Dimmer for Nth-Light Narrow LED Flexible Strip Light
One strip specs are :
12V DC @ 65mA    = 800 milliwatts
LEDs/ ft.: ~1,200  ( lots of tiny Leds )  that seem to be arranged in 96 clusters of 24P4S
Luminous Efficacy: ~30 lm/Watt  ( not great )
CRI: ~73 CRI  typical
Color Temp: ~5000 K  neutral   

So the 8A dimmer is overkill for one strip but shud work.

Any 12 supply can handle this low current but the voltage affects the current used so it is rated for 12.0V

The web specs could be wrong and it recommends a 1A supply, so watch out for voltage tolerance.
