Both models share the same output specification — 650 lumens boost, IP67 protection, dual power source and 92g weight. The HF4R Pro is designed for professional trade and industrial use, including a helmet connecting kit and fixing clips for PPE-compliant hands-free deployment, and a red light for night vision in confined work environments. The HF4R RGB is aimed at outdoor enthusiasts, adding green and blue colour modes specifically for wildlife observation and waterside use, with a camouflage headband design. Choose the Pro for professional and site use; choose the RGB for outdoor pursuits.

The HF4R Pro includes a helmet connecting kit and fixing clips in the box, allowing it to be mounted directly to compatible safety helmets and hard hats for PPE-compliant hands-free use on site. The rubberised headband is also available as an alternative for use without a helmet. No additional accessories are required for standard helmet mounting.

Yes. The HF4R Pro features a dual power source — it runs on the included 1,350mAh rechargeable polymer battery, charged via USB-C in 210 minutes, and also accepts standard disposable batteries via the included Connect Adapter (HF 2026). This ensures you always have a power option available on site or in the field when recharging is not possible.

The HF4R Pro offers four output levels: Boost (650 lumens / 130m beam), Standard (400 lumens / 120m / 3hrs), Mid power (100 lumens / 60m / 10hrs) and Low power (20 lumens / 20m / 45hrs). For sustained professional use, Standard mode balances output and runtime effectively. Low power's 45-hour runtime provides a practical extended option for lower-demand tasks.

Red light preserves night vision — allowing you to illuminate your immediate working area without the eye adjustment required after white light exposure. In confined professional environments such as engine rooms, machinery compartments and poorly lit workspaces, red light also reduces harsh glare and is less disruptive to colleagues working nearby.

Yes. The HF4R Pro carries an IP67 rating, confirming full dust protection and water resistance to submersion up to 1 metre. Combined with a 1.5-metre drop test, it is built for the sustained outdoor and industrial exposure of professional site use across all weather conditions.
