Lumintop FW4A SST20 specifications

The FW4A SST20 flashlight enhances safety. It illuminates hazards and improves visibility in low light.

Body, materials, weight, colors

The flashlight weighs 63 g. It is lightweight and easy to handle for most people. A balanced flashlight has even weight. It can be more comfortable to hold for longer and reduce hand fatigue. The aluminium body of the FW4A SST20 has a reputation for being durable and strong. It offers excellent resistance to impacts, scratches, and corrosion. Flashlight makers widely use HAIII coating. It is durable, resists corrosion, and improves grip. It also looks good. Factors can influence the color choice of the flashlight body. These include intended use, environment, personal style, and requirements.

System, LED, lens, reflector

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 TIR lens makes the LED light collimated. It does this into efficient, well-controlled beams. These beams maximize the usable lumens in the target area. The electronic switches may have a higher chance of standby drain. The rear switch of the FW4A SST20 is rugged and durable. It can withstand harsh conditions and repeated use.

Performance, flux, intensity, throw

With 2100 lm, the FW4A SST20 flashlight will offer a brighter and more powerful beam of light. The FW4A SST20 flashlight has 5625 cd. It provides a much brighter and more intense beam. 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.

If accurate color is a priority for you, choose a flashlight with a CRI of 90 or above. A CRI of 95 indicates extremely high color accuracy. It provides a near-perfect representation of colors.

Software, user interface, modes

Anduril software offers many output modes. These include different brightness levels, strobe modes, beacon modes, and more. 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 FW4A SST20's ramping mode is easy to use. It lets you smoothly change the output over its whole range. The FW4A SST20 flashlight has a strobe function. It produces a rapid, repetitive flashing of light. The SOS signal is commonly used in outdoor adventures or survival scenarios.

Features, battery, protections

The FW4A SST20 flashlight's power source is 1 x 18650 Li-Ion battery. It provides reliable, long-lasting energy for top performance. The FW4A SST20 cannot charge batteries. You may need an external charger to keep your battery going. This flashlight has built-in low voltage protection (LVP). It prevents damage from over-discharge, so it doesn't need protected cells. 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.

Accessories, package contents

The clip is very helpful. It lets you quickly access your flashlight while keeping your hands free for other tasks. When using spare O-rings, follow the maker's instructions. Use their guidelines for proper installation.

According to the ANSI/NEMA FL1 Standard, we measure the performance of the FW4A SST20 flashlight 30 seconds after switching on the light. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
