Need someone who knows about LEDs to help. I have found a 36 inch LED fixture with 2900 Lumens of 10K light. And am considering purchasing 2 fixtures to cover my 125G tank. How much light would this give me? Both fixtures would provide 5800 Lumens of LED. Tank is 24 inches deep. Would there be enough light or would the tank be too dark? Would there be enough light for low light plants? Thanks for your input.
