Welcome from Mexico.

1500cc per minute = 1.5 lpm so it should be ok.

Looks like you have 12 LEDs, so they are probably 1 watt each. If so you can start with those.

Ok if you run them with 500ma then they should not be too much.

You will need to operate them in parallel: a series of 6 leds, in parallel with the other series of 6 leds. This will give 500ma to each led.
