Scientists have already developed a series of plant-gardening lighting technologies. LED grow lamp is one of these technologies, which is usually compared with traditional HPS (high-pressure sodium lights). LED grow lights combined red rays and blue rays. Normally, they will be settled on the ground, or places near plants. What are the differences between LED grow lighting products and HPS? What advantages that LED grow lights have?
1) Plants under the LED-light will grow faster. Various data shows that LED grow lamp is a superior technology, which make plants grow better and faster. The Department of Horticultural Science of the University of Minnesota has recently published a related study report of plant lighting. In this study, LED grow lights and LED Panel Light HPS have been comprehensively compared in different conditions. They compared plants (after 7 weeks) from two different local plant bases using these two kinds of lamp relatively and found out that, the average growing speed of LED-used plants will be higher than that of HPS-used plants. The difference is noticeable.
2) LED costs less. Indeed, the initial production cost of LED lamps is usually higher than that of HPS lighting sources. But if take the operation cost into account, high-quality LED grow lamps can save more money in this part. With the same output luminous flux, high-quality LED grow lights consume only 1/8 of energy that HPS needed, and more durable than HPS. Usually, grow lights should work in 24 hours. In the long term view, the initial cost of LED light sources can be ignored.
3) LED grow lamps are lighter. Traditional grow lighting sources are relatively heavy, since HID, MH and HPS need ballasts to maintain a normal working condition; reflectors to concentrate light towards plant pools; other assisted tools or equipments. Gardening lamps usually need to hang on certain places, like the close top of plants. The weight is a must-be-considered factor. Some high-quality LED grow lights have embedded ventilators, negating the need of air-cooled reflector or pipelines.
LED grow lamps make things much easier, generating sufficient red and blue rays that needed by plants, intelligent self-control system and manual adjusting system, saving more maintenance and replacement cost for users.
