LED Technology
The core of Valoya’s technology is a finely balanced wide spectrum optimized through years of testing and through feedback and support of our customers and partners.
The LED market is flooded with companies branding generic LED lamps and trying to pass them off as proper horticultural lighting.
Valoya’s focus since the beginning has been on photobiology research. After testing more than 60 spectra on more than 200 plant varieties / species, we have a solid understanding of what kind of light best serves growers goals.
Our technology is patent protected and industry leading with high µmol/W efficacies (up to 2,4µmol), high IP ratings (up to IP67), a long lifetime of luminaires (50000 hours / down to 70% intensity) and robust and durable design.
LED luminaires do not radiate heat in the direction of light as the generated heat is transferred away from the LED diode to ensure high output and long use life. This means that luminaires can be brought very close to plants, thus enabling e.g. dense multilayer installations. Valoya’s wide spectrum technology provides growers a light that saves energy, increases production and improves the quality of plants e.g. more flowers and better taste. Valoya lights even enable pollinating bees to operate without sunlight.

The Valoya Difference
Artificial light has been an integral part of horticulture for over 30 years and growers are accustomed to High Pressure Sodium (HPS), fluorescent tubes, metal halide and incandescent lights. The artificial light market for horticulture is on the verge of a massive technology disruption, as LEDs are replacing the old technologies.
All Valoya luminaires are tested for durability with burn-in tests whereby we measures the light intensity decay after several thousands of hours of operation. Our luminaires last 50000 hours after which the intensity drops to 70%. After that they are still usable. Most importantly, the light spectrum decays evenly, unlike with most LED manufacturers. This is due to the phosphor coating that we use on the LED chips. Otherwise, it is quite common for shorter wavelengths in the spectrum such as blue to decay earlier, resulting in more stretched plants.
LEDs from several manufacturers are actively cooled with fans or with water and some lack cooling completely (LED fixtures without fans or aluminum heat sinks should be treated with caution). Active cooling is not suitable for horticultural purposes, due to high maintenance. Fans have proven to be unsecure in a greenhouse environment as moisture and dirt gets into the electrical parts (fans) of the product causing hazards. Insufficient cooling or malfunction of active cooling components may result in melting of plastic parts. This could lead to discharge of harmful gases with devastating results on the crops.
