How is the MH bulb oriented in the holder?
____ (length of bulb parallel to the front of the tank)
|
| or (length of the bulb parallel to the sides of the tank)
I imagine there is a big difference in spread between the two - dependent on the orientation of the reflector.
The 150 watt units suspended above the Amano tanks in Nigata look like they are pretty high above the water surface - about 18 inches I would think.
