My water surface is approx 13x13in

I have been using a 23w cfl in a 8.5in dome clamp light to very good effect , but it seems the plants are growing inward to reach the highest light directly under the 8.5in "spot light"...

Will a 10.5 inch fixture just extend the lighting footprint or does it alter the available par values enough to warrant raising the light?
