Plessey LEDs support vegetable and flower horticultural lighting applications
announced four horticultural lighting trials in the Netherlands that are using fixtures developed by the company that mix colored LEDs with its phosphor-converted white LEDs based on silicon substrates — generally referred to as gallium-nitride-on-silicon (GaN-on-Si) LEDs. Dutch companies Villa Gerbera, Gebr. Koot BV, Together2Grow, and Slijkerman are respectively testing the solid-state lighting (SSL) on Gerbera (daisy family), tomatoes, Alstroemeria (lily family), and Kalanchoe (a decorative succulent). The trials will run through the summer at which point the effectiveness of the LED lighting will be evaluated.
