Zebralight/Headlamp

Zebralight H600Fc Mk IV

Name: Zebralight H600Fc Mk IV
Brand: Zebralight
Price: 99 USD
Availability: InStock

A benchmark headlamp. The H600Fc's frosted lens gives a beautifully floody beam suited to trail running and close-up work, and Zebralight's efficiency is still unmatched.

Beam profile

Flood, about 34° wide. Wide and even — light where you are, not where you're pointing.

Estimated from 1,568 lm ÷ 5,800 cd — how this works

What owners report

Zebralight H600Fc Mk IV/5 sources reviewed

The frosted-lens, high-CRI version of Zebralight's flagship right-angle headlamp, and owners describe the tint as amazing and remarkably even, with output and colour rendering to match. Programmable levels and a genuine moonlight mode round it out, and medium-output runtimes on the Mk IV are better than the Mk III generation.

The Mk IV generation drew specific criticism, though. Owners consider its PID thermal control poorly implemented compared with the Mk III, and describe the H1 top setting as unrealistic — the brightest level warms up very quickly. The battery compartment is tight enough that it won't accept all 18650s. There's some light bleeding through the switch at higher levels, and minor cosmetic imperfections in the anodising near the cooling fins. Owners still call it a keeper.

Questions people ask

Which cells fit?: The compartment is tight and won't take every 18650 — protected cells in particular can be too long or too wide. Check dimensions before buying spares.
What's wrong with the thermal control?: Owners find the Mk IV's regulation less well tuned than the Mk III's, so the top level heats up fast and steps down in a way that feels less considered. It doesn't stop the light working well at usable levels.
What does the 'Fc' mean?: Frosted lens plus high-CRI emitter. It gives a pure, even flood with good colour, which is what you want on a headlamp for close work — no hotspot to aim.
Is the top mode usable?: Briefly. Owners describe H1 as unrealistic for sustained use because of how fast it warms. The levels below it are where the light actually lives.
