Thanks Troy, So the bulbs will still work in a regular MH ballast? Will using a regular MH shorten the life of the bulb? The reason I ask is because there is a guy up in surrey, who says that he can do the whole setup for under 100.00. But he wants me to get a bulb first ,so that he can make sure the ballast will work? I just didn't want to be limited to that bulb, seeing a how I haven't even setup up my tank yet.
