New Led Light Questions

I am in the market to get a new led fixture for my 46 gallon bowfront.
Just wondering if one of these would be sufficient to grow both lps and sps?

120 Watt Aquarium LED 20K 3 Watt LEDs 2:1 Ratio LEDs 120W

120 Watt Aquarium LED 14K 3 Watt LEDs 1:1 Ratio LEDs 120W

Would prefer to get the 20K Light. Will I still receive sufficient growth from that fixture>?

 

I would stay away from the no name or less used fixtures as they are relatively unreliable

 

some people on here have had some good success with their taotronics they got. they posted their reviews in the led section its a similiar price point to what your looking at for a premade fixture.

I currently have a 14k one from this site on my 33 gallon and so far no issues...runs great.
corals are thriving. That's not saying anything about this fixture long term as I've had it for a couple of months.

Is there any other fixtures that are proven to be more reliable and available to canada?
Price range maxes out around $250-$300

Also will I still see sps growth running the 20k? would prefer a little more blue to my water
