Haha....You cats getting crazy technical. And Technically, you are all wrong.
Dr. Fever is on the right track...but dude...don't get all upset.
It's all about the P.A.R. man. P.A.R. Watts specifically.
Photosynthetically Active Radiation
Photons are just the delivery method. Photons out of the range of PAR are useless.
I'm not even tryin' to explain this, so do a google search if you want.
Bottom line, 99.9% of growers only look at the lumens, as this was what manufacturers listed as the the term of "measurement". Folks just trusted that the guys making the bulbs knew what they were doing and the usuable "light" for the plant was maximized, which was the case mainly.
LED tech has started to bring a different understanding of light measurement and thus new ways to look at what kind of lights to buy.
For me, it's all blah,blah,blah.
You worried about your light situation, easy...add another light.
