my thoughts on the cree cxa

when it comes to real life kids...the numbers.. are just numbers.. you won't notice it in heat build up in your room or on your power bill...its like having 700HP or 710HP...the 10HP might seem like a lot..but in real life it makes almost no difference

True if your grow is not limited by heat, chasing extreme efficiency might not be a positive economy. But if you scale it up to the point that heat is limiting your quality and relying on air conditioning/heavy duty ventilation, increasing efficiency is a solid option.
