Yes those are what we call "Ebay LEDS". Many people use them and have had great experiences.
WARNING: Some say the full spectrum has an extremely purple hue.
Check the chip on the LEDS because some of them use Epistar chips and not Bridgelux.
One of the blue/white fixtures will work if you would like also.
Keep in mind the hanging kits that come with these aren't the best. Buying some extra cords may help some. However there are some stands for them out on EBay.
Carey, an aquarium advice user who has replied earlier in the thread, has had lots of experience with these. I would ask her for opinions or pictures you need on the lights.
Since the tank is a 20h (Like Mine) you will need to dim it down quite a bit. I have been told that it may be under 50 percent. This light can burn through corals easily. You will have to acclimate them very well. (That's what I have been told.)
It has been said that they do break, but are simple fixes. You may need to replace ballasts or things like that every once in a while.
These are certainly a good choice, but they are not your only option. Keep in mind "You get what you pay for."
Sorry for such a long post, haha.
Bribo: Sorry about the kessil thing. My mistake I hate to give out false information
