Imalent DM21C (DM21C) specifications

Rated 4/5 based on 1237 user votes.

This Imalent flashlight is designed to be compact and handheld, making it easy to carry and maneuver.


Weight75 g
Length122 mm
Body diameter26 mm
Head diameter26 mm
Materialaluminium alloy with HAIII hard-anodized finish

The 75 g flashlight may not provide the same level of brightness or features as larger models, it can be handy for quick and convenient illumination in emergency situations or for close-range tasks. It's important to consider the length of the flashlight to ensure it fits comfortably in your desired carrying method. The aluminium bodies can be anodized, providing a protective layer and a wide range of color options for flashlight bodies. Anodizing enhances the corrosion resistance, hardness, and scratch resistance of the aluminum, while also allowing for a variety of attractive finishes.

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 features a captivating black color.

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 DM21C 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 on the lens maximizes light transmission, making the flashlight more effective in darker environments. The DM21C 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. The DM21C uses a reear switch. Rear switches are commonly found on tactical flashlights designed for law enforcement, military, and self-defense purposes. The rear switch allows for quick and easy momentary activation or constant-on activation, enabling rapid response and tactical maneuvering.

Throw367 m
CD/LM factor16.82

The 2000 lm output of DM21C provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. The DM21C flashlight with 33630 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 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. Flashlights with a higher cd/lm ratio typically excel in long-range throw and focused beam applications, while flashlights with a lower cd/lm ratio may provide a wider and more evenly distributed beam for closer-range illumination or general-purpose use.


Modes5 modes

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The DM21C has mode memory. Mode memory means that the flashlight will remember the mode you were using when the light was last turned off, and when you turn it on again. The strobe function on the DM21C flashlight is a feature that produces a rapid and repetitive flashing of light. It is designed to create a disorienting or attention-grabbing effect.

The power source of the DM21C flashlight is 1 x 18650 Li-Ion battery, 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.

USB rechargeable flashlights have become increasingly popular in recent years due to their convenience and sustainability. When the DM21C 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 DM21C 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 DM21C flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer.


Package contents18650 battery
