I’ve used many different types of lights, none can match this Spider 4000 dimmable, my plants are growing right out of their shorts!!!!
Its an impressive light to say the least. Easily hits 4x4 footprint. 5x5 is a bit of a stretch. I don't use a tent but where this hangs I was able to remove 4 other single board 150w lights from another brand. So a lot less heat! Less running the AC! All around great investment. You can't go wrong with Spider Farmer.
Love this grow light glad I bought it best bang for your buck
