Drive a 12V, 16W LED stripe via turning PWM

http://www.ls-light.com/products-cn/residential/emotion-cn/strip_led_flex-cn-detail

It's hard to find more details about it. My version is working with 7,8w per meter.

I conneted the L293 just with one pair of LEDs on the stripe for testing.

I'm not really into mosfets tech. I know that they can easily controll RGB LEDs but is it possible to
rotate the polarity in a really high frequenz?

thx for your help!
