The 16.1 g flashlight would be considered extremely lightweight for a handheld flashlight. 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. Aluminium is a lightweight material, which is beneficial for GLOW I flashlight.

The HAIII process produces a hard and wear-resistant surface on the aluminum, making it more resistant to scratches, abrasions, and impacts. This improves the overall durability of the flashlight body. This flashlight comes in a sleek black color option.

Osram has a reputation for producing LEDs that deliver consistent quality and durability. Their products often undergo rigorous testing and adhere to industry standards to ensure high performance and longevity. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The TIR lens of GLOW I consists of a single-piece lens made of a transparent material, typically acrylic or polycarbonate. Its shape and internal geometry are designed to achieve specific light distribution patterns, such as flood or spot beams, by manipulating the behavior of light rays.

Performance

Flux	40 lm
Intensity	120 cd
Throw	22 m
CD/LM factor	3

If you mainly need a flashlight for basic tasks like finding keys, navigating in dimly lit areas, or occasional use around the house, 40 lm can be adequate. 120 cd can provide a reasonable level of luminous intensity for many everyday lighting tasks. 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. The candela per lumen (cd/lm) ratio can be used to determine if a flashlight has a spot or flood type beam. Well-focused spot beams can be over 100 cd/lm, tactical flashlights are typically between 20-100 cd/lm, and work lights are less than 10 cd/lm.

The power source of the GLOW I flashlight is integrated 10180 Li-Ion battery, providing reliable and long-lasting energy for optimal performance. The GLOW I flashlight can be charged directly from a USB power source, such as a wall adapter, computer, power bank, or car charger. This allows for convenient and versatile charging options, as you can utilize various USB power sources to recharge the flashlight's internal battery.

When the GLOW I 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. Flashlights without thermal protection may be more susceptible to overheating under extreme conditions, such as prolonged high-output use or exposure to high ambient temperatures.

The "6" in the IP68 rating represents the level of protection against solid objects, specifically dust and foreign particles. It indicates that the GLOW I flashlight, is fully protected against the entry of dust and other solid objects. The GLOW I flashlight with IP68 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer. The GLOW I flashlight effortlessly clings to metal surfaces, granting you the freedom to go hands-free and explore versatile mounting possibilities.
