University of Turku scientists in Finland have created a synthetic material based on the natural hackmanite mineral which produces broad spectrum white light in lamps. The hackmanite created by the Inorganic Materials Chemistry research group is a low-cost material emitting luminescence closer to sunlight than that of the currently used lanthanides. The hackmanite developed by […]

Princeton University researchers have built another path forward for LED technologies. By refining the manufacturing of light sources made with crystalline substances known as perovskites, a more efficient and potentially lower-cost alternative to materials used in today’s LEDs can be made. Just as the complexity and bulkiness of CFLs distorted the engineering and lighting market, […]

Researchers at the University of Almería, Spain, determined LED lamps specifically designed for horticultural use were more beneficial to plant growth and had 26 percent higher energy efficiency when compared to conventional LED lamps. Conventional LED lamps are already known to offer better electrical energy efficiency. In horticultural operations, light-emitting diode (LED) lamps are becoming […]

Purdue University researchers have published a study of supplemental lighting experiments in HortScience noting that light-emitting diodes are becoming a viable alternative to high-pressure sodium supplementation. The Purdue team collected physicochemical and sensory data in studies investigating the effect of supplemental light quantity and quality on greenhouse-grown tomatoes. The supplemental intracanopy LED lighting at the […]

Researchers at Aalto University and VTT Technical Research Center of Finland have succeeded in developing a method which helps to improve the relative uncertainty in measuring the luminous efficacy of LEDs. The improvement from the approximate five percent of today to one percent in the future may save billions in lighting costs in the future. […]
