LED bublb calcs
Alright I scrapped/sold my LEDs and and the parts I had bought for my S/W seahorse tank light array. Anyways I have a little Finnex 4 going right now and would like to move to LED for this. The dims are 12 x 7.5 x 10. Its a slick little tank and deserves a slick light. The stock light, and a HD light on it does not look good. For that matter I just do not like PC flour at all. I had been considering setting up a custom built 15 gallon and then getting one of the GLO dbl T5 units but A) the cost of a custom tank is yikes!!!, and B) the stock in the custom is likely to be blackwater crypts, java fern, anubias nana etc so the T5 most likely would not work strung over both tanks.
Anyways the long and the short is how many 3 watt Crees do you think I need to have med/high light? I am thinking 8 white 3 watt Crees, and a few red and blue added in. Not sure how many on those either. Not sure if the eight would be overkill, but they will be dimmable so I am not worried too much just don't want to piss money away. Then if I turn this tank into a mini reef sopmeday the lighting will be mostly in place.
