Usually, 6 to 700 watts in an led will get you close to 1000w hid. Fluence grow lights are used by the pros to produce some of the best bud available. The bar lights run cooler and you can bring them in close for dense bud.
I agree its kind of comparing apples to oranges or maybe in this case Sativa to Indica's
It's not easy with LEDs that's for sure. The angle of the lens can make a difference. HID definitely works but heat and electric bills are the issues.
