i just read this in one of the sticky that conflicts your last statement:The power of the energy. A 1000W light is putting out over 100,000 lumens at its source. That is intensity. Now, as you increase distance your intensity drops by 1/2 per 1'. So at 1' your intensity is 50,000 lumens. At 2' you intensity is 25,000 lumens and at 3' your intensity is at 12,500 lumens.
Now, take a bulb that has 1100 lumens. At 1' you have 550 lumens. At 2' you have 275 lumens and at 3' you have 137 lumens.
Now take 2 bulbs at 1100 lumens. If they are on either side of the plant the plant is getting more lumens but not more intensity of light. The light simply does not penetrate as far with smaller bulbs and it does not add up. You could put 10 bulbs at 1100 lumens and 1' away your meter would still read only 550 lumens.
"What this means is that if you put two lights the same distance from a point, and each light provides N photons per unit area at the point, with two lights you will have 2N photons per unit area at the point. Because intensity is a measure of the number of photons per unit area, the light is twice as intense, whatever unit you choose to use. Twice the lumens, twice the lux, twice the footcandles. "
edit: and this also proves cowboylogic wrong, BUT im not trying to prove anyone wrong i just want to know the truth cuz i get a different answer from different sources. RRRGGG this is confusssssing
