Acebeam K30 GT (K30GT) specifications

NameK30 GT
Rated 4/5 based on 1132 user votes.

The K30 GT flashlight offers precise and focused illumination. Unlike ambient or overhead lighting sources, flashlights allow you to direct the light exactly where you need it.


Weight336 g
Length155.5 mm
Body diameter44.5 mm
Head diameter57 mm
Materialaluminium alloy with HAIII hard-anodized finish

This 336 g flashlight would be considered relatively heavy for a handheld flashlight. Flashlights in this weight range may have features like extended battery life, intense brightness, or rugged construction for heavy-duty use. The length of a flashlight can also impact its balance and weight distribution. A well-balanced flashlight, where the weight is evenly distributed, can be more comfortable to hold for longer periods and reduce hand fatigue.

The aluminium body of K30 GT has excellent thermal conductivity, meaning it can effectively dissipate heat generated by the flashlight's components, such as the LED or battery. The HAIII process produces a hard and wear-resistant surface on the aluminum, making it more resistant to scratches, abrasions, and impacts. This improves the overall durability of the flashlight body. The K30 GT flashlight is offered in a stylish black color.

Luminus has established a positive reputation as a reliable LED manufacturer, and their products are widely used and trusted by lighting professionals and enthusiasts alike. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The primary function of the smooth reflector (SMO) is to precisely focus and project the light emitted from the light source into a defined beam pattern. The smooth surface allows for greater reflectivity and light concentration, resulting in a more focused and intense beam with a longer throw distance.

The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. This can increase the overall brightness and efficiency of the K30 GT flashlight. The K30 GT has electronic switch. The electronic switches may have a higher likelihood of standby drain compared to mechanical switches since they require a small amount of power for operation.


Flux5500 lm
Intensity262144 cd
Throw1024 m
CD/LM factor47.66

With 5500 lm, the K30 GT flashlight will provide an exceptionally bright and powerful beam of light. It can illuminate large areas, outdoor spaces, or even act as a temporary spotlight in certain situations. The K30 GT is a 262144 cd flashlight. Flashlights with extremely high luminous intensity often require significant power and generate more heat due to the increased energy output. The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. Candela per lumen (cd/lm) is a measure of a flashlight's beam intensity relative to its total luminous flux or output. It quantifies the concentration of light emitted by the flashlight in relation to the total amount of light produced.


Modes5 modes

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The K30 GT 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 strobe function on the K30 GT flashlight is a feature that produces a rapid and repetitive flashing of light. It is designed to create a disorienting or attention-grabbing effect.

The power source of the K30 GT flashlight is 3 x 18650 Li-Ion batteries, providing reliable and long-lasting energy for optimal performance. Having a battery indicator on a flashlight is beneficial as it allows users to monitor the battery status and make informed decisions regarding recharging or replacing the battery. It helps prevent unexpected power failures during critical situations and ensures that the flashlight is ready for use when needed.

The K30 GT cannot charge batteries directly. You may need an external charger to keep your battery going. When the K30 GT flashlight detects that the voltage of the battery has dropped to a certain threshold, it automatically reduces or cuts off the power output to prevent further discharge. This helps to preserve the battery's capacity and prevent it from reaching a critically low voltage level. The built-in thermal control automatically adjusts brightness output to prevent overheating.

The "6" in the IP68 rating represents the level of protection against solid objects, specifically dust and foreign particles. It indicates that the K30 GT flashlight, is fully protected against the entry of dust and other solid objects. The "8" in the IP68 rating indicates the highest level of protection against water ingress.


Package contents2 x spare o-rings

When gripping the flashlight with the lanyard around your wrist, it provides a more secure and stable hold. Instead of searching for compatible O-rings or waiting for replacements to arrive, having spare O-rings readily available allows for convenient and immediate repairs or replacements.

The performance of the Acebeam K30 GT 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.

The specifications above are based on the official data published by the manufacturer, but we also take user reviews into consideration. If you found an error or something lacking in the specifications above for the Acebeam K30 GT, then don’t hesite and signal the problem to us.
