The T4K is small, compact, and designed for ultra-portability. The best flashlight size depends on personal preference. It also depends on intended use and the specific features you want. The aluminium body of the T4K has excellent thermal conductivity. This means it can effectively dissipate heat generated by the flashlight's components. The HAIII coating resists corrosion well. It shields the aluminum from moisture, humidity, and other corrosive elements. Factors can influence the color choice of the flashlight body. These include intended use, environment, personal style, and requirements.

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 TIR lens of the T4K can reduce light loss. To achieve high light output, it captures and redirects much of the emitted light. The electronic switches may have a higher chance of standby drain.
