The TK25 is generally comfortable to hold for a long time. It is also easy to carry in pockets or bags. Consider the length of the flashlight. It should fit comfortably in your chosen way to carry it. Aluminium is a lightweight material, which is beneficial for TK25 flashlight. HAIII is a specific anodizing process. It creates a thicker and harder oxide layer than regular anodizing. This flashlight comes in a sleek black color option.

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. If you need long-range light, get a flashlight with a smooth reflector. It will have more throw distance. The AR coating of the lens helps to reduce these reflections. It does this by changing the lens surface's refractive index. The TK25 uses multiple switches. The switches' placement and design determine this. They allow for one-handed operation.

The electronic switches may have a higher chance of standby drain. Mechanical switches often offer tactile feedback. Users can feel a distinct click or resistance when they press the switch. Rear switches are common on tactical flashlights. Law enforcement, military, and self-defense personnel use them.

The 1060 lm output of TK25 provides great flexibility. You can adjust the brightness to fit different needs. The TK25 flashlight has 13600 cd. It can light objects at greater distances. 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.

LVP (Low Voltage Protection) is designed to protect the battery. It stops over-discharging, which can reduce battery life or cause permanent damage.

This flashlight doesn't have built-in temperature control. The flashlight has an IPx8 rating. It can withstand being submerged in water beyond 1 meter for a prolonged period. The manufacturer specifies this.
