If it has tiny 5mm LEDs on it -- it's not good for growing anything. The end. Tiny LEDs, even when corncobbed together into a super duper ooper lamp suck. I have 4 3x3watt GU10 LEDs over a 24" tall tank (it's a tall hex) and it gives me low light at the substrate (bulbs basically on the top of the tank cover) and two of the 10W flood fixtures above my 20L (about 18" to substrate). Stick with multiple (DIY or purchased) 1W/3W LED arrays or the 10/20/30/50 floods, they're built with new high efficiency high output LEDs, and not with chinese VCR leftovers. Mine were 2wire ungrounded, but the case is built with gaskets and grommets to make it "outdoor safe".
