Wow really, it makes a 400w HPS look like a toy?? now even if your LED did have better results i dont think they would be that big of a difference to say 'it makes the 400w HPS look like a toy'.... So how about some pics to back your theory?? And whats your current set up? If what you claim is true than id be crazy to use my HID's instead of LED's, but like i said thats if your claims are true and to no that we will need some evidence and as it sounds like you have a current grow of each lighting system, posting some pics shouldnt be any problem.
I do hope however that your claims are correct cus i would love to give these lights a try.
