My tank is 14" length 8.5" height.

There is pressurized co2 with mostly low light plants (Staurogyne Repens, java fern, anubias nana, bateri).The light is mainly for the Staurogyne Repens, i'd like it to grow laterally and not vertically. I'm currently looking at these three:

Amazon.com: Wave-point Mirco Sun 6,500 k Daylight High Output 8-Watt LED Fixture Lighting for Aquarium, 6-Inch: Pet Supplies

Amazon.com: Finnex Fugeray-R Ultra Slim Aquarium LED Light Fixture: Pet Supplies

I have the fugeray R on my 5 gallon pfr tank and love it. all I have is different types of moss and downoi in it.

Based on looking at each fixture I'd say the first two would fit the bill with the finnex likely giving better spread due to design.
