I am having trouble deciding if I want to go with a 72" light or 2 36" lights. I am looking at the Beamswork LED but up for anyother suggestions can anyone post some pictures of their lighting setup and coverage? Also the LED lights with the lunar bulbs are those just for saltwater or will they work for freshwater too? I am thinking I want to be able to see my BGK when I get him at night! any help would be appreciated thanks!
