because of the sulphur plasma lamps size shape and immense light intensity, it lends itself perfectly to the concept of using a single remotely located lamp to light several different rooms, even on different light cycles without adding ANY surplus heat, by streaming the light via tens of thousands of fibre optic strands to multiple growrooms with a cpu controlling the fibre optic strands individually to cater for each rooms day/night cycle and intensity of light desired for each room and because the fibre optic strands only carry the light and none of the heat, the ends of these strands will be able to touch yr plants without burning at all, unavoidable heat issues for the indoor gardener would be a thing of the past! This concept similar to light piping already used in sp technology is already undergoing research and development...
