Lighting to replace 48" ATI Sunpower

[Plainswalker]

I've been using a 6x48" ATI Sunpower for the last 5 years on a 48x18x24 90 gallon mixed reef. Great light, pretty happy with it, but I am just annoyed by the bulb replacements. The tank is slowly rebuilding from a system crash a year or so ago, so I have montipora, LPS (duncan/euphyllia) and an RBTA. I do have my eye on starting to put acros in again at some point.

Would it be sufficient to replace the sunpower with 2x AI Hydra 32s? I figure if I space it at the 1/3 and 2/3 spots across the tank, it would have good light spread, but I don't know if it would be enough.

If I replaced my ATI Sunpower fixtures on either of my tanks, I would go back to Radions.

Plan on replacing those Hydras in about 5 years. Factor this cost against your bulb replacements. Very few people use a LED more than 5 years - there are some, but they are in the minority. Then factor in a third/fourth hydra or some T5s to help with the spread that you are used to getting.
