Zebralight H600c Mk IV Headlamp - 4000K High CRI, 18650, IPX8

Precision lighting for night work and outdoor adventures

The Zebralight H600c Mk IV headlamp centers on a Cree XHP50.2 neutral white LED, delivering a 4000K color temperature and a typical CRI of 93–95 with a tight 17° hotspot and an 80° spill. This pairing helps reveal colors and textures in low light and on the trail, aiding clarity without harsh tones. The tint deviation is controlled to minimize color shifts across brightness levels, ensuring a dependable, natural feel whether you’re mapping a campsite, inspecting gear, or reading a map after dusk.

• Three main brightness levels (High, Medium, Low), each programmable to two sub-levels
• Second sub-levels can be set to different brightness values across main levels
• Operating voltage from 2.7V to 6.0V; uses a single 18650 rechargeable cell (not included)
• Thermal regulation maintains steady output on the highest settings

Smart controls and durable construction

Designed for reliability, the H600c Mk IV features a smart user interface that provides quick access to all brightness levels and beacon-strobe modes. The unibody aluminum housing is precision machined and bonded to the LED board for efficient heat transfer, while a durable Type III hard anodized finish adds protection. The device is sealed and IPX8 rated for submersion up to 2 meters for 30 minutes, with built‑in battery protections and a continuous temperature/voltage monitor to guard both light and battery life.

• Soft-touch electronic switch offers responsive, durable operation
• Tempered optical glass paired with an orange-peel textured reflector for clear, balanced beam quality
• Battery capacity indicator flashes to show charge state
• Automatic stepping down from High to Medium and Medium to Low as capacity declines to preserve runtimes

Real-world use and benefits

In practical terms, this headlamp provides versatile light for night routines. The neutral 4000K output with high CRI helps you spot details—textures, labels, wiring, and trails—without overwhelming color shifts. The compact 0.95 inch head, 3.85 inch length, and light overall weight ensure comfortable wear during long sessions, while the beam geometry balances distant visibility with broad peripheral awareness.

• Night hiking, camping, and outdoor maintenance with hands-free lighting
• Under-hood tasks or workshop work where precise color rendition matters
• Navigation and map reading in low-light conditions
• Search, inspection, and quick tasks around the campsite or garage

Specs and compatibility at a glance

Weight is approximately 1.4 oz (39 g) without a battery. With a ZL635 battery, it weighs about 3.0 oz (84.6 g); with the battery and headband, about 4.4 oz (124.6 g). The head measures 0.95 inches in diameter and 3.85 inches in length. It operates on a single 18650 cell (up to 69 mm) within the 2.7–6.0V range. A PID thermal regulation system helps keep performance consistent, while robust protections guard against typical battery issues. Built to endure outdoor use, the Zebralight H600c Mk IV pairs thoughtful design with practical, source-light performance that suits a wide range of nighttime tasks.
