For generations, farmers have relied on the dependable sun to nurture their crops. They’ve meticulously planned planting seasons, hoping for ideal weather conditions, and utilised techniques like crop rotation to maintain soil health.
However, with the rise of controlled-environment agriculture (CEA), including greenhouses and vertical farms, growers are turning to a new kind of light source: LEDs. This shift is more than just swapping out bulbs; it’s a complete transformation of how we cultivate.
Traditional High-Pressure Sodium (HPS) lights and even fluorescent lights, in some cases, have long been the workhorse of indoor agriculture. They provide adequate light but come with significant drawbacks. HPS lamps are notorious for generating excessive heat, requiring complex ventilation systems that drive up energy costs. Additionally, their broad spectrum of light can be wasteful, as plants only utilize specific wavelengths for photosynthesis.
Enter the LED Revolution
LED technology offers a game-changing solution for CEA growers. Unlike HPS lights, LEDs are highly energy-efficient, converting most of their input power into light with minimal heat generation. Using LED light fixtures translates to significant cost savings on electricity bills. But the true magic lies in the wavelength specificity of LEDs.
Tailoring Light to Specific Needs
LED luminaires, like Valoya’s innovative RX Series with Solray 385FR spectrum, allow growers to achieve better quality and higher crop yields with a tailored light recipe for their specific crops. This is a far cry from the one-size-fits-all approach of HPS lamps. For instance, the Solray 385FR incorporates far-red light, which has been scientifically proven to enhance both flowering and stem growth.
This is crucial for high-wire crops like tomatoes and cucumbers, where strong stems are essential for supporting heavy fruit.
Valoya’s Recipe for Success
With years of extensive research and diverse trials, LED grow light manufacturers like Valoya have been developing high-quality horticulture lights to help cultivators get better yields from their crop production practices. Valoya’s Solray 385FR spectrum provides a white-appearing light, ensuring excellent visibility for growers within their CEA facilities. This seemingly simple benefit translates to improved plant monitoring and overall production efficiency. Furthermore, the Solray 385FR spectrum helps in robust and resilient plant growth.
Beyond Efficiency: Enhanced Quality and Shelf Life
The impact of LED lighting goes beyond just cost savings. Studies have shown that specific LED light spectrums can influence the quality and shelf life of fruits and vegetables. The Solray 385FR, for example, promotes higher sugar content, leading to sweeter-tasting produce.
This not only improves consumer satisfaction but can also command premium prices in the market. Additionally, the tailored light spectrum contributes to a longer shelf life, reducing spoilage and waste within the supply chain.
Seamless Integration for Existing Systems
The good news for growers already invested in HPS lighting systems is that the transition to LEDs can be surprisingly smooth. Valoya’s LED light fixtures, like the RF Series, are designed for 1:1 replacement of traditional fixtures.

For instance, the RX325 can seamlessly replace 400W or 600W HPS lamps while offering significant advantages. Growers can expect electricity savings of up to 50% while maintaining a light output of up to 880 μmol/s for their crops. Similarly, the RX600 offers a 1:1 replacement for 1000W HPS lamps, again delivering substantial energy savings and light output up to 1700 μmol/s.
The Future is Bright with LEDs
The shift towards LED lighting in CEA represents a significant leap forward in crop production practices. From substantial energy savings to enhanced crop quality and extended shelf life, LEDs offer a compelling value proposition for growers.
With continued research and innovation in LED technology by grow light manufacturers like Valoya, we can expect even more exciting developments in the future, paving the way for a more sustainable and productive agricultural landscape with more advanced LED grow lights for plants.
