Put the AHSupply lights and reflectors in a box that covers the top of the tank. The inside of the enclosure can be painted white to reflect light back down into the water. The gaps for fans and vents should allow minimal light to escape -- especially if you mount them around the sides of the cover instead of the top. If you want to make doubly sure of that, then put a louvred screen over the fans or vents.
