Materialaluminium alloy with HAIII hard-anodized finish

The Perun is small, compact, and designed for ultra-portability. It's important to consider the length of the flashlight to ensure it fits comfortably in your desired carrying method. The aluminium body of Perun has excellent thermal conductivity, meaning it can effectively dissipate heat generated by the flashlight's components, such as the LED or battery. HAIII coating is widely used in the flashlight industry due to its durability, corrosion resistance, improved grip, and aesthetic appeal. The choice of flashlight body color can be influenced by factors such as intended use, environment, personal style, and functional requirements.

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 TIR lens of Perun can minimize light loss and achieve high light output by capturing and redirecting a significant portion of the emitted light. This can result in improved overall beam quality, better beam control, and reduced stray light. The Perun 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.

With 2000 lm, the Perun flashlight will offer a brighter and more powerful beam of light. This higher output can be advantageous in various situations where you require enhanced visibility or need to illuminate larger areas. With 3600 cd, the Perun flashlight provides a noticeably brighter and more intense beam of light. It can illuminate objects or areas with greater clarity and visibility, even at longer distances.

The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. Candela per lumen (cd/lm) is a measure of a flashlight's beam intensity relative to its total luminous flux or output. It quantifies the concentration of light emitted by the flashlight in relation to the total amount of light produced.

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The Perun 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 Perun 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 Perun flashlight is 1 x special 18650 Li-Ion battery, providing reliable and long-lasting energy for optimal performance. Having a battery indicator on a flashlight is beneficial as it allows users to monitor the battery status and make informed decisions regarding recharging or replacing the battery. It helps prevent unexpected power failures during critical situations and ensures that the flashlight is ready for use when needed.

The USB charger port on a flashlight can be particularly useful in emergency situations where access to power outlets may be limited. A protected battery is recommended as the light itself does not have low voltage protection (LVP). The built-in thermal control automatically adjusts brightness output to prevent overheating. The "8" in the IPx8 rating indicates the highest level of protection against water ingress. This feature can be especially useful in situations where you need a stable and directed light source while keeping your hands available for work or other activities.

By including a battery with the flashlight, you avoid the additional expense of purchasing a battery separately. The clip allows you to attach this flashlight to a belt, pocket, backpack, or other items, enabling convenient hands-free carry. This is especially helpful when you need quick access to your flashlight while keeping your hands available for other tasks. Attaching a lanyard to your Perun flashlight provides an additional layer of security, reducing the risk of accidental drops or loss.

The performance of the Olight Perun flashlight is measured according to the ANSI / NEMA FL1 Standard 30 seconds after switching the light on. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
