Greetings,
Lighting is an important and confusing subject.
While I do not claim to be an expert, but I would like to relay my understanding of the subject.
First, you can get a light with a certain light output. THAT, would be lumens. THAT would be total light output without regard to direction of the light.
Second, you have LUX and that would be the intensity of light. Lux is what you would be interested in. In other words, what is the intensity of the light on your plants.
Who cares about the lumens, because your plants do not "see" the total light output of your lamp.
So I got a light meter. It measures the intensity of the light at a single point. The measurement is in LUX.
I found out that my cheap reflector creates hotspots 50% of greater intensity. I moved the shortest plants to the brightest points and It told me which plants were getting too much and which were not getting enough.
