Some 1000-watt lights emit less watts than others because they use less powerful LED chips. Of all the lights on this list, the one whose power output is closer to 1000 watts is the Advanced LED Lights XML 650, but its price per watt is the highest. But we believe the coverage it offers justifies its price. The light can illuminate 24 plants to maturity and provides enough coverage for a 5.5ft x5.5ft grow tent. The two lights with the lowest price per watt are the HIGROW 1000W Double Chips Grow Light and the Dimgogo LZ090-XW 1000W Grow Light. However, when it comes to watts produced, the HIGROW light beats its counterpart.
