This makes it more convenient for everyday use or when you're on the go. Aluminium is a lightweight material, which is beneficial for E1 flashlight. HAIII is a specific anodizing process.

Cree is widely regarded as a reputable LED manufacturer. Warm, white light is generally more comfortable. It's also less harsh on the eyes than cool, white light. The E1's TIR lens is made of a single piece of transparent material. This material is typically acrylic or polycarbonate. The electronic switches may have a higher chance of standby drain. Rear switches are common on tactical flashlights. Law enforcement, military, and self-defense personnel use them.

The 1000 lm output of E1 provides great flexibility. You can adjust the brightness to fit different needs. The E1 flashlight has 9025 cd. It provides a much brighter and more intense beam. The throw distance is the farthest distance the flashlight can light an object. Candela per lumen (cd/lm) measures a flashlight's beam intensity. It compares this to its total luminous flux or output.

A flashlight's modes are different output settings or brightness levels. They can be chosen to meet different needs and preferences. The flashlight has mode memory. It remembers the mode you were using when the light was last turned off. It stays in that mode when you turn it on again. The E1 is tactical strobe ready. The strobe light is disorienting to the person it is aimed at, this makes it hard for them to concentrate. The SOS flashes Morse code so you can signal for help when needed.
