If you mainly need a flashlight for basic tasks like finding keys, navigating in dimly lit areas, or occasional use around the house, 85 lm can be adequate. 170 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. 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.
Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. SOS mode of the Thumb produces a specific sequence of long and short flashes to signal distress or emergency situations. It is commonly used in outdoor adventures or survival scenarios.
|Battery||integrated Li-Ion battery|
|Impact resistance||1 m|
The Thumb flashlight utilizes integrated Li-Ion battery as its power source. The Thumb has a battery indicator. A battery indicator is a feature that provides information about the remaining power level of the flashlight's battery. It helps users monitor the battery status and estimate how much runtime they have left before the battery needs to be recharged or replaced. USB rechargeable flashlights have become increasingly popular in recent years due to their convenience and sustainability.
The Thumb flashlight doesn't have built-in LVP, it is recommended to use a protected battery to prevent over-discharging. The protective circuit of battery helps safeguard the battery from various potential risks and ensures safe and reliable operation. This flashlight doesn't have built-in temperature control. Flashlights without thermal protection may rely on other design elements for heat dissipation, such as heat sinks, fins, or body materials with good thermal conductivity.
The Thumb flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer. It is recommended to handle flashlights with care and avoid subjecting them to unnecessary rough treatment to ensure their longevity and reliable operation. Auxiliary LEDs with different color options or specialized modes can be beneficial for specific tasks.
