Otherwise - http://www.aquastyleonline.com/products/Aquarium-14-LEDs--DIY-Dimmable-Kit.html with 7 white, 7 blue.
I must admit I don't understand the reasoning for using cheap LED's on frag tanks, nano's etc but not on DT's. The problem with cheap LED's is not so much the quantity of the light (especially on small tanks) but the quality - unless you have access to equipment to complete a spectral anslysis you will not know the wavelength of the light being emitted. Other types of light (T5's, MH etc) output a broader range of light where at least some is likely to hit the required spots (and some is wasted because it can't be utilised by our saltwater life forms). LED's are different in that they emit a very narrow range of light - if you miss the peaks in the spectrum required by corals etc then they will, over time, decline.If its for a frag tank i would go with the cheap leds. or if you want to do a "Test" Diy job,
For a display tank i wouldnt personaly use the cheap LEDS.
I would definitely go for the meanwell drivers tho compared to the chinease ones.
