1 400 watt light goes nicely in a 3x3 room so 2 in a 2x2 room is way a lot. you can use a 150 in a 2x2
yeah it does seem like alot to me too.. but untell i see negetive effects from my plants( not yet thank god) im running it... and i still have 1 more 400watt thats going in there...im trying a micro SOG so i want small plants with only a 1 nice cola on it....:mrgreen::peace:

all that extra light is useless why wouldnt you just grow more in a 3x6 room. it really bugs me, its just a waste you will get no benafit from it and it may cause problems and it will actually impead your grow with all the heat and eccess light its just not right 400 w in a 3x3 is all you need and your goin 8oo in a 2x2 thats just not what i would consider intelagent dicission makeing good luck with your 2x2 closet full of stupid. your gonna get like .0001 gram per watt

While many say "you cant have enough light", I beg to differ. Although it is improbable that you would experience too much light on small operations, it is possible. One sign would be that the leaves will start to bleach. I cant give you an exact number as to what would be too much, but I doubt you would spend that much money to get too much light to begin with. It should not be a major concern.
please can you put a number on it? i am rockin 1400watts in a 4x6 i just wanted a larger "sweet spot" plus i have 4 ballasts laying around and for that space i think 600watts would be good, but the girls outside of the sweet spot would suffer, thank goodness i have air cooled hoods

i thought i was being excessive, but that 2x2 at 800watts is bonkers

i dont know if 7000 lumens/sq ft s all you need... i saw significant gains going from t12 fluoros, 100mh, to 400hps, to 1400hps, to 2000hps.... i'm now at 16,000 lumens/sq ft and they can deal with it... and thrive. my temps stay under 80 with air cooled hoods and ballasts...

800 watts in a 2x2 space may not work, that is a bit excessive - you prob wont be able to get the heat out... and that is 27K lumens/sq ft... almost double mine, which is probably one of the most light-packed gardens i've heard of...

Yes these bulbs are great. My plants showed zero stretching when I turned them over to flower. $220 is alot to pay. And it's all mark-up. I've seen the distributor's price and Hortilux sells them to your growshop for about $120. It's the man behind the counter selling them at $220. I got mine for $150 a piece.Still expensive but way more reasonable. As far as the bulb goes it's awesome.This bulb gives off two different colors of light, red & blue. It's rated at over 110,000 lumes. Best of all, it works with any hood and HPS ballast.

both of those sentences seem to mean entirely different things...

i did a little bit more research... seems like the accepted number for highest sunlight intensity is 10,000 lumens/sq ft... the highest i've heard of anyone recording is 13,011.

by my count each 400w light should be producing 55K lumens, totaling 110K.

he's running with 4 sq ft of floor space... so thats 27.5K lumens/sq ft...

27,500 lumens / 10,000 lumens = 275% brighter (best case)
27,500 lumens /13,000 lumens = 211% brighter (compared to highest value i found recorded)

either way - its really bright - the pics i'm sure dont do it justice, because your monitor cant blind you ;-)

make sense now?
