This 170 g flashlight would be considered slightly heavier than average for a handheld flashlight, but it is still within a reasonable weight range. This weight range is often found in smaller and more compact flashlights designed for everyday use or portability. It's important to consider the length of the flashlight to ensure it fits comfortably in your desired carrying method. The aluminium bodies can be anodized, providing a protective layer and a wide range of color options for flashlight bodies. Anodizing enhances the corrosion resistance, hardness, and scratch resistance of the aluminum, while also allowing for a variety of attractive finishes.

The HAIII coating provides excellent corrosion resistance, protecting the underlying aluminum from exposure to moisture, humidity, and other corrosive elements. It helps maintain the appearance and functionality of the flashlight, even in harsh environments. This flashlight features a captivating desert tan color.

The emitter of PT18 Pro Oathkeeper manufactured by Cree, a US-based LED manufacturing company. Cree is a well-regarded LED manufacturer known for its high-quality products and innovation in the lighting industry. Color temperature is a characteristic of light. It is measured in units called Kelvin (K) and is used to quantify the color appearance of light sources, particularly white light. The smooth reflector is typically used in flashlights where long-range illumination is a priority, such as searchlights or thrower flashlights. By minimizing light scattering and maximizing light directionality, the smooth reflector can produce a tighter and more concentrated beam that reaches greater distances.

The AR coating on the lens maximizes light transmission, making the flashlight more effective in darker environments. The PT18 Pro Oathkeeper uses multiple switches. Depending on the placement and design of the switches, a multiple switch configuration can allow for one-handed operation. This is particularly helpful in situations where you need to hold or manipulate objects with one hand while using the flashlight with the other hand.

The PT18 Pro Oathkeeper utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches. The PT18 Pro Oathkeeper uses a reear switch. Rear switches are commonly found on tactical flashlights designed for law enforcement, military, and self-defense purposes. The rear switch allows for quick and easy momentary activation or constant-on activation, enabling rapid response and tactical maneuvering.

CD/LM factor16

The 2000 lm output of PT18 Pro Oathkeeper provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. The PT18 Pro Oathkeeper flashlight with 32000 cd has an extended throw distance, allowing you to illuminate objects or areas at greater distances. This can be advantageous for outdoor activities, search and rescue operations, or scenarios where long-range visibility is required.

The throw distance refers to the maximum distance at which the flashlight can effectively illuminate an object or target. The stated throw distance typically indicates the point at which the brightness falls below a specified threshold, such as 0.25 lux. Flashlights with a higher cd/lm ratio typically excel in long-range throw and focused beam applications, while flashlights with a lower cd/lm ratio may provide a wider and more evenly distributed beam for closer-range illumination or general-purpose use.


Modes4 modes
Mode memoryyes
Ramping modeno

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The PT18 Pro Oathkeeper has mode memory.
