Top 7 Best COB LED Grow Lights – 2020 Reviews

The COB LED Grow Lights have taken the indoor grow light industry by storm. As the latest market trend, they have all but replaced the traditional HID bulbs that are not just bulky but relatively unreliable as well. So what are COB LED grow lights? COB, or chip-on-board, is primarily an LED packaging technology which works by mounting a multitude of LED chips to form a module. For them to function as a single source of light, these multiple miniature LEDs are wired together in a copper or ceramic board. When it is lit, this board looks like a single light, rather than multiple different lights.
