AI Hydra HD 26 or 52

[damon.strange.5]

Hello,
I'm looking to change lights and think I narrowed it down to the AI's. My question is my tank is 30x25x24 so what is my best option? The light would be mounted inside a standard canopy so the would hang roughly 6" above the waters surface. Thanks for looking and helping me figure this out.
I tried to post under the sponsor forum but was unable to.

Depends on what you want to grow.
