I love watching the sunrise and the sunset, and often move in the dark. Headlamps are essential for working in the dark. This time we will introduce the HF6R Core headlight from LERLENSER, a German-born portable light brand.
Headlamps are not all about LM (lumens), which represent brightness, but are equipped with the manufacturer's unique technology, which is packed with incredible light and irradiation distance to ensure that they are firmly illuminated in the dark night.
In this article, we will tell you about the appeal of the LEDLENSER HF6R Core, which is not just based on the specs, but is only understood by the use of it.

Detailed review
We will tell you about the actual tests we have done in the Northern Alps and Okuchichibu mountains.
Powerful light volume up to 800lm
The headlamp I used was about 300lm. I felt it was pretty bright when using the 500lm headlamps, but the HF6R Core offers up to 800 lumens of brightness, making it an order of magnitude more secure when walking in the dark.
Bright headlamps in the dark are nothing more than justice (though this is based on the experience, when illuminated with maximum light, I was able to understand the situation of the trail at a level that is no different from that during the day)
High light levels allowed us to grasp the road conditions clearly.
It will be useful for those who are planning to take action before dawn or after sunset, or for speedy activities such as trail running.
Comes with a red mode, so you can use it when taking photos or tents.
You can switch to red mode by pressing the button for the HF6R Core. It is etiquette to use the red mode to avoid blinding at tents where people are crowded or at photo points.
I also take pictures of starry sky, so it is a must-have for the headlamp to have a red mode.
It can keep high light for a long time
In the unique measurement of irradiation time and light intensity (see table below), when the power mode output is continuously turned on, it is possible to maintain high light intensity for about 3 hours (the first headlamp tested by Outdoor Gearzine, the HF6R Core has maintained this amount of light intensity for a long time, for as long as three hours).
The brightness (in units of lux) measured every 10 seconds using an illuminator installed on a wall about 1m from the light source. The output is power.
The measurements are not made using a test institution or other means, so this is not a strict result, but the position of the headlamp is not moving during measurement, so there is some reproducibility of changes in the amount of light.
the HF6R Core is a recommended headlamp for those who want to keep the light on for a long time with high light
Focus function that allows you to change the illumination range if necessary
This focus function is my favorite feature. You can change the illumination range by turning the wheel. This function allows you to easily change the illumination range according to the situation, allowing you to respond quickly when you want to illuminate wider or pinpoint illuminate.
The "800 lumens" light amount is a punchy amount at first glance, but whether this high light amount is concentrated or diffused will greatly change what you feel when illuminated, and your preferences will also vary. For example, when you act at a fast pace, you can illuminate the distance and check the situation, but if you don't know exactly what to do next, you will be scared to be able to speed up the way you want.
Conversely, if you act at a slow speed, you can feel more secure by illuminating your surroundings evenly rather than illuminating the distance.
Adjustable by turning the wheel
With this focus function, anyone can use it without choosing the scene, from climbing to trail running.
A two-sided headband with a high fit
The illumination power, brightness, and color are important when choosing a headlamp, but whether it is comfortable to wear is also a key point when choosing a headlamp.
You don't have to worry about it if you're just going from the tent to the toilet, but if you're going before dawn, you may be wearing it for a few hours, so the feeling of holding, pressure, and weight become important.
The HF6R Core has a forked headband that provides high hold. In addition, the two-way headbands have a length that can be adjusted for each, so they can fit the user's head size and provide a higher hold.
There was rarely any shift when walking, and I didn't feel any shift when I ran.
The weight of 126g can be felt when you move for a long time.
The high irradiation power and hold are the advantages of the HF6R Core, but what caught my eye when wearing it for a long time was the weight.
For me, who normally uses a headlamp of about 100g, the HF6R Core, which is 26g heavy, felt even more sluggish than its weight.
The HF6R Core weighs 126g, so considering its functionality and irradiation power, it is by no means a heavy headlamp, but if you are planning to operate for a long time, you should also consider the lightness of the headlamp.
