This 426 g flashlight is quite heavy for a handheld flashlight. The length of a flashlight can affect how it feels in your hand and how you can grip and maneuver it. The aluminium body of the B400 has excellent thermal conductivity. This means it can effectively dissipate heat generated by the flashlight's components. The HAIII coating is uniform and attractive. It is often available in different colors, giving the flashlight a sleek, pro look. The B400 flashlight comes in a stylish black color.

ReflectorSMO
Lenstoughtened AR coated glass
Switchelectronic side

Lighting professionals trust Cree LEDs. Cree LEDs have gained a strong reputation for quality and performance. The color temperature choice depends on the light's use and personal taste. The smooth reflector creates a well-defined hotspot at the center. This hotspot provides a concentrated beam for long-range use. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. Some flashlights with electronic switches have programmable features. They allow users to customize the behavior of the flashlight.

Performance, flux, intensity, throw

Flux12000 lm

The B400 flashlight has 12000 lm. It will beam an intense and blindingly bright light. The B400 flashlight has 30000 cd. It can light objects at greater distances. The throw is the distance in meters at which the flashlight produces a light intensity of 0.25 lux. The candela per lumen (cd/lm) ratio can be used to determine if a flashlight has a spot or flood type beam.

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. You can use Strobe for signaling purposes. It can also be used for self-defense or to attract attention in emergency situations. The B400's SOS mode produces a specific sequence of long and short flashes. It signals distress or emergency.

The B400 flashlight utilizes 4 x 18650 Li-Ion batteries as its power source. The battery indicator helps users check the battery status. It also estimates how much runtime they have left before recharging the battery. The flashlight detects when the battery's voltage has dropped to a certain level. Then, it reduces or cuts off the power. The B400 has thermal protection feature. These mechanisms track and regulate the flashlight's temperature as it operates.

The "6" in the IP67 rating shows the level of protection. It's against solid objects, like dust and foreign particles. The "7" in the IP67 rating shows that the flashlight can survive being submerged in water. It can withstand a certain depth for a limited time without getting damaged.
