QUESTION, YES ANOTHER!
I was cleaning my tent tonight, and just messing around with my ladies. I love doing that.
I had my cell phone in my hand and decided to just use my lux app and move it around my tent
for sh**s and giggles. Over and over these were my approx. readings:
3" under and between my (2) 23w 6500K/1600 lumen cfl's it was reading around 9-10,000 lux
3" under and between my (2) 42w 6500K/2600 lumen cfl's it was reading around 4-5,000 lux
(and 8" under the poor 300w LED only was pulling about 4,000, if)
both sets of cfl's are positioned exactly the same way, in a splitter, but they are from different companies.
HUH?
I know that lumens it is the amount of light radiated and perceived by the human eye, not plants... and I know that Lux is the illumination intensity of an area...but logically wouldnt more cfl watts/lumens mean more lux in the same area tested? I even downloaded a second app and got same results. is it that the little ones are more compact, smaller, designed differently and their light is more intense in a certain area?
so, if we are talking cfl's in growing, which would be better, having the larger more watt cfl's with less lux intensity below them....or the little ones with less watts but more lux?
I think to much.
