How big of an led to replace a 400 or 600 hps?

You cannot think in terms of replacing an HID with an LED. They are completely different animals. One is successful by flooding the plants with huge amounts of semi-usable lumens and the other is a very low intensity light that has nearly 100% usable lumens. You really cant compare them at all.
I have a 4' x 2' x 5' grow tent with a 90 watt led from htg supply and 110 watt t5 running power cost is very low and with both lights going they put off little to no heat to speak of i have only 2 plants going at this time but all is working out great. To me the benefit of the led and t5 lights are you dont have all the heat to vent off like you do with hps or hid lights and you do not have the extra cost on power. Good luck with your grow and be safe.

i would go with several smaller leds. better coverage, more wattage. 4 pro grow 180's will cover a 5x5 at just half a foot away from canopy, they each pull 160watts that will total 640 watts. that will out perform a 600 hid probably even a 1000 hid. that will run around $1100 for all 4. or around 300 each. but the more you buy the more they discount.
for led thats the best deal for the money. better leds cost 3 times as much. but perform close to the same
also lumens are irrelavent. lumens by definition is visible light to the human eye. plants dont absorb that spectrum of light. they absorb high blues and reds and low greens and yellows

^^ This. I have a PG 180, but after using it for 2 months, it is only good for 2-3 plants at most. If another LED panel has the same dimensions but more wattage, I'm sorry, but the effective footprint is not that much better.

I think your right.. you cannot compare the 2 to each other. But we can compare plants grown under both. Anyone have any success with LEDs start to finish? I used t-8s for my first grow & it worked for me. NOt as good as I get now with HPS.. but still certainly smokable. DEpends on what your looking for I guess.
3 is max? What do ya mean
