Lighting Dilemma

[Tony F]

Hi All! I recently moved my reef from a 24x24 14D tank to a Lifegard Aquatics 22 Gallon Long 45° Degree Low Iron Ultra Clear Bookshelf Aquarium - 35.82" x 11.81 x 11.81. Originally I had one Kessil A360WE on the old setup which worked very well. I centered the A360 on the new tank and it doesn't give good even coverage over the entire tank. My ultimate goal is to fill the reef to the max with mixed corals
My thoughts (options) (1) find a used A360 to match what I've got. It's a discontinued light so buying new is not an option. (2) Buying two new A360x -or- (3) buying two (or three) A160X's.
I'm leaning towards the A160 option because of the price differential, but concerned if the 40 watt option is enough. The tank is only 12" deep but I don't know if the 160's will have the penetration required. Would three 160's be overkill?
I've also looked at the AP9, but would rather stick to the multiple single light options as it gives more future flexibility.

OK, I've rambled long enough.... Your thought and suggestions are highly requested. Thanks, Tony

What about a different lens adapter to widen the angle? Is that an option?

I would do either two of the a360 style lights, 3 160s, or put a 160 on each side of your existing light.

"160 on each side of your existing light" Great idea, Didn't think of that. Leaves me with many future options at the least cost. My rock is split with a open space in the center, so that would put the 40W 160's over the rock (least depth to penetrate) and the 90W a360 in the deeper area.
Would I be able to sinc all three with one controller or would I need two controllers?
