I would steer clear of marineland LEDs. I think they are overpriced for what you get, especially for your particular application. A screw in CFL bulb in a brooder lamp works extremely well for a fuge (it is what I am running and my chaeto is growing like crazy) and costs only a few bucks. If you want to light the fuge with LEDs, consider building an appropriately sized fixture with parts from rapidLED or look at trulumen pros imo
... much more powerful LEDs. Taotronics LED
fixtures (sold on ebay) are also much more bang for the buck than the marinelands.
