The 6 g flashlight would be considered extremely lightweight for a handheld flashlight. The length of a flashlight can also impact its balance and weight distribution. A well-balanced flashlight, where the weight is evenly distributed, can be more comfortable to hold for longer periods and reduce hand fatigue. Aluminium is a lightweight material, which is beneficial for I5T EOS flashlight. The I5T EOS flashlight is available in a variety of colors, and the choice of color can serve different purposes and preferences.


EmitterOsram P9 LED
Color temperature6500 K
Switchmechanical rear

Osram LEDs are known for their high performance, energy efficiency, and reliability. They provide a range of options in terms of brightness, color temperature, color rendering, and beam characteristics to meet different lighting requirements. The choice of color temperature depends on the specific lighting application and personal preferences. The TIR lens of I5T 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.

The I5T EOS has mechanical switch. Mechanical switches often offer tactile feedback, allowing users to feel a distinct click or resistance when the switch is pressed. This feedback helps users confirm that the switch has been activated or deactivated, providing a reassuring sense of control and awareness. The placement of the rear switch at the end of the I5T EOS flashlight facilitates a secure forward grip. This grip allows for better control and handling of the flashlight, especially in situations where precision and stability are important.


Flux300 lm
Intensity910 cd
Throw60 m
CD/LM factor3.03

If you mainly need a flashlight for basic tasks like finding keys, navigating in dimly lit areas, or occasional use around the house, 300 lm can be adequate. 910 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 I5T EOS flashlight utilizes 1 x AA battery as its power source. The I5T EOS 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. The I5T EOS 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 I5T EOS flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer.


Package contentsAA battery

The included battery is selected by the manufacturer to ensure optimal compatibility and performance with the I5T EOS flashlight. The clip provides flexibility in how you carry your flashlight.

The performance of the Olight I5T 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.
