I have the Hydra52's, 2 on a 48 L x 30 H x 24 D, and they are plenty strong as evidenced by the pile of BBQ'd SPS I am collecting. I saw something from MACNA that AI is going to come out with a new series called the Hydra HD, which will allow users to overdrive certain LED's....or something like that. I'm not sure the AI's are as popular as the Radions, maybe a superior light.... but someone who has them will have to chime in. I recently added 2 48in. t5 bulbs to my lighting setup, maybe a hybrid LED/t5 setup. I have an Apex and the Hydras are Apex compatible, but I purchased the AI Director (because I didn't have the Apex at the time) so I just run them off of the Director using the AI website for adjustments and setup. It is easy to use and runs the lights very well. Hope that helps a little from the AI side of things! Let me know if you have any more questions.
