LED lights are preferred over other and older forms of grow lights because they offer the growers with a better cost to performance ratio. They consume very little electricity and don’t heat up, as well as last for a really long time when compared to older lights. Moreover, LED lights aren’t really dependent upon a single bulb and have multiple diodes in them - which means that even if a couple of them stop working the others won’t really be affected. LED lights are also easy to operate and safer when compared to other grow lights as there are no chemicals involved.
