looking at the specs on the site for that LED and it seems as though it will add nothing to your grow, for one it doesn't specify the wavelengths of blue and red and I doubt they'd be correct as its basically for entertainment purposes.
even as a side light I'd say it's useless... (unless it has somewhere in the manual or something better specs on the spectrum's it uses, what you need is something like - 660nm Red, 630nm Red, 425nm blue and 450nm blue)
And if possible get the CFL's close as you can.
other than that, your box is brilliant, kudos man!
