I feel the hand method is the best way to go. I'm not there to look at it and I don't want to tell you something that I cannot observe for myself. However as long as the cool tube is being ventilated properly you can get it pretty damned close. I used to own a cool tube with a 400 watt hps bulb and got it less than 6 inches away from the plant tops ventilating with a 265cfm active air exhaust blower.