Although the headband has high hold power, it supports the body weighing 126g, making it feel oppressive. If you are doing things for a short period of time, you won't be too concerned about tightening, but if you are doing things for a long period of time, you will find this feeling of pressure a little bit of concern.
It's a high fit, but I want a cushion on the back of the body
What caught my eye while I was on the back of the main unit, on the part that came into contact with my forehead, was missing a cushion or pad that absorbs sweat, so I felt a little uncomfortable when I was sweating as I continued to do so for a long time.
This discomfort can be eliminated by attaching the headlamp on top of a cap or something similar, rather than directly on your head. However, caps with brims block the headlights light, so taking measures depending on the situation, such as putting the brim back in place when in use.
Stepless angle adjustment possible
The HF6R Core can be adjusted steplessly within the range of motion, allowing users to adjust the angle to the best option.
I'm concerned that if the headlamp is adjustable in a stepless way, the angle will change while you are acting, but the HF6R Core never changes the angle due to vibrations or other factors while you are acting.
The HF6R Core can be adjusted in a stepless manner, but I was a little concerned that it cannot be adjusted upward.
It's not a concern when worn on my head, but I sometimes use the headlamp around my neck when relaxing at tents. In such cases, it would be nice if you could adjust the angle upwards.
When using the switch, place it downwards, and when you put it around your neck, you can adjust it upwards by hanging it around your neck, allowing you to illuminate your hands without having to wear it on your head.
An indicator that shows the remaining battery level at a glance
The built-in battery allows you to check the remaining battery level at a glance using an indicator. The biggest problem with battery-powered headlights is that you don't know the remaining battery level (I think this is by far the best).
Next, it seems like the hassle and cost of buying a battery.
HF6R Core relieves this stress. You can tell the remaining amount so you don't have to worry before you leave, and you can just charge it even if you don't have the battery on hand. There is no need to increase the amount of batteries left in your home, which is half-hearted.
Cannot be used in conjunction with batteries
The thing I'm worried about when the battery is having problems with the built-in battery headlights. Headlamp breakdowns can sometimes lead to inability to take action, so you should consider taking measures to prevent problems.
Headlamps that can be used in conjunction with batteries can be changed to batteries if there is a problem with the battery, and the advantage is that batteries are easier to obtain when walking on long-term trails.
Although the battery is not clear on the remaining capacity, considering the backup and ease of obtaining problems, there are some headlamps that can be used with both batteries and batteries.
Unreusable magnetic charger
The magnetic charging terminal can be connected with one touch, making it easy, but only a dedicated cable can be used.
The HF6R Core is charged using a dedicated magnetic cord. The advantage of magnetic systems is that they can be connected with just one touch, but no dedicated cords can be used to charge the device.
Nowadays, smartphones are popular, mobile batteries are essential items. You can charge it with a mobile battery, but since you cannot use your smartphone's charging cable to charge the HF6R Core, you will have one more thing to bring.
This is a concern for those who want to walk lightly with fewer equipment points.
The highest level of waterproof and dustproof
Headlamps can be used in bad weather, so they must not break even in harsh environments. It is also resistant to impacts, but the important thing is waterproof and dustproof.
The HF6R Core's dustproof and waterproof level is IP68, the highest level of IP standard, and it has a perfect dustproof level, completely protects dust from entering, and is waterproof enough to be used under the surface, making it perfect for durability.
Summary: You can freely adjust the brightness to the illumination range yourself. A comfortable, stress-free headlamp
Headlamps are essential items and can be considered lifelines for those who act in the dark. This gear can potentially divide your fate in the unlikely event.
Especially when you are looking for speed, the HF6R Core can be used to adjust long and short distances to the best irradiation depending on the situation.
Headlamps like the HF6R Core can be used for a variety of purposes in outdoor activities, making them versatile headlamps that can be used by anyone.
Put your headlamp on your head and head out looking for a spectacular view!
