Bro,
As you do not know how many LEDs we cannot actually tell you the type of LED is use.
But you say 11 w over 2 ft, assuming 2 inch 1 LED, 24 inch means there there are around
12 LEDs.(I assume each strip is 11 w)
A simple calculation show us that the LED use is less than 1 watt per LED.1 watt LED is useful
for lighting up your cabinet and furniture only.
For aquarium you need a 3 watt high power LED.
I hope that give you a better idea
