These are effectively the exact same thing as the Marineland Double Brights except they are much cheaper (although they are not known to be high quality).
Pros:
Cheaper than the Marineland version.
Cons:
Known to be hit or miss at best for quality.
Horrible LED arrangement. They are big LEDs spaced out too much so the tank isn’t lit properly.
Summary:
Don’t buy them. Look in to Finnex for fish only tanks.
