Happy easter everybody!
I have a question, i have seen it debated a couple times but for the life of me i cant find any threads on the topic.
I have noticed recently people advertising that they have for lack of a better example 2x42 watt cfl's. some users assume that since they are getting 2500 lumens out of each bulb that their grow room should hold 5000 lumens.
I have always been under the impression that lumens could not be "stacked". However, 31 flashlights shining on a spot on a wall will be far brighter that 1 flashlight....so i dont know
Can anyone help clear this up?
