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.
