Body

Weight	108.1 g
Length	141 mm
Body diameter	25.4 mm
Head diameter	31.8 mm
Material	aluminium alloy with HAIII hard-anodized finish
Colors	black

The 108.1 g flashlight is generally comfortable to hold for extended periods and easy to carry in pockets or bags. They are suitable for various applications such as camping, hiking, or emergency situations. A 120-gram flashlight strikes a good balance between functionality, convenience, and weight. The length of a flashlight can affect how it feels in your hand and how you can grip and maneuver it. A longer flashlight may provide a more substantial grip, making it easier to hold and control, especially if you have larger hands.

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. Hard-Anodized Type III (HAIII) is a specific anodizing process that creates a thicker and harder oxide layer compared to regular anodizing. It involves subjecting the aluminum to a higher voltage and a sulfuric acid bath, resulting in a dense and durable coating. This flashlight features a captivating black color.

System

Emitter	Cree XP-L HI V3 LED
Color temperature	6500 K
Reflector	SMO
Lens	toughtened AR coated glass
Switch	mechanical rear, mode pedal rear

Cree LEDs are commonly used in a wide range of lighting applications. Their products are trusted by lighting professionals and have gained a strong reputation for quality and performance. The choice of color temperature depends on the specific lighting application and personal preferences. The R25 uses a smooth reflector. Unlike the textured surface of an orange peel reflector, a smooth reflector has a polished, mirror-like surface.

The AR coating on the lens maximizes light transmission, making the flashlight more effective in darker environments. The R25 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 R25 has mechanical switch. Mechanical switches often offer tactile feedback, allowing users to feel a distinct click or resistance when the switch is pressed. This feedback helps users confirm that the switch has been activated or deactivated, providing a reassuring sense of control and awareness. With a rear switch of R25 flashlight, the operation of the flashlight is often straightforward and easy to grasp. A simple press or click of the rear switch turns the flashlight on or off, eliminating the need for complex button combinations or multi-step processes.

Performance

Flux	800 lm
Intensity	25800 cd
Throw	321 m
CD/LM factor	32.25

The 800 lm output of R25 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. The R25 flashlight with 25800 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.

Software

Modes	4 modes
Mode memory	no
Ramping mode	no
Strobe	yes
SOS/Beacon	no

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. Strobe mode on R25 flashlight produces a rapid, repeated flashing of light. It can be used for signaling purposes, self-defense, or attracting attention in emergency situations.
