LED grow lights are a relatively new type of grow light which produce better quality buds and bigger yields, while using less electricity and producing less heat than traditional grow lights. LED yields are improving every year and there are now many reliable models of VIVOSUN LEDs that have been proven for growing high yields indoors by various growers in the industry. Unlike a lot of other brands, VIVOSUN LED grow lights have both a heatsink and built-in fans to help keep grow lights cool.
