1. SLONIK Lumen Headlamp

The next product that caught my attention is the SLONIK 1000 lumen rechargeable headband. The light generated by this headlamp allows you to see up to 600 ft.

I find this product great for when you need high-distance visibility, such as hiking or skiing. In addition to extended light, the headlamp gets charged quite easily through a USB cable. You need not attach it with those heavy wires and adapters. So when you are going on a backpacking trip, you can easily carry it along with you.

Another great thing about this headlamp is that it does not require disassembly; just connect and recharge. In low mode, the headlamp can offer 8 hours of battery life, whereas, in the high mode, you will get approximately 3.5 hours of performance. You can set the light mode according to the duration for which it has to be used.

The headlamp is constructed using aero-grade aluminum alloy 6063 for extreme conditions. It is also dustproof and IPX8 waterproof, making it ideal for personal as well as industrial use. Whether camping, running, HVAC, construction, or garage work, etc., this tool is perfect for carrying around anywhere, anytime.

Additionally, there is an adjustable nylon headband, which offers a comfortable and snug fit. Flexibility is another thing I like about this headlamp as I can swivel it up and down to 90-degrees for an ideal angle and switch between different modes.

However, I felt like this industrial headlamp is not as durable as marketed. The problem is the plug on the unit. Constant plugging and unplugging may influence its performance.

2. 77 Outdoor 1200 Lumen Headlamp

This is a powerful product that leverages SST40 LED to offer an optimum power output of 1200 lumens. Such a high level of power generation is perfect for a wide range of outdoor as well as indoor activities.

The light works in five different modes that include one low, medium one, medium two, high, and turbo. These features imply that you can easily take the headlamp anywhere and use it for various purposes.

Additionally, this product is rechargeable and features a hidden USB port. I like the fact that this gives the headlamp an overall clean appearance. Also, the 18650 battery is included with the headlamp.

As I often work in harsh conditions, I value a robust headlamp like this one. It is made of aircraft-grade aluminum alloy case and the hard-anodized finish, adding to the durability.

It weighs merely 2.9 ounces, excluding the battery, which makes it quite a comfortable product to put on your head. Additionally, the headband is completely adjustable, so you can easily get a secure fit. This will also ensure that the band does not slip off your head once fitted.

Nevertheless, I feel like the product could have been better if the manufacturer had included features like an overhead strap, neutral LED tint, and a lower Min mode.
What We Like
  • Leverages SST40 LED for an optimum power output of 1200 lumens
  • Five different modes for various uses
  • Aircraft-grade aluminum alloy case and hard-anodized finish for added durability

The push button on this headlamp makes it a user-friendly product. The button is also capable of retaining light output memory at different modes. There is a one-handed adjustment that offers lumens ranging from 0.3 to 1050.

The manufacturer uses quality material to build the device as it appears strong and durable. Along with the use of aircraft-grade aluminum, the headlamp also comes with IPX7 waterproof certification.

Along with being used as a headlamp, the straps can be removed, and the device can be used as a handheld light. The durability, flexibility, and convenience of the product make it ideal to use in different outdoor and indoor activities.

After a while, I figure that this device can run for four days on low mode and 12 hours on medium mode. You will have no hassle in recharging the battery as it is charged with a standard USB cable. It can be charged entirely within 4 to 5 hours.

The only complaint with this product is the rubber strap, which holds the light. The material can feel a little tight, making me feel a little uncomfortable at first.

I’m impressed by its integrated ATR technology, which automatically adjusts the headlamp brightness. The function is activated when the temperature reaches 55-degree or above to protect from overheating.

Best of all, the headlamp features a rear safety light embedded behind the battery box. This is controlled by an individual button on the box itself. Plus, this torch has certification from CE/UL for its safety.

What is an 18650 Headlamp


The 18650 headlamp is a small flashlight that gets attached to your head and comes with a powerful 18650 lithium-ion battery. With this lightweight battery, these headlamps can provide over 1000 lumens of power. Therefore, you can easily carry these even on lengthy trips. These batteries are rechargeable, making them friendly for the environment.

