nobody has mentioned what I consider the biggest difference....
Heat.
Reflectors do just that...for both the light and heat. That's why a horizontal setup (w/o aircooling) must be kept a foot++ away from tops to avoid bleaching/burning...
Vertical setup allows heat to rise up away from lamp/plants to top of room...
I think this more than makes up for any possible difference in lumens/meter stuff....
I've grown both ways...the girls really seem to prefer vert unshielded lamps from my experience.
Either way will produce fine results if other environmentals are good...
