I have used Marineland Double Bright LED lights in the past. I want to warn others not to.
Pros:
It is an LED.
Cons:
I can’t stand the light arrangement. They are large and spaced out. This makes the tank look like it has a bunch of little spotlights everywhere, not the nice even, filling light you can get from other light types.
They aren’t bright enough to do much with.
They are expensive.
Summary:
You can get much better lights for less money. Look in to Finnex for fish only.
