This 275 g flashlight is not excessively heavy, but it is noticeably heavier than the average weight for handheld flashlights. The ideal length of a flashlight depends on personal preference, intended use, and the specific features and functionality you're looking for. Aluminium is a lightweight material, which is beneficial for M21C SST40 flashlight. The body of M21C SST40 flashlight treated with a Type III hard-anodized, anti-abrasive finish. The M21C SST40 flashlight is available in a variety of colors, and the choice of color can serve different purposes and preferences.

Switchmechanical rear, reverse clicky

Luminus LEDs are known for their efficiency, brightness, color accuracy, and long lifespan. They offer a wide range of LED products with different characteristics to meet the diverse needs of the market. The choice of color temperature depends on the specific lighting application and personal preferences. The M21C SST40 uses a smooth reflector. Unlike the textured surface of an orange peel reflector, a smooth reflector has a polished, mirror-like surface.

The AR coating of the lens helps to mitigate these reflections by altering the refractive index of the lens surface. The M21C SST40 uses multiple switches. Depending on the placement and design of the switches, a multiple switch configuration can allow for one-handed operation. This is particularly helpful in situations where you need to hold or manipulate objects with one hand while using the flashlight with the other hand.

The M21C SST40 has mechanical switch. Mechanical switches often offer tactile feedback, allowing users to feel a distinct click or resistance when the switch is pressed. This feedback helps users confirm that the switch has been activated or deactivated, providing a reassuring sense of control and awareness. The rear switch of M21C SST40 is designed to be rugged and durable, capable of withstanding harsh conditions and repeated use.

Performance

Flux2300 lm
Intensity98000 cd
Throw626 m
CD/LM factor42.61

The 2300 lm output of M21C SST40 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. With 98000 cd, the flashlight will provide an intense and powerful beam of light that can illuminate objects or areas with exceptional brightness and clarity. 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.

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The M21C SST40 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 M21C SST40 flashlight utilizes 1 x 21700 Li-Ion battery as its power source. The M21C SST40 doesn't have charger port. A charger port is a designated connection point or interface where you can plug in a charger to recharge the flashlight's battery. LVP (Low Voltage Protection) is designed to protect the battery from being over-discharged, which can lead to reduced battery life or even permanent damage. The M21C SST40 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.

Accessories

Package contents2 x spare o-ring

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

The performance of the Convoy M21C SST40 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.
