This is an awesome headlamp and I have quite a few in my collection. I also own a Ledlenser MT10 flashlight and ML6 lantern, so I have some experience with their products. The HF6R feels very solid in the hand and gives off a feel of quality. It’s actually a bit on the heavy side but is still easily supported by the headband, of which there are 2 with the smaller one being removable. I believe this second strap is to facilitate with helmet mounting. I’m using the included silicone gel pad with the headband and find it comfortable to wear although I haven’t worn the light for prolonged periods of time. The headband is attached to a bracket that has a freely adjustable tilt rather than using pre-defined stops. The tilting mechanism is stable, feels strong and stays where you put it and the free rotation is something I didn’t appreciate until actually using it.There are 4 separate LEDs on this headlamp, each with their own reflector and lens.A single red LED for low-light/night vision preservation which looks to be your standard 5-10 lumen output and puts out a perfectly usable amount of light in a flood pattern. You can also jump directly to the red light mode from the off position by holding down the power button for a few seconds which is always a nice feature to have.Now, the 3 white LEDs and digital focus system: Large Flood, Small Flood and Spot Beam. At the bottom of the light, there is a small rotary dial that is the ‘digital’ focus. Rotating the wheel will use all 3 LEDs to dial in what type of lighting you need, ranging from just the Spot Beam for distance to only the Small Flood Light for personal tasks. Anywhere in between these two positions the light intelligently modulates between using all 3 white LEDs, brightening one, dimming another, turning one beam off and another on effectively creating a digital zoom system. The implementation here is excellent and so are the results, it works very well, and really is just plain cool to see in action. The focus dial also has a nice feel to it with no wobble and rotates smoothly so that’s another plus.There’s a single button on the top of the headlamp for all functions and it’s pretty simple to use. One click from off will take you to the last used brightness setting, continue clicking to cycle through the 3 settings of Low, Medium, High. It’s nice to see a memory function here for brightness and the light even remembers the digital focus setting. Excellent! A double-click while the light is on will activate Boost/Turbo mode for 30 seconds and then the light reverts back to whatever brightness it was at previously. A single click while the light is on will turn it off. Holding the button down for 3 seconds - whether the light is on or off - will switch to the Red Light mode.I haven’t had a chance to test the claimed battery life but Ledlenser’s numbers are usually accurate in my experience with their other products and they don’t play a bunch of games with runtime, light output or throttling. Everyone is doing the magnetic charging thing these days and it works fine here but I still prefer straight USB-C charging and maybe even a removable battery pack with the option to run off AAA batteries as well but none of these are dealbreakers for what is otherwise an excellent headlamp.
