Well damn. The thing cost me $300. When I bought it, it said 4000w output but “usage” wise is 400w for cheaper electricity bill monthly lol. If I knew this, I would have just bought a true 400w for $40.

400 true watts LED is not a bad light. Should cover a 4' square okay. I have a 5' tent. 640 true watt LED. I use a quantum PAR meter to set light height. At 80% power it was hitting 800+ at the tops. I got a lot of weight. The bar type arrays are better for the lower wattage lights.

Yeah, there's lots of people out there that are growing with less light. At 4x4 (16 square feet) you're getting 25w per square foot. In a 5x5 it's more like 16w.