Apart from lithium ion headlamp, you can also find numerous other types of headlamps in the market. However, they will not provide as many benefits as the 18650 battery light. Plus, their unreliableness can leave you hanging at any point in the trip. That is why it is recommended that you always take these powerful headlamps with you.

How Does It Work 

The 18650 headlamps are like any other lamp that can be fitted on your head. You have to wear it on your crown and turn the light on whenever needed. However, the number of lights, power output, amount of light, and other factors may differ in various headlamps. Along with these, some of the products come with multiple light settings. That means you can alter the brightness as per your requirement.

Usually, these lamps use the protected 18650 batteries. These batteries are rechargeable. Therefore, you will need to plug-in your headlamps whenever they run out of battery. For this, you will typically get a house wall charger. But some of the manufacturers also provide car chargers for ease of recharging. That is one of the major reasons why these batteries are advised. They can easily go a long way without causing any trouble to you.

Types of 18650 Headlamps


Almost all 18650 headlamps work in the same way. But they still can be differentiated based on their features. Some of these characteristics are:

Light Modes: The fundamental difference between different headlamps can be its light modes. Some of them offer to change the illumination for up to five different types. On the other hand, some provide single illumination. If you need the lamp for a specific use, you can go for a single mode. Else the multiple modes will always come handy.

Battery Life: Not all 18650 headlamps run for the same duration. The ones that have better battery lives usually stay usable for longer. However, with the changing light modes, this may also change. For example, a lamp may discharge early on the high-light mode than a constant illumination lamp. So you need to find the top-quality 18650 battery for headlamp.

Water Resistance: There are a few manufacturers who offer water-resistant products. You can easily use them everywhere, irrespective of the weather conditions.

Focus: The light on the headlamp may focus on one spot or scatter into a large space. This can be a significant difference in different types of headlamp.

Apart from these, the headlamps also vary in style. Some of them offer a strap over the head, while others have just one round strap around the crown. You need to check both your style and comfort before buying.

Why Do You Need an 18650 Headlamp

Let me provide you with some reasons where a 18650 headlamp will come handy to you:

Adventure Activities

From hiking to trekking to camping, a 18650 headlamp can always help you out. They do not only assist you in looking for the way ahead but also in spotting any dangers. So even if you want to go to the bathroom at midnight, you can easily go with the headlamp assistance. The light can be utilized for reading out the map as well. So, you will remain completely safe with this product.

Going Out In The Dark

Whether you need to buy some snacks and drinks or walk your dog, it can become challenging to walk in the dark. Plus, you can not hold a flashlight due to the stuff in your hands. That is why you will need a 18650 headlamp. You just have to wear it on your crown, and you are good to go. Now, you can get out of your house at any time without any worries.


If you are like me who likes to read right before going to bed, a 18650 headlamp will be a blessing for you. With this on your head, you no longer need to disturb others in the room. You can simply switch on its light while reading your book in peace. Once you get done with it, you can switch the light off and keep it on the nightstand.

Home Repair

While repairing different sections of your house, you sometimes need additional light. As both of your hands are busy fixing the damage, you can not hold a flashlight. Instead of any other hassle, you can simply put on the headlamp. It will provide you with the required assistance without creating problems for other members.

Other Uses

There can be several other purposes for which you can use a 18650 headlamp. For example, it can be used during fishing, trail running, working on cars, or playing. Basically, you can take advantage of the light whenever you need to go into the dark.

Buying Guide


In case you can not decide which 18650 headlights to buy, you can follow this simple guide. I have included some crucial points that you must check before purchasing. So you will not end up wasting your effort and money on the wrong product.

LED Output: The ideal output of the chosen lamp must be at least 500 lumens. Opting for anything less than that will not solve your purpose. But along with high power, the headlamp must have the setting to lower the illumination. Therefore, you will be able to utilize it for multiple cases, and firefighters also can use them.

