After a trip to Costco, I came back with an experiment. A pack of 2 battery operated, 6-light LED lights for 1,777 yen, (15 bucks). After some velcro we have 12 LED shining down into the tank. They advertise as running 10,000 hours on the batteries. So is this going to work? Is there anything different about these LEDs and others made for aquariums?
So far this is a fish &
live rock set-up so light is not critical. But I would like to add some low-light corals as I go along. Let me know if I am doing anything disastrous.
