i dont know what the difference is but i used the "blue" ones and they work. i wish i could help you with the differences. maybe WEEZARD will chime in and help out. i used the meanwells and they work well although i used different drivers for diff wavelenths so i could control the spectrum kinda and am not sure in your case which would be more efficient. cant remember where but read somewhere that the life of the led increases(correct me if im wrong please).
anyway hope what i said helps.
good luck
