MH bulb orientation

[Tom R]

I have read something on having the stack in the glass tube pointing up. This was to get the most efficient use of the bulb. Since then a number of people have just laught when I have suggested that. To compensate for the quarter or half turn required you would have to adjust the mogal. I have pulled the contact point in the base of the mogal out so that the bulb will touch with yet a quarter of a turn to go.
