How big a difference do these values really mean? http://www.greners.com/reflector-test.html
The large adjust a wing wasn't as good as the medium, but the adjustability you find handy.
Do you guys use the super spreaders?
Huh I always imagined you with a Mohawk homie!
The other problem with vertical is you can't see anything after spending any time in the room with the lights on.
I agree with Frank...I'm a HUGE Adjust-A-Wing fan!! I run the medium with a 600w HPS. You can adjust it tight for max penetration, or run it in the more flat position for larger footprint. I find I can cover a full 5'x4' area. Just point a fan toward the bulb it blows the heat straight away without any problem.
