I am changing out my MH bulbs for the first time. I swithched brands and went with the XM 20K mogul bulbs. I have screwed them in until they are snug, but it doesn't seem like these bulbs are screwing in as far as the last bulbs. Do the bulbs need to be rotated to a certain position? Does the bulb need to be rotated where the writing is facing downward toward the water? I don't want to over torque the bulb or take the chance of frying three 400 watt MH bulbs.
