Overview
High-output 18650 headlamp built around a 4000K high-CRI Cree XHP50.2 LED with a programmable multi-level interface. The machined aluminum unibody, thermal regulation, battery protections, Gorilla Glass and IPX8 waterproofing support demanding field use while output spans ultra-low moonlight levels through a 1616-lumen high mode.
WHAT MATTERS
4000K High-CRI Output
Cree XHP50.2 neutral-white LED is rated at 4000K nominal CCT and typical CRI of 90+.
Programmable Multi-Level Interface
Three main levels and programmable sub-levels provide access to twelve brightness levels plus beacon and strobe modes.
PID Thermal Regulation
The three highest output levels use PID thermal regulation, with user-adjustable regulation temperature.
Machined Aluminum Unibody
Precision-machined aluminum body, hard-anodized finish and direct LED-board heat sinking support durability and thermal management.
IPX8 + Protected Electronics
Sealed/potted driver circuitry, battery protections and IPX8 waterproofing to 2 meters for 30 minutes support harsh-use reliability.
GTW TAKE

The Enthusiast Pick
The Zebralight H600c Mk IV earns its place through exceptional efficiency, beam quality, and long-term reliability. This is a headlamp built for users who care how light behaves and who are willing to learn the interface in exchange for control and performance. The neutral 4000K high CRI beam renders terrain and details accurately and stays useful for real work, not just quick brightness checks.
World-class electrical efficiency and thermal regulation
High CRI 4000K beam provides excellent color accuracy for reading terrain and close-in tasks
Durable construction with a strong reputation among experienced users
Tradeoff: Steep learning curve for the programming interface
