The S21A is small, compact, and designed for ultra-portability. A smaller flashlight is easier to carry in a pocket, bag, or pouch. This makes it more convenient for everyday use or when you're on the go. The aluminium body of the S21A 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. Factors can influence the color choice of the flashlight body. These include intended use, environment, personal style, and requirements.

Luminus has established a positive reputation as a reliable LED manufacturer. Warm, white light is generally more comfortable. It's also less harsh on the eyes than cool, white light. The designers of the S21A incorporated an orange peel reflector to enhance the beam. It does this by diffusing the light from the light source. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens.
Mechanical switches are usually robust. They resist wear and tear and work in many environments. The rear switch is at the end of the S21A flashlight. It helps you hold it securely.
Performance, flux, intensity, throw
Flux | 2300 lm |
---|---|
Intensity | 19600 cd |
Throw | 280 m |
CD/LM factor | 8.52 |
With 2300 lm, the S21A flashlight will offer a brighter and more powerful beam of light. The S21A flashlight has 19600 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. Candela per lumen (cd/lm) measures a flashlight's beam intensity. It compares this to its total luminous flux or output.
Software, user interface, modes
Modes | 4/12 modes |
---|---|
Mode memory | yes |
Ramping mode | no |
Strobe | yes |
SOS/Beacon | yes |
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. The S21A is tactical strobe ready. The strobe light is disorienting to the person it is aimed at, this makes it hard for them to concentrate. The SOS flashes Morse code so you can signal for help when needed.
Features, battery, protections

The S21A flashlight's power source is 1 x 21700 Li-Ion battery. It provides reliable, long-lasting energy for top performance. The S21A cannot charge batteries. You may need an external charger to keep your battery going. The flashlight detects when the battery's voltage has dropped to a certain level. Then, it reduces or cuts off the power. The thermal protection feature helps prevent overheating. Overheating can harm the flashlight's performance, battery, and safety.
The "8" in the IPx8 rating means the highest level of protection. It is against water ingress. The flashlight's impact resistance is its ability to withstand physical shocks. It can accomplish this without sustaining any damage.
