The water cooling is very interesting. There are water-cooled setups for hid lighting, but they are designed to remove heat from a room and require a water reservoir in a separate room in order to have a net cooling effect on the whole room. They are also either a jacket or a coil around the actual bulb and therefore reduce output by making the light pass through extra glass plus water.

Your idea of what I think looks like pex tubing is a very innovative approach to water cooling. It would work for any light, led or hid. The pex makes kind of a reverse radiator that absorbs heat. What size of a water reservoir do you use? Does the water get warm at all?
