Please forgive me if this has already been asked before, but i am working on a project that compares PF lights with a third party that I already use (lifelights.com). Now, I know that the third party lights are already brighter, but I am looking @ other characteristics. Real quick, does anyone know (more or less objectively, but per speculation) how many PF lights I can connect to one PF battery box without dimming? I want to connect 4 pairs (8 lights) to one battery box, but want to know if it will dim. I have tried it will nominal dimming....but want to see if I can get others' input, and also see if adding that many lights will too quickly drain the batteries. Thanks!!
