Ok i need a light system that is capable Of 80,000 lumens... Wtf do i need to get???
thank you.
thank you.

deppends on what u want to work with ,u could get two 400 which is 110,000 lumen

i dont think lumens compound on each other like that...

u know thats a good question if they add on or not because im useing 400 hps and 434 watts cfl ,how would lumens pan out from differnt points, or is that were lux comes into play

i actually need about 90,000**
i read from a reputable source that the minimum recommendation of lumens to space is 3000 lumens per sq. ft. my box is approximately 30 sq. feet.

"How much light is needed for growing?
Depends on the size of plant you are trying to grow. I'll try to answer this "in general" instead of being specific to one size plant. Light seen and perceived with the human eye is measured in Lumens. There is an ideal amount of lumens for growing and a minimum amount of required lumens. The very minimum amount of light required for smaller sized plants grown is around 3000 lumens per square foot."

i think having two lights just gives you better shadow coverage. you can increase thc content slightly if ones red and the others blue during budding. but i think if u have a 100,000 lumen hps bulb, and another 60,000 lumen hps bulb running right next to each other, it would read on a light meter at 100,000.
Either way what the guy above said, you want a 600 watt digital ballast mh bulb for veg, hps bulb for flowering. Thats the standard go-to lighting system to put out 80k lumens. HTG supply has some decent deals, outside of Amazon, but cant vouch for quality or anything for the Amazon products.

and warrengjustice you just need a 1000 watt hps with any higher end bulb. they make ones that push 140,000 now, but thats more than u need.

http://www.amazon.com/600-HPS-Maxlume-Bulb-lumens/dp/B004CT6T8C oh hey look! theres a 600 watt, 90,000 lumen bulb! YAY FOR SAVING MONEY OF ELECTRICITY!!! it may not cover your whole area thoroughly though.

here we go again... Yes they can, in special cases. Take a LED CHIP that has 100 1 watt led matrix. Technically, each LED only makes 90 watts, so if YOU think compounding of lumens is impossible, then how can a bunch of 1 watt LEDs make a 9000 lumen lamp? The answer is clear. Put 3 HPS bulbs of 400 in the same reflector hood and then tell me that isn't going to make 1000 watts look darker. C/0

There's a whole stickied thread all about this right here: https://www.rollitup.org/indoor-growing/83128-lumens-lux-adding-all-up.html
In short, yes the lumens do add up.

give me like 20 min and ill put up a pick of the new cab i just built. its much bigger than any other boxs ive made.

Since two bulbs will light twice the area of one, of course lumens add up. Why is this even in question?
I would add here, that lumens are designed to measure light seen by the human eye. As a first approximation, they're OK for comparing lights used for growing plants, but really the better measure of plant-growing light is either "PAR" ("photosynthetically active radiation") or "PUR" ("photosynthetically useful radiation").
The reason is that plants grow best using light frequencies that are NOT the best for the human eye to see with.
As a result, you can have two different lights putting out the same number of lumens, yet one be much better for growing, since it has a more plant-friendly spectrum. In part, this is one of the theories behind LED lighting; you use specific LED diodes that put out light that plants like.

sorry i couldnt put the pics up sooner but here ya go.
its 3 feet tall, 5 1/2 feet long and 2 feet deep.
i built it yesterday and made some holes for fans and cords. not sure what system i may try but im thinking about giving HPS a shot. ive been looking on HTGsupply and i really dont know exactly what ill need yet.
any suggestions to make this mofucka badass?
let me know, i know you guys can help me!
THIS BOX HAS BEEN TESTED AND CAT APPROVED!

haha awesome cat. but you will need an inline fan in a small area like that with probably an exit for all that hot air or you will fry your plant with the hot air. just clean that bitch before u stick any babies in there!
and these guys are partially right. if u have two lights spread out, of course it will light up twice the area. but if u have 2 80,000 lumen bulbs right next to each other, its still gonna be 80,000 lumens just less shadow area. but like jogro said, lumen suck. they are very confusing things and lux just makes it worse. thats what will increase. its like this, at sea level the suns light is at like 100,000 lumens, but if they have bulbs that put out 140,000 lumens, why is the sun still infinately better? because its everywhere. like, my flourescents at bulb hieght put out 3200 lumens each but only around 400 lux. its just wierd.

i was suggested in the Growroom and Design setup that 3 150watt setups would be perfect in there. idk tho

ya that would work. prolly slightly less bud density than a 1000 watt, but this way u can have the middle bulb to a blue spectrum and raise your thc content a little bit.
