The A01 is small, compact, and designed for ultra-portability. Consider the length of the flashlight. It should fit comfortably in your chosen way to carry it. The aluminium body of the A01 has excellent thermal conductivity. This means it can effectively dissipate heat generated by the flashlight's components. Flashlight makers widely use HAIII coating. It is durable, resists corrosion, and improves grip. It also looks good. Factors can influence the color choice of the flashlight body. These include intended use, environment, personal style, and requirements.

Their exceptional color quality is a well-known characteristic of Nichia LEDs. They are also known for their high efficiency and long lifespan. Warm, white light is generally more comfortable. It's also less harsh on the eyes than cool, white light. The designers of the A01 incorporated an orange peel reflector to enhance the beam. It does this by diffusing the light from the light source.

Throw37 m
CD/LM factor3.33

102 lm can provide a decent amount of brightness and be suitable for many everyday tasks. 340 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. If accurate color is a priority for you, choose a flashlight with a CRI of 90 or above. The A01 flashlight has a CRI of 90. It provides true-to-life colors. This makes it ideal for tasks where accurate color discrimination is crucial.

The A01 flashlight's power source is 1 x AAA battery. It provides reliable, long-lasting energy for top performance. The A01 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). Flashlights without thermal protection may rely on other design elements to dissipate heat. These elements include heat sinks, fins, or body materials with good thermal conductivity. The "8" in the IPx8 rating means the highest level of protection. It is against water ingress.
