The real light of the water: (1), paragraphs 1, 3, 5, 7 semi-bright lights, the rest of the bright. (2) a bright 1/8, 2 bright 2/8, 3 bright 3/8, 4 bright 4/8, 5 bright 5/8, 6 bright 6/8 7 bright 7/8, 8 full-bright. (3) to a little difficult, all the lights gradually from dark to full brightness, and then from full bright to dark. (4) the hardest: 8 light from the first start in turn gradually brighter, until the last one. From the last one from the dark, until the first. So on ad infinitum. This is true of light water.
