The SR16 flashlight is a bit heavy, its weight is 1130 g. It's important to consider the intended use and personal comfort when choosing a flashlight of this weight. 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. Aluminium is a lightweight material, which is beneficial for SR16 flashlight.

The HAIII coating provides excellent corrosion resistance, protecting the underlying aluminum from exposure to moisture, humidity, and other corrosive elements. It helps maintain the appearance and functionality of the flashlight, even in harsh environments. This flashlight comes in a sleek black color option.

Cree is widely regarded as a reputable LED manufacturer and has a track record of delivering high-quality and innovative lighting solutions. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The SR16 features a smooth reflector (SMO). If long-range illumination and throw distance are the primary requirements, a flashlight with a smooth reflector may be more suitable.

The AR coating of the lens helps to mitigate these reflections by altering the refractive index of the lens surface. The SR16 has electronic switch. The electronic switches may have a higher likelihood of standby drain compared to mechanical switches since they require a small amount of power for operation.


Flux55000 lm
Intensity736000 cd
Throw1716 m
CD/LM factor13.38

With 55000 lm, the SR16 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 SR16 is a 736000 cd flashlight. Flashlights with extremely high luminous intensity often require significant power and generate more heat due to the increased energy output.

The throw distance refers to the maximum distance at which the flashlight can effectively illuminate an object or target. The stated throw distance typically indicates the point at which the brightness falls below a specified threshold, such as 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. Well-focused spot beams can be over 100 cd/lm, tactical flashlights are typically between 20-100 cd/lm, and work lights are less than 10 cd/lm.

The power source of the SR16 flashlight is 4 x integrated 21700 Li-Ion batteries, providing reliable and long-lasting energy for optimal performance. Having a battery indicator on a flashlight is beneficial as it allows users to monitor the battery status and make informed decisions regarding recharging or replacing the battery. It helps prevent unexpected power failures during critical situations and ensures that the flashlight is ready for use when needed.

When the SR16 flashlight detects that the voltage of the battery has dropped to a certain threshold, it automatically reduces or cuts off the power output to prevent further discharge. This helps to preserve the battery's capacity and prevent it from reaching a critically low voltage level. The SR16 has thermal protection feature. The thermal protection mechanisms are designed to monitor and regulate the temperature of the flashlight during operation. This feature helps prevent overheating, which can be detrimental to the flashlight's performance, battery, and overall safety.

The "5" in the IP56 rating represents the level of protection against solid objects, specifically dust and foreign particles. The IP56 rated flashlight is protected against dust ingress to a limited extent. The IP56 rating indicates that the SR16 flashlight has a protection against water jets. With an impressive impact resistance rating of 0.5 m, the SR16 flashlight is built to endure accidental drops or impacts, ensuring its resilience and dependable performance in demanding situations.


Package contents2 x spare o-rings
AC charger
L-shape screwdriver

Regularly replacing worn or damaged O-rings helps maintain the overall durability and performance of the flashlight.

The performance of the Imalent SR16 flashlight is measured according to the ANSI / NEMA FL1 Standard 30 seconds after switching the light on. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
