It might be too much work now, but what I did was lay plywood on the top of the stand (in your case, under the 50 gallon tank) and screwed hooks into it from which I could hang a light fixture over the bottom tank. But unless you want to drain your 50 gallon now, that won't work. Is there any way you could clamp the light to the back part of the stand rather than the side? Then you could center the light over your 10 gallon tank.
