The GREEN DEVIL Rechargeable Headlamp is a purpose-built accessory designed to attach securely to Mervex Vent series hard hats. A purpose-made headlight bracket keeps the light steady through active work, so you can focus on the task at hand without needing to hold a light source.
Experience clear visibility with multiple modes that adapt to changing conditions. The headlamp features High, Medium, Low, Strobe, and SOS settings, plus a tilt mechanism that lets you angle the beam up to 90 degrees. This flexibility helps you illuminate the exact area you’re working on, whether you’re crawling under a shelf or inspecting a conduit from eye level.
Designed for real-world use, the headlamp is rechargeable and built to endure outdoor and indoor conditions. Its IPX5 waterproof rating provides protection against water spray, making it suitable for work in rain or humid environments. The rugged construction aims to stay comfortable during long wear, delivering steady light when you need it most.
Beyond the helmet light, the package includes a headlamp bracket, an elastic headband, and a charging cable. When not wearing a hard hat, you can switch to the elastic band for activities like camping, cycling, reading, or evening runs. The built-in magnet also enables you to mount the light on metal surfaces as a portable work light when needed.
Q: Is this headlamp compatible with Mervex Vent hard hats?
A: Yes—the headlamp bracket securely mounts on Mervex Vent hard hats for hands-free illumination.
Q: What lighting options and features does the headlamp offer?
A: Five modes (High, Medium, Low, Strobe, SOS), motion sensing, 90° tilt, and rechargeable power.
