This 275 g flashlight is not very heavy. But, it is heavier than the average handheld flashlight. The best flashlight size depends on personal preference. It also depends on intended use and the specific features you want. 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 comes in many colors. The choice of color can serve different purposes and preferences.

System

EmitterLuminus SST40 LED
Color temperature5000 K, 6500 K
ReflectorSMO
LensAR coated glass
Switchmechanical rear, reverse clicky

People know Luminus LEDs for their efficiency, brightness, color accuracy, and long lifespan. The color temperature choice depends on the light's use and personal taste. The M21C SST40 uses a smooth reflector. A smooth reflector is different from an orange peel reflector. It has a polished, mirror-like surface. The AR coating of the lens helps to reduce these reflections. It does this by changing the lens surface's refractive index.

The M21C SST40 uses multiple switches. The switches' placement and design determine this. They allow for one-handed operation. Mechanical switches often offer tactile feedback. Users can feel a distinct click or resistance when they press the switch. The rear switch of the M21C SST40 is usually operated with the thumb or finger. This makes it easy to reach and use.

The M21C SST40 flashlight utilizes 1 x 21700 Li-Ion battery as its power source. The M21C SST40 doesn't have charger port. LVP (Low Voltage Protection) is designed to protect the battery. It stops over-discharging, which can reduce battery life or cause permanent damage. The M21C SST40 has thermal protection feature. These mechanisms track and regulate the flashlight's temperature as it operates.

Accessories

Package contents2 x spare o-ring

Instead of searching for matching O-rings, having spare O-rings allows quick fixes.

According to the ANSI/NEMA FL1 Standard, we measure the performance of the Convoy M21C SST40 flashlight 30 seconds after switching on the light. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
