Length	111.5 mm
Body diameter	23.8 mm
Head diameter	24.5 mm
Material	aluminium alloy with HAIII hard-anodized finish
Colors	black

The 61.9 g flashlight may not provide the same level of brightness or features as larger models, it can be handy for quick and convenient illumination in emergency situations or for close-range tasks. 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. HAIII coating is widely used in the flashlight industry due to its durability, corrosion resistance, improved grip, and aesthetic appeal. This flashlight features a captivating black color.

System

Emitter	Cree XHP35 HD LED
Color temperature	6500 K
Reflector	SMO
Lens	toughtened AR coated glass
Switch	electronic side

Cree is widely regarded as a reputable LED manufacturer and has a track record of delivering high-quality and innovative lighting solutions. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The Concept 1 features a smooth reflector (SMO). If long-range illumination and throw distance are the primary requirements, a flashlight with a smooth reflector may be more suitable.

The AR coating on the lens maximizes light transmission, making the flashlight more effective in darker environments. The Concept 1 has electronic switch. The electronic switches may have a higher likelihood of standby drain compared to mechanical switches since they require a small amount of power for operation.

Performance

Flux	1800 lm
Intensity	12100 cd
Throw	220 m
CD/LM factor	6.72

The 1800 lm output of Concept 1 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. The Concept 1 flashlight with 12100 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	5 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 Concept 1 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 strobe function on the Concept 1 flashlight is a feature that produces a rapid and repetitive flashing of light. It is designed to create a disorienting or attention-grabbing effect. The Concept 1 has an SOS signal mode. The SOS code consists of three short signals, followed by three long signals, and then three short signals again.

The power source of the Concept 1 flashlight is 1 x 18650 Li-Ion battery, providing reliable and long-lasting energy for optimal performance. The Concept 1 doesn't have charger port. A charger port is a designated connection point or interface where you can plug in a charger to recharge the flashlight's battery. When the Concept 1 flashlight detects that the voltage of the battery has dropped to a certain threshold, it automatically reduces or cuts off the power output to prevent further discharge. This helps to preserve the battery's capacity and prevent it from reaching a critically low voltage level.

The Concept 1 has thermal protection feature. The thermal protection mechanisms are designed to monitor and regulate the temperature of the flashlight during operation. This feature helps prevent overheating, which can be detrimental to the flashlight's performance, battery, and overall safety. The Concept 1 flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer.

The Concept 1 flashlight proudly boasts an exceptional impact resistance rating of 1 m. The Concept 1 flashlight effortlessly clings to metal surfaces, granting you the freedom to go hands-free and explore versatile mounting possibilities.
