wpg is apparently an outdated way of looking at light. It works for t12 but anything after needs additional calculation to convert the modern lighting to t12 standard. I think thats how it goes. Over at a huge planted tank net forum, hoppy, a guy, has a lighting chart that can provide a better idea. I base mine on his as i use tube fluoro. Some people use cfl and i dont know how that works out to be low or med light.
Id love to see your setup in pics when youre ready
