The flashlight weighs 19.4 g. It is lightweight and easy to handle for most people. A smaller flashlight is easier to carry in a pocket, bag, or pouch. This makes it more convenient for everyday use or when you're on the go. The aluminium body of the I3E EOS has a reputation for being durable and strong. It offers excellent resistance to impacts, scratches, and corrosion. Factors can influence the color choice of the flashlight body. These include intended use, environment, personal style, and requirements.

Warm, white light is generally more comfortable. It's also less harsh on the eyes than cool, white light. The TIR lens makes the LED light collimated. It does this into efficient, well-controlled beams. These beams maximize the usable lumens in the target area.

CD/LM factor5.56

90 lm can provide a decent amount of brightness and be suitable for many everyday tasks. 500 cd can make things quite bright. It's enough for many everyday tasks. The throw is the distance in meters at which the flashlight produces a light intensity of 0.25 lux. Candela per lumen (cd/lm) measures a flashlight's beam intensity. It compares this to its total luminous flux or output.

The I3E EOS flashlight's power source is 1 x AAA battery. It provides reliable, long-lasting energy for top performance. The I3E EOS cannot charge batteries. You may need an external charger to keep your battery going. Use a protected battery. This flashlight lacks low voltage protection (LVP). This light does not have temperature control feature. The "8" in the IPx8 rating means the highest level of protection. It is against water ingress.

By including a battery with the flashlight, you avoid the extra expense. You would have to buy a battery separately.

According to the ANSI/NEMA FL1 Standard, we measure the performance of the I3E EOS flashlight 30 seconds after switching on the light. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