Band Fit: The light’s headband must be comfortable to wear. Neither should it pinch you in the head, not should it be loose. Plus, the material of the band must be soft and comfortable to wear. Otherwise, you will not be able to wear them for longer hours.

Charging Options: The method of charging the light must be friendly. As you will be using it mostly in places where there will not be enough charging facilities, this point is important.

Durability: Your 18650 headlamp is something you will be relying on in times of need. Imagine if you are in the middle of a forest and the lamp breaks. You will be left in a dangerous situation. That is why you need to opt only for the durable materials of the lamp.

Price: When you are going for a reliable product, price does not matter much. But still, it is good to seek value for money options. These will ensure you are not spending too much on some unnecessary features of the lamp.

Weight: The headlamp should be light enough so that you can keep it on your head for longer hours. Else it will become uncomfortable, and you will have to remove it.

Weather Resistance: When you are out camping or hiking, you can not tell when the rains hit. Thus, the headlamp you choose must be resistant against all these weather factors.

Apart from these, you can check the headlamp style as well. It should match with your style and preferences. Only then will you get happy wearing it and you will use it more often.

Care and Maintenance

A few care and maintenance tips for your 18650 headlamps are:

Generally, it is recommended to drain the battery entirely and then only recharge it. But in this case, never let the batteries get completely discharged. You need to maintain some charge in it at the time of recharge.

While storing it, make sure it is not discharged. Also, you need to keep the product away from high temperatures or direct sunlight.

For recharging the battery, only use the provided charger. An incompatible charger can ruin the battery for you.

Use the specific mode according to the use. If you use the high illumination mode for all purposes, the lamp’s battery will get low every now and then. Thus, you can not use it for longer.

Are 26650 better than 18650?

Both 26650 and 18650 are lithium rechargeable batteries available in two types: Protected and unprotected. Therefore, when it comes to available choices, 26650 and 18650 are the same. To know which option is better, you’ll need to look at their capacity, durability, price, and range of applications.

26650 batteries can generate high voltage to supply power for high-drain devices more efficiently. Depending on the brand, the average capacity of a 26650 ranges between 4500 mAh to 6000 mAh. They are commonly used for toys, vape, and tactical flashlights. Hence, they are pricier compared to their 18560 counterparts.

Overall, the 26650 is naturally more durable than the 18650. Besides, given its energy capacity, it allows devices to have a longer runtime. However, while the 18650 may appear superior, the 18650 excels in other ways.

Firstly, 18650 is more ‘mature’ since it has undergone more improvements than the 26650. Secondly, it has a broader range of applications. Besides the lightweight 18650 headlamp models, these lithium-ion batteries are commonly used in laptops, electronics, and some electric cars!

Also, the 18650 is smaller than a 26650 battery. Though they can be interchangeable due to their current outputs, the 18650 case may not fit a 26650.

How long do 18650 headlamps last?

There is no straightforward answer to this question since the headlamp has various parts. This includes the LED light, wiring, case, straps, and buckles.

The LED flashlight can last 50,000 to 100,00 hours when well-maintained. FYI, 50,000 hours is equivalent to 5.7 years! That said, choosing the right casing for the right application matters a lot since this, too, can influence the lifespan.

Some budget 18650 flashlight models have alloy casings, while others are made of plastic. Alloy is more hard-wearing than plastic. Since it’s also waterproof, it can be a suitable material for designing a headlamp for shelling or camping.

However, in firefighting, polymer plastic casings are the way to go. Because alloy conducts heat, firefighters can burn their skin when wearing or holding a detachable headlamp. For the same reason, the alloy casing cannot protect the batteries against high heat.

At any rate, even the brightest 18650 flashlight and headlamps models with durable casing do not last long if stored in hot conditions or when they sit idly on your shelf. Likewise, overcharging can damage the batteries.
