I mount mine horizontal and use LST
Horizontal is better because the majority of the light that coms off a bulb comes off the sides this is true with most cfls and mh/hps systems
A friend of mine recently went from a horizontal 400 watt hps to a 1000 vertical hps. Aside from the need to rotate the plants continuously it seems to use almost all of the light. I think if it works for your space, that would be the way to go.
No I don't have any height limitations really, I do LST to get some "sun" on the lower branches 'cos in nature the sun moves and I don't have a light mover. That being said, The sun is strongest and longest from above than it is at sun rise and sun set so therefore my light is hung above. I do have a couple T8s hung on the side though!

and what about the side of the bulb that is rebounding from the reflector ? this alone loses 40% of its light just doing that , plus with horizontal more heat is aimed toward the plant , sorry i dont agree..........
ok well it all depends on how your room is set up you say that the light bouncing off the reflector wasts lumen's but i think your wrong lets say you have 1 plant
a horizontal reflector at least bounces light back at the plant with a reflector a vertical one doesn't so if there aren't and plants on the other side you get what gets bounced of the walls and more heat is aimed at the plant because more light is aimed at the plant instead of radiating in a 360 degree circle its being focused down
He wanted to make the best use of the lumens available.
Hang horizontal, it reflects light down to your plants if a efficient reflector is used... I have seen vertical setups, you need to be careful when heat spots if hung vertically. Good luck
I just told you.. Horizontal is better, It reflects ALL LIGHT DOWN. If your asking this question you definitely shouldn't even consider hanging your lights vertically.
