This 125 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. 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.

The emitter of S3 Pro HD 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 S3 Pro HD 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 S3 Pro HD utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches. The S3 Pro HD 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 S3 Pro HD 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 | 1600 lm |
---|---|
Intensity | 40804 cd |
Throw | 404 m |
CD/LM factor | 25.5 |
The 1600 lm output of S3 Pro HD provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. The S3 Pro HD flashlight with 40804 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 | yes |
Ramping mode | no |
Strobe | yes |
SOS/Beacon | yes |
Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The S3 Pro HD has mode memory. Mode memory means that the flashlight will remember the mode you were using when the light was last turned off, and when you turn it on again. The S3 Pro HD is tactical strobe ready. The strobe light is disorienting to the person it is aimed at which makes it difficult for them to concentrate. It has the SOS beacon function for an emergency situation. The SOS flashes Morse code so you can signal for help when needed. The SOS signal is recognized as an international distress call and is used to indicate an urgent need for assistance.
