Best Lighting Fixture Between These Two for a 20 Gallon Long Tank?

[RAWRRitsEDWINN]

I plan on setting up a nano 20 gallon long reef tank. I am undecided about which light fixture to go with.

Marineland LED Double Bright Aquarium Lighting System (http://www.petco.com/product/112418/Marineland-LED-Double-Bright-Aquarium-Lighting-System.aspx)

Coralife Dual Fixture High Output T5 Aquarium Light Fixture (http://www.petco.com/product/113078/Coralife-Dual-Fixture-High-Output-T5-Aquarium-Light-Fixture.aspx?CoreCat=certona-_-ProductListTopRated_Fish_3-_-Coralife%20Dual%20Fixture%20High%20Output%20T5%20Aquarium%20Light%20Fixture-113078)

Which would be the best one to use? Also, what types of coral could I keep under the Marineland? I know under the Coralife, I can keep soft coral, mushrooms, etc.

If you plan on growing corals the T5 light is best, for fish only the LED would work fine.

The Marineland double brite is not meant to be used on a reef tank and their Reef LED probably won't be powerful enough for a 20 gallon tank by itself.

For couple hundred u can get the 24 watt bulbs which will rock the tank...I had the ones evilc66 used to make..They sell all over the place and marinedepot ...they are very versatile
