Ok im here to help everyone who is getting the wrong information from people saying Lumens dont add up (when they do but a FLUX just cant belend them together as it is metal so how people think it could pick up anything else WTF
dont listen to people who have only use a flux and said it dont add up .
as they do add up not with a FLUX but the plant will lol
use as many as you can the more the better.
thanks for listen

If lumens "added" (they don't), a lux meter, which measures light intensity (1 lux = 1 lumen per square metre), would show a doubling of light intensity per light source added, it doesn't.

You're confusing light intensity with light coverage. Two 1300lm bulbs may cover more area with light, but it's the same 1300lm intensity.

No your not understanding me .
everyone say lumens dont add up (on a flux if you get two bulbs next to each other so whats the point)
but a plant doesnt read light intensity like a flux which is metal no shit its only gonna pick out one intensity .
its not about adding all the lumens to one leaf but riseing the lumen in a total per a sq/ft

becuase i have
1 x 125w 12000 lumens and 2 x 85w 5500 lumens each Just at the top but i understand what your saying its right as a light bulb can only be one (max) intensity but you cant base your fact off a FLUX damn

No brother, you're not understanding.. First of all, it's "lux". which is a unit of measurement equal to 1 lumen per square meter. It is measured with a "lux" meter. A "lux" meter uses photovoltaic sensors to generate a voltage proportional to light exposure. That is how light intensity is measured. Unfortunately, at this time, we do not have a method to measure light intensity with plant leaves and translate that to luminosity.

Like I said before, you are confusing intensity with coverage. You can jam all the 1000lm bulbs you want into a space but it will still be 1000lm. The more 1000lm bulbs you use will only reduce the loss of your original 1000 lumens due to distance.

"You can jam all the 1000lm bulbs you want into a space but it will still be 1000lm. The more 1000lm bulbs you use will only reduce the loss of your original 1000 lumens due to distance"



but its like i said last time its not about getting a 1000lumen bulb to get more than 1000lumens which is impossible , and not to get 2 x 1000lumen bulbs on one leaf.
ok mayb in a lux's view but you cant say what your saying for a plants point of view.
so is it true to say a plant on average wouldnt grown bigger if the sun had the same light intensity but 2 times the mass .
No way

and if that was true a 125w 12000 lumen bulb would grow the same size plant if it was in a reflector than 5 125w 12000 lumens with or without a reflector
Dont think so

lol its like saying a (big mass) Big fire and a (small mass) Small fire has the same heat (energy) No

If the sun increased in mass and therefore energy, then it would increase in luminosity. If there were two suns of equal size/mass/composition it would bring no increase in luminosity. Just more coverage. Therein lies the answer to your confusion, you aren't increasing the brightness of your bulb by adding another bulb, you are simply making more of the same brightness available to a larger area.
