Current LED Lights
 

Saw these on DR foster /Smith- do these throw off enough light to be of any value as supplemental or on a small nano tank ??

I think it says they are 4 watts.

They have them at aquahut set up on a freshwater tank, if you go you can get an idea of how bright they are. To me they did not seem like they would supplement that much.
