I really don't think anyone can tell you which one is the "best" light out there.
The AquaTop SkyLED 36" Aquarium Light is using all <1w or 0.5W per led
The are less than 1w per LED
which means they can't really penetrate that deep into the tank. It is a lot less efficient than the 3W bulbs.
And most of these are generic brand LED
and you can't really tell about the LED
In order for you to choose the right fixture,
You should plan ahead.
What are you going to keep in your tank?
How much is your budget?
Are you capable DIY and still feel good about the product you make?
There isn't really a fixture out there can be efficient and low cost at the same time.
The less efficient fixtures/LEDs usually mean they are much cheaper, such as those fixtures using bridgelux LED
However, it can't beat CREE or ES luxeon in quality. (PAR/PUR output)
The cheaper fixtures can also mean less control over the fixture, some of them only have on/off bottun such as the Onyx made by the DYI guru rapidled.
Some of them has some control such as dimmable knod but has no timer, such as the Reef Breeder value fixtures.
And some of them has timer/auto dimmable option etc which is like some higher cost fixture made by reefbreeder or those that I carry.
And the last one would be those that can have extra gimmick such as cloudy effect/lighting effect/wireless controller etc.
So all these are all depend on you. All these fixtures are able to do a great job when apply them properly.
