Yep! Have stated that before. However, the 5x5 is an odd bird. Simply put, there is no way to get complete even coverage that I've seen other than this light. Even if you can get the side to side even, there's no way to get the front to back. The closest I could find would be 2 mars hydro sp 3000.
Then you have spectrum on top of that...The Tarantula has 2 blue spikes lots of red, UVA, far red, etc...
Have the photontek 1000W and have liked it, but once again, not great for even coverage and spectrum could be much better!
Like the 4x4 bed and I always maximize the 5x5 space and want even coverage
