I have some t-5 2' fixtures. One is rated at 8000 lumens. Now, since they are 2 foot long tubes does that mean that every plant under that light (which is within 1-3" of my plants, is getting showered with 8000 lumens? Since it covers an area roughtly 2'x1' does that mean that it is basically 8k lumens per square foot? Or does that simply mean that the 8000 lumens is spread over the entire distance the lamp covers? I understand CFLs and HIDs where the light more or less originates from a single spot and all the light is spread out from there. The plants closest to the ligths are going to get hit with the fullest force of the light. Is the same true with tubes? Or is the light just more defused?
So if I had 1 cfl with 8k lumens and a my t-5 with 8k lumens in the same sized space (1.5'x2') would the growth rate be more or less the same? Providing everything else was the same that is...
Sorry if this is a really simple and stupid question that has been asked a million times, but I did browse the stickies before asking.
