The 13 g flashlight would be considered extremely lightweight for a handheld flashlight. It's important to consider the length of the flashlight to ensure it fits comfortably in your desired carrying method. Aluminium is a lightweight material, which is beneficial for I1R 2 EOS flashlight. The HAIII coating often has a matte or textured finish, which enhances grip and provides a comfortable feel in the hand. This can be particularly useful in situations where a secure grip on the flashlight is essential, such as in wet or slippery conditions. This flashlight offers a wide array of color options, allowing you to choose from a diverse range of hues to suit your personal style and preferences.

System

Emitter	CSP LED
Color temperature	4000 K
Reflector	TIR
Lens	TIR
Switch	twisty

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 TIR lens of I1R 2 EOS 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	150 lm
Intensity	400 cd
Throw	40 m
CD/LM factor	2.67

If you mainly need a flashlight for basic tasks like finding keys, navigating in dimly lit areas, or occasional use around the house, 150 lm can be adequate. 400 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.

Software

The Olight I1R 2 EOS flashlight is powered by integrated Li-Ion battery. The I1R 2 EOS 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. This flashlight has a built-in low voltage protection (LVP) to prevent damage to the cell from over-discharge, so protected cells are not necessary.

This light does not have temperature control feature. The I1R 2 EOS flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer.

Accessories

Package contents	key ring

The performance of the Olight I1R 2 EOS 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.
