I am doing research with LED lighting for Aquarium use. I am new to aquariums and cephalopods but am loving it. I am also an electrical engineer and it occured to me to try to build an LED lighting arrangement for my Bimac tank. As I understand it Octos have no light requirement so I figured that I had room to play. I am posting a picture of my aquarium lighted with White LED's that consume less than 10 watts. I wanted to reduce electric use and reduce heat introduced into the system and to increase the useful lifetime of aquarium lighting. Would anyone be interested in having an LED lighting system?
