I recently bought a Zebralight H600Fc MkIV. I’m really pleased with the light and tint. High CRI in 4000K is my favourite. Previously, I only had Nichia 219B emitters with that tint, but the Cree XHP50.2 seems to match it with much higher efficiency. At least with the frosted lens, which probably smooths out any beam imperfections.

This light also seems to give a lower moonlight option than my other MkIV models (SC600w HI, SC600w Plus, and SC64w HI). So, I’m pleased to have that option, even though I tend not to use the lowest moonlight very much. But, it’s good to see they’re offering the lower moonlight again, like they used to have on their older models.

Frosted lens is a really nice option for this headlamp. Great visibility up close, but not the harsh shadows you get from the mule version. Headstrap is comfortable, too.

I have a couple of Armytek lights (not a headlamp), and they’re nice. I prefer Zebralights, though. I like their UI better, and the feel of the body and switch.
