Light for 10 Gal

Soooo.... i started another planted tank and have been considering my options for light for the past two weeks. I currently have just two of the plain old single strip 15watt t-8 18" blubs sitting over it. One 6700k and the other GE 9325K, needless to say this doesn't look to pretty draws a lot of attention away from the tank. I do have pressurized co2 and ferts on my other tank so i can use all that stuff for this tank also, and i will adjust all according to what light it pick and i need your opinions for that. I am considering three fixtures mainly bc that is all i can find bc the tank is so short.

The first is this

The 50/50 bulb can be replaced with a 6700k bulb the only problem is that the bulb is only 13" long and i need to know if that will effect the lighting of the whole tank since the bulb is not really close to the full 20"

The next one is this

The final one is this

Except the actinic will be replaced with a 10000k colormax full spectrum and am kind of worried about loosing light due to the light fixture being 4 total inches longer than my tank.

They are all pretty close in price so that is not a factor, i will be putting plants in it that came from my 55 gallon light tech.

PLease let me know what you think and which way you think would be the best to go...
