          Comments about Philips 175 Watt Clear ED28 Mercury Vapor Bulb:

          I use this product for one of my saltwater aquariums. See, I am about to start my own Aquaculture Farming Buisness.

          This light has a color temperature of 6000K and is 375 watts. I am running it along side another aquarium that is 14000K and 150 watts. So it's a bit of a science/business experiment.

          So far, I'd say the mercury vapor bulb is working out quite well and I am looking foreward to noting the differences in my nano-ecosystems.
