I'd only spend more for the h600fc mk4 which has hi cri and less tint deviation. Otherwise I'd get mk2 in neutral white which is what I've been using for 3 years now. Max lumens isn't that important compared to tint, cri and beam profile.you guys think the Zebra light MK4 series is worth the $30 more then the MK2 series? 1100lumen vs 1400 for the spot and spill models.
