maximum led watts per metre? bandwidths?>

[drspastic]

ok SWIM is fully into flower with nice scrog colas starting to form. currently in 90cm tent with 250w cfl 90(?)w ufo and diy leds: 100w true 660nm 100w true 625-635nm and pink led tape sidelighting @40w . now he has a big bag of led chips of all sorts and can throw oodles more power in. how much can they take before going critical? mainly cheese bag seeds, and possibly get the cfl out of there as it takes up a lot of space. would 400w of the 635nm and 200w@660nm be ok to finish flowering or should he put more, keep the cfl but out of the shade and hang vertical for more led space? add a second 125w cfl? the 100w 660 bars burn the leaf tips unless they are up 25cm above.

there is up to 700w power supply available to fuel the leds, to thats the max limit btw

LEDs do not work on the same math as HIDs (hps mh lights)

they work on a Par rating
http://en.wikipedia.org/wiki/Photosynthetically_active_radiation
all the math and fancy numbers for u to work out the info for self

basically LED give off less light but more accurate for the plants use......so the old system or watts and lumen/lux can not be applied to LED the same way
now as for the amount of power for the most possible output in the end of the plant

not currently sure ..........u want to max out the par ratings in all the area to get that number ( the lights i use if i used 2 of them in a 5x5 area it would max out the area )
