Ok I'm building a scrubber. I want to go with LEDs for lighting because of the space savings, heat level and efficiency. I need help. I've got a rather large scrubber, 10"X6". If we go by the watt per inch guideline fat means I need 20 3 watt LEDs. Is that right?
I may cut it way down. I have a 120 gallon SW tank. I feed a lot! I figure bigger is better? (Like most of 'Merica does)
Let me know if this sounds right. ATM I have a 23 watt cfl to get things started. It's better than nothing, no?
Also if I do cut down the LEDs to say 4-5, what drives are you guys using for such a small number of LEDs and what let silly?
Thanks and sorry... I'm such a newb.
