Spider Farmer SF4000 450W LED Grow Light..
If you want a serious upgrade in coverage and intensity, the Spider Farmer SF4000 is the powerhouse pick. It was the largest, heaviest, and most expensive light we tested, and it produced the broadest footprint with extremely intense light in our basement grow area. For bigger indoor veggie or flower grows, it’s a strong choice, plus you can daisy chain up to 12 lights.
