Really after reading the information, why aren't we measuring by lumens? It seems to me that just going off of straight WPG is extremely inaccurate. I went with 2 WPG on my 55 gal based on that but my two bulbs will probably be putting out at least 9,000 lumens. At 2 WPG I'll be the equivalent of 3 WPG of NO bulbs.
I know this is all covered in the stickies but most conversations here still seem to focus on the WPG rule. I think maybe we should consider a new 'rule of thumb' scale for PC bulbs since they seem to be popular. Cause I know all of the different bulbs and terminology really had me confused when I first started thinking about plants
