Led grow light 1000W

The first thing is to ignore the really fake advertising numbers. Look at the actual power consumption and that will give you a better idea of the light's capabilities. For a white light I like the power to put out 35 watts per square foot. I use much less power with sprouts and medium power for veg and then crank it up to 30-35 watts/ft for flower. First, I have to say that I have never used any of the lights you mentioned but... All three lights you mentioned are in the same category and appear to be about the same quality. If going by horsepower I'd pick the Spider Farmer since it's 150 watts so you'll get 50% more power for about the same price. If you have a small grow space and 100w is enough I've read good things about Spider Farmer. The Bestva looks wicked cool but I don't like the power supply right above the lights AND enclosed in a cover that hinders cooling.
