Do parabolic reflectors get better yeilds?

Hard to say for sure; the answer depends upon what you are comparing it to. If you are comparing a parabolic with a cool tube there's no question it will spread the light more evenly but without ducted venting and in a tight space the parabolic would also throw a lot more heat. Parabolics work best in a large grow area where an a/c or other external climate control in used but its not clear if a parabolic reflector would outperform say a large angled style hood. Both distribute light better than a bare bulb would and should produce similar yields if given the same wattage, strain, and conditions. Temps in my experience are way more important than reflectivity and wattage governs yields for the most part. Reflectors just help distribute the light evenly; IMO you won't see a huge difference unless it's in conjunction with a lighting upgrade.

apollo 11 i use these parabolic i love them . i have a huge area to cover . work very well with 1000 hps . spreads out to about 4.5 round . heat could be a serious issue . look at this informative video .
if you do not have a dedicated ac unit the parabolic is not for you . not suggested for a small space

Yeilds ..? No! but any light functions better
the real deal is the build up of heat in the top most area
this heat trap is a real issue
the choice really is 'added reflectivity' versus venting that heat
my first parabolic reflector was just too big
good luck
