Your point was that LEDs don't break even. My point is that there's a threshold at which they would. If you only ever grew one tomato then you probably could buy a cheap plane ticket to deliver it, for less than the lights. So you'd be right, the LEDs would use more energy (cost to make, ship, and use) vs the delivery charges for the sun-grown (free energy) tomato from farther away - even if shipped expensively. But if you grew millions of tomatoes from the same LEDs then you'd be wrong - now buying the grow lights is much more efficient than shipping in sun-grown tomatoes from even a few kilometers away. How many tomatoes are you going to grow?
