I want to get an LED Light for my 10 Gallon Aquarium.

Problem is they do not measure LED in Watts like they do for T5HO or Metal Halide so I am unsure how powerful they are.

How do you comapare Watts to Lumens.

This Marineland LED system is 1305 Lumens (What does that mean in terms of Watts).

Would that work out for my 10 Gallon Reef Tank (It is only 10 Inches deep with the sand). I am most worried about the Plate Coral on the very bottom of the Tank.

Since the Tank is so shallow could I get away with one of their cheaper models (I am not sure how LED will work out as I have not used them before so I do not know if I will like it or not and do not want to spend alot of money for something that I am trying out).

Marineland Single Bright $42.49 300 Lumens
Marineland Double Bright $79.99 450 Lumens
Marineland Reef Capable $179.99 1305 Lumens

Has anyone tried the Marineland LED systems before? If so what did you think of them?

Thanks in advance
