Well the LED light I plan to build eventually would use around 560 watts on it's highest setting. Then I would plan my battery storage according to that max number and the max number of hours I would estimate I need to run it at that power. I haven't done the math yet. I don't expect I could completely cover my needs for calories at such a small scale of one light but it could very effectively grow things like peppers and other crops that have really gone up in cost at the grocery store. If done right a light like that could easily grow in a 5'/5' space with things like peppers on the top and more shaded plants below. The goal would be reduce my dependency of the supply chain but in reality would take a lot to get completely off of it. You would need to do a much bigger garden so maybe the led light gets me the head start my plants need to thrive when the sun hours just are not there like early spring then out into the garden when the sun is there into summer. Hope that made sense.
