JBJ 6G Nano cube lighting

[ladyshark]

Hey all

I am researching pico/nano possibilities for LPS, mushroom and a jawfish.

Space is an issue in my office, so I am leaning toward smaller footprint for a desktop tank.

I am not sure how to analyze LED lighting needed for low to moderate light corals. The JBJ 6 G nano cube has:

LED Bulbs: 6 total: 3 blue, 3 white
LED Total Output Wattage: 7.8W

1.3W blue high intensity LEDs and 1.3W white high intensity LEDs

Is this sufficient lighting for these corals?

Also, so long as I have at least 3 inches sand, is this tank large enough for a jawfish?

Finally, anyone have experience with this tank?

THANKS
