Do LED grow lights save electricity?
The Economics Of LED Lighting The results of the economic analysis comparing the costs associated with LED grow lights with the expense of using HPS lighting include the following: For the same crop yield, LED lights cost 75 percent less than HPS lighting . Plants can use only 30 percent of HPS light compared with 50 percent of the light generated by LED systems. In addition, 30 percent of the energy used by HPS lighting is lost as heat. The typical lifespan of an LED light is as long as 19 years, whereas HPS lights need to be replaced every few years. The cost of using LED lights for a 12X12 foot plot is approximately $1,500 per year. The cost of using HPS lighting is a whopping $4,829 annually. Since the operational costs of using LED lights are a mere fraction the expense of running HPS lights, growers report they quickly recoup their investment in LED lighting systems and then realize significant bottom line improvements in their grow opera...
