Hi, very new to these forums, but have been following the great lighting debate pretty close. Not enough lighting knowledge to have an opinion yet, but do have a question. I understand more watts per gallon the better, but what about length? If you have a 4 foot tank for example..... would say two 2 foot bulbs(one on each side of the tank)at 50watts each be 100watts total or 50watts total covering the whole tank? Would they then be equal to one 4foot long bulb at 100watts? I guess the real question is.....does length matter.LOL https://www.saltwaterfish.com/vb/newt...ewthread&f=15#
