"Hmm... What about 3 of these across a 4 foot tank instead of 2 xr30? Might be more even spread and slightly cheaper."
That would definitely get you a larger spread and some overlap from the fixtures. As long as you don't have a cross-brace on the tank.
With the wide angle lenses the XR30's reach almost 36" too.
Love the versatility that this new fixture will give to hobbiests - and stores
