For tank, it depends on their placement, tank size and depth. But it is obviously an overkill for 10 gallon :P

thank you. i guess what im trying to figure out is, are these things useful (im looking to light a standard 120 gal and 40 gal sump)? im a total noob when it comes to led (and reefing really in general), and dont even know where to start. these drivers are available and if the price is right, i figured i might be able to build a half decent fixture? what does it cost to build something like this? where do i start? how much would i save by using these drivers? would i be better off with a different driver entirely? what am i getting myself into? should i just walk away now.....
