i've got a few, all current models (mk4)
H600w headlamp, SC64w HI, SC600w Plus, SC700d
and i've tried SC64c LE, H600c headlamp, H600Fc headlamp, H600d headlamp
really, i think that zebralight is a very difficult product line to understand. probably one of the worst marketing jobs i've ever seen.
i get that they cater to light geeks, but i wish they or someone else would make an article or video breaking down all their current models. model number explanation, comparisons with each other, usage suggestions for each model, etc.
i've looked at their spreadsheet a bunch, and i don't know that i fully understand their lineup. if i did, maybe i'd own even more of them, hah.
