The 2nd tube seems the best for planted tank. The lumens are at 3350 and the color temp at 6500K.

cos most are selling philips brand.

i've been using 3800K MV for my 2ft tank, no problems with plants
apparently it's more the intensity plants look out for, imo
the CRI is important for achieving true colour tho
MV is very bad at that
