Dimmer Switch for LED Light Fixture

Hi!

What kind of dimmer switch can you recommend for this Designers Fountain LED light fixture?:

Designers Fountain LED1101-34 Halo 11-Inch LED

I bought it on Amazon.
(I'm not allowed to post links yet, otherwise I would)

I don't know much about LED lights, so if you could be very specific as to what type of switch I need to look for or even a link to the dimmer switch you think would work best for the light I have, that would be very appreciated.

Thanks!
