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 TIR lens of TK16 AL SST20 consists of a single-piece lens made of a transparent material, typically acrylic or polycarbonate. Its shape and internal geometry are designed to achieve specific light distribution patterns, such as flood or spot beams, by manipulating the behavior of light rays.

The TK16 AL SST20 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 TK16 AL SST20 is designed to be rugged and durable, capable of withstanding harsh conditions and repeated use.

The 1250 lm output of TK16 AL SST20 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. With 3570 cd, the TK16 AL SST20 flashlight provides a noticeably brighter and more intense beam of light. It can illuminate objects or areas with greater clarity and visibility, even at longer distances. 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. In some cases, a flashlight with a higher CRI may offer a more natural and pleasant viewing experience, as it can better reveal the true colors of the surroundings. This can be advantageous when using a flashlight for extended periods or in situations where visual comfort is desired. With a CRI of 95, the TK16 AL SST20 flashlight can render colors with exceptional fidelity, capturing even subtle nuances and details in color. This makes it particularly well-suited for applications where precise color discrimination and accurate color reproduction are critical.


Modes5 modes

Ramping modeno

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The TK16 AL SST20 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. Strobe mode on TK16 AL SST20 flashlight produces a rapid, repeated flashing of light. It can be used for signaling purposes, self-defense, or attracting attention in emergency situations.

The TK16 AL SST20 flashlight utilizes 1 x 16340 Li-Ion battery as its power source. The TK16 AL SST20 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 TK16 AL SST20 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 TK16 AL SST20 flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer.


Package contents16340 battery
2 x spare o-rings
spare rubber cover

The included battery is selected by the manufacturer to ensure optimal compatibility and performance with the TK16 AL SST20 flashlight. When the flashlight is clipped to a suitable location, it can be angled or positioned to provide hands-free illumination. Regularly replacing worn or damaged O-rings helps maintain the overall durability and performance of the flashlight.

The performance of the Acebeam TK16 AL SST20 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.
