I started this thread thinking about the lumen decrease due to distance http://boards.cannabis.com/advanced-...e-formula.html . But the only way to figure out how many lumens are where is with a light meter it seems.
And I know about how decieving the wattage of light you use is compared to the power it uses, but thanks anyways.

Well light loss per range to source is not difficult to calculate.
It goes down exponentially and that means double the range cost your lumens to decrease to a 1/4. Exactly.
However that does not take into acount leaves that shade or other distortions and reflections etc. But from light source to top of the plants it is perfectly accurate and a basic physical fact of nature. Same thing with drag by the way was a racedriver before. Double the speed = quadruple the drag.

Interesting thread by the way man. And ye I am very much into numbers, statistics and calculations myself.

Alright I've been researching, brain storming, tokin', and drinkin', trying to figure out how to put my lighting system to it's optimum use. I'm working with a 1,000w HPS system. Thats with a MH conversion bulb, and eye hortilux HPS bulb I've figured the numbers with 3 possible garden sizes 4x4, 4x5, 5x5. I'll start with the brightest. 4'x4' area=16 square feet or 62watts/ square foot HPS=9,062 Lumens/ square foot MH =6,562 Lumens/ square foot 4'x5' area=20 square feet or 50watts/ Rating: 5
