If this sounds like the type of headlamp you are looking for, look no further than the Thrunite TH20. Thrunite has long manufactured high quality lights that provide you with a great value for your money and the Thrunite TH20 doesn’t disappoint. This affordable headlamp includes many high end options that you find on the more expensive lights.

Before You Buy

If you have started looking at head lamps you are probably a little bit overwhelmed at the sheer number of choices. Before you make any kind of purchase you really need to stop and think about what you are buying. You need to ask yourself what kind of head lamp you are looking for. You need to determine ahead of time what features you want in a head lamp and what you plan to use the head lamp for. Most people want a head lamp that they can rely on, which the Thrnuite TH20 fits that bill perfectly. This well-built light comes from a long line of high quality lights from a very well known brand. As a head lamp you need something that will work in the outdoors, you want a hands free light that can light up even the darkest night and luckily the Thrunite TH20 meets those needs and more.

Thrunite TH20 Neutral White

ThruNite TH20 520 Lumen Headlamp Flashlight - Lightweight Waterproof IPX-8 with CREE XP-L LED Headlamp for Indoor & Outdoor Hiking,Camping, Cycling - NW

The Thrunite TH20 is a high output head lamp at an affordable price. The Th20 features a CREE XP-L V6 LED that is paired with an orange peel reflector to provide a very balanced beam. The beam produced by this head lamp offers a great range for the outdoors, but also provides a flood beam for any indoor tasks. The Thrunite TH20 offers two models, the neutral white and the cool white. I prefer the neutral white model as it shows real colors under the light. Unlike other head lamps, the TH20 is not made from plastic instead it is constructed from aircraft grade aluminum. The aircraft grade aluminum construction enhances the durability of the light and allows for better heat dissipation, so users can use the highest setting longer.

The Thrunite TH20 can be powered by two styles of batteries, which lumen output and runtime will vary based on the battery used. As a powerful, yet portable head lamp the Thrunite TH20 is also light weight and water proof. The head lamp provides you with a scale brightness adjustment system, which allows you to pick your exact level of brightness based on the task at hand. The TH20 also offers a built-in SOS mode that can be quite useful in the outdoors or any dangerous situation.

Thrunite TH20 Features & Benefits

User Interface

TH20 Side View incon 2

Users will be pleased to discover that the Thrunite TH20 is pretty straight forward to use. Batteries can be installed by unscrewing the tail cap and inserting the preferred battery. Once battery is inserted screw tail cap back on. Turning the light on or off requires a single press of the tail cap switch. Modes are also changed via the tail cap switch. The tamping mode allows you to adjust the brightness level to the task at hand rather than using a predefined mode. No matter what mode you are in a double click will take you to Turbo mode with another double click taking you to SOS mode. Predefined modes can be accessed via a long press in between each mode.

Multiple Battery Options

The Thrunite TH20 can be powered by one of two kinds of batteries, the Li-ion 14500 battery or an AA alkaline battery. One of the great things about the AA alkaline battery is those batteries are easy to find, you won’t have to worry about hunting them down as they can be found in every store around. Another benefit to the AA alkaline battery is they are better suited for lights that are exposed to various temperature changes. The AA battery far outlasts the rechargeable and is my preferred choice of batteries for the head lamp I keep in my glove box. Battery choice also affects run time and lumen output. With the Li-ion 14500 battery you have a maximum output of 520 lumens for 37 minutes, while the AA has a maximum output of 250 lumens for 893 minutes.

Comfortable to wear

As a headlamp one of the most important features is being comfortable to wear. The Thrunite TH20 offers a soft rubber band to provide you with amazing comfort when wearing the light. In addition to wearing the light on your head, you can also wear it around hard hats, motorcycle helmets, bike helmets, and baseball caps. The light growing hot to the touch when worn and used in Turbo mode is a very real concern. The Th20 addresses this concern by constructing the body of the light from an aircraft grade aluminum that is designed to dissipate heat generated from the light evenly.

Social Proof

In reading through several reviews online I am happy to report that many others feel the same way I do about the Thrunite TH20. Majority of the reviews that I have read have talked about how the TH20 is an impressive light at an affordable price. Reviewers talk about how the light is well built and how comfortable it is to wear. What makes the light such an excellent choice is how it’s neutral white emitter and flood beam with the ramping brightness makes this light for a variety of tasks. The only issue with this light is the fact that it is on the heavy side, but what can you expect from a head lamp that doesn’t use a plastic housing?
