Philips Lighting unveiled its new Philips GreenPower LED toplighting with a light spectrum optimized for cut rose cultivation at an event of the Philips Rose Expertise Group. The new GreenPower LED toplighting with cut rose spectrum allows growers to increase light levels year-round without increasing heat. During extensive trials undertaken by research institutes Delphy and Wageningen University, and monitored by experienced rose growers, the new lighting with cut rose spectrum improves the quality of the roses and is 40% more energy efficient compared to high-pressure sodium (HPS) lighting.
