The Spike is a mechanical relay. You'll be limited by the physical response time of the contacts. (And you'll eventually wear it out if you switch it too often, though it's probably in the tens of millions of switching events.)

And is there a way to dim the strip via PWM? Should the strip be 5V for PWM control?
If you want 12 volt dimming, you can use a speed controller such as a Victor or Talon.
