So I'm looking through the instructions for installing a Phoenix 150w HQI bulb, and it mentions positioning the extruding portion of the glass in an "uppermost" direction. This is the first I ever heard of orienting this notch thingy in a specific way. It then goes on to say that the light may not last long and even lose colour. "Uppermost" seems rather relative, and there are no diagrams indicating the appropriate direction. So I was wondering, when it says to make sure that portion is "uppermost", does that mean it should be facing the canopy rather than the water?
