I see so many cheap grow lights on the market boasting incredible wattage output, fantastic spectral graphs for such a low price I had to dig into the differences of "cheap" vs "good quality" LED grow lights. As I was doing research I came across this article which perfectly explains why some grow lights are $75 and others cost much higher. This article explains LED chip technology, the myths about wattage claims and much more. This is a MUST read.
As it turns out you do get what you pay for. What seems like a great deal upfront will cost you more in the long run via wasted energy, smaller crop yields and the very real possibility of leaf burn.
