I've had different strains running under different lights so it's a tough call. Factor in that I'm just learning to grow and that adds to it.
Once I sex the 5 jilly bean I have going and get some clones I plan on doing some sort of test between all the lights I have. Thinking of doing 500 watt LED vs 600 watt HID vs 400 watt HID + LED or something like that.
At this point I've only harvested a blueberry and chocalope. The blueberry was around 2 ounces and the chocalope was around 2.5 ounces. Blueberry was primarily under HID and chocalope was under LED. But from what I understand chocalope should have a higher yield so I can't say lighting was a factor.
