    Led light recommendations.

    I was thinking of buying a 2000w led light from Amazon, but there are a few different options. What should I be looking for in a LED light? I had a 600 watt one before but I know that is not strong enough.

    Watts per square foot?

    I recently changed from blurples to quantum boards, I have 240w (2x 288 boards) in a 4x2 tent giving me 30w per foot. Ive heard this is the figure to aim for! My question is, is there an upwards limit? How much would the yield benefit from pumping it up to 50 or 60 watts per square foot?
