I'm getting about 20 of these
for free but I don't know their efficacy, they claim a lot but i'm new to the world of LED lighting. I'm starting a 20g long planted tank in a month once the substrates all set and I'm planning to build a hood out of these
Is this possible, how many are required, is there anyway someone can estimate the equiv to a CFL? my hood schematics thus far plan for eight lights, four of these and four CFL's
I have done some research and have a decent newbie understanding of LED lighting. I was very much into planted aquariums in high school but when I left for college all my stuff was thrown out now that i'm on my own I'm starting up again.
