This 426 g flashlight is quite heavy for a handheld flashlight. The increased weight can provide advantages such as longer runtime, enhanced durability, and the ability to project a brighter and farther-reaching beam. The length of a flashlight can affect how it feels in your hand and how you can grip and maneuver it. A longer flashlight may provide a more substantial grip, making it easier to hold and control, especially if you have larger hands.

The aluminium body of B400 has excellent thermal conductivity, meaning it can effectively dissipate heat generated by the flashlight's components, such as the LED or battery. The HAIII coating can also enhance the visual appearance of the flashlight. It offers a uniform and attractive finish, often available in different colors, giving the flashlight a sleek and professional look. The B400 flashlight is offered in a stylish black color.

Cree LEDs are commonly used in a wide range of lighting applications. Their products are trusted by lighting professionals and have gained a strong reputation for quality and performance. The choice of color temperature depends on the specific lighting application and personal preferences. With the smooth reflector of the B400, the beam tends to have a well-defined hotspot at the center, which provides a concentrated beam of light for long-range applications.

The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. This can increase the overall brightness and efficiency of the B400 flashlight. The B400 has electronic switch. Some flashlights with electronic switches have programmable features that allow users to customize the behavior of the flashlight. This may include setting specific modes, configuring brightness levels, or enabling unique functions according to individual preferences.

Throw346 m
CD/LM factor2.5

With 12000 lm, the B400 flashlight will provide an exceptionally intense and blindingly bright beam of light. It can illuminate large areas, vast outdoor spaces, or even serve as a temporary spotlight in the darkest conditions. The B400 flashlight with 30000 cd has an extended throw distance, allowing you to illuminate objects or areas at greater distances. This can be advantageous for outdoor activities, search and rescue operations, or scenarios where long-range visibility is required.

The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. Candela per lumen (cd/lm) is a measure of a flashlight's beam intensity relative to its total luminous flux or output. It quantifies the concentration of light emitted by the flashlight in relation to the total amount of light produced.


Modes6 modes
