LED light question
 

I have a 2.5 gal pico with lighting of 18 watts PC I am just starting up again after taking a break. Only keeping zoas, gsp and maybe a candy cane coral but the zoas and gsp for sure.

I was wanting to know about the new Dymax Robo LED light 28 led's on this fixture if that would be strong enough for this little tank and the corals I want to keep?

Depth of this tank is 7.5 inches.

No worries on the reply. Just talked with a guy whom used one of these and after 3 months the lights became alot more dim were not as bright as when he first got it. I will stick with the pc instead.
