Eh.. looks like Chinese black box lighting. Hard to say how good it is unless you crack it open and see what they did to reduce the price such a drastic amount.
Will it grow coral, possibly, will it look like a Kesill output? eh....
For me the test to one of these lights is to see how many recommended ones there are that look identical.
And I know I've said something similar to you before... if you can't afford what you want want, then don't buy something that will now. This is an expensive hobby and there are absolutely ways to shave off dollars here and there, this light is one of them, and if you wanted this light then I'd say go for it, however you seem to have your mind fixated on Kessils, so why not wait until you can afford a Kessil? Why do you need a frag tank now? That's more expense, how many frags do you plan on sticking in there in the near future? Is putting a little frag rack inside your display tank not allowed?
