climate computer. Combined with plant feedback sensors, MyLedgnd offers a complete picture of how crops respond to light and climate conditions.

Moreover, the new sensor is affordably priced, making it accessible to many more growers. Sensor battery life is up to several years, and it can be placed anywhere in the greenhouse for optimal measurements.

Anyone interested in the Aranet Light Spectrum sensor can visit the Ledgnd (02.231) or Aranet booth (01.625) during GreenTech Amsterdam from June 10 to 12 for a live demonstration.
