Length200 mm
Body diameter60 mm
Head diameter100 mm
Materialaluminium alloy with HAIII hard-anodized finish

The HK90 flashlight is a bit heavy, its weight is 1119 g. It's important to consider the intended use and personal comfort when choosing a flashlight of this weight. The ideal length of a flashlight depends on personal preference, intended use, and the specific features and functionality you're looking for. The aluminium bodies can be anodized, providing a protective layer and a wide range of color options for flashlight bodies. Anodizing enhances the corrosion resistance, hardness, and scratch resistance of the aluminum, while also allowing for a variety of attractive finishes.

The HAIII coating provides excellent corrosion resistance, protecting the underlying aluminum from exposure to moisture, humidity, and other corrosive elements. It helps maintain the appearance and functionality of the flashlight, even in harsh environments. The HK90 offers an impressive assortment of captivating colors: black, desert tan, silver.

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 HK90 features a smooth reflector (SMO). If long-range illumination and throw distance are the primary requirements, a flashlight with a smooth reflector may be more suitable.

The AR coating on the lens maximizes light transmission, making the flashlight more effective in darker environments. The HK90 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.


Flux18000 lm
Intensity750000 cd
Throw1732 m
CD/LM factor41.67

Flashlights with high lumen outputs are often larger and heavier due to the increased number of LEDs, advanced cooling mechanisms, and larger battery requirements. Consider the size and weight of the flashlight and whether it aligns with your intended use and portability needs. The HK90 is a 750000 cd flashlight. Flashlights with extremely high luminous intensity often require significant power and generate more heat due to the increased energy output.

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. Flashlights with a higher cd/lm ratio typically excel in long-range throw and focused beam applications, while flashlights with a lower cd/lm ratio may provide a wider and more evenly distributed beam for closer-range illumination or general-purpose use.


Mode memoryyes
Ramping modeyes

The HK90 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. Instead of having predefined brightness levels or fixed modes, the ramping mode lets you adjust the light intensity seamlessly within a specific range. The strobe function on the HK90 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 HK90 has an SOS signal mode. The SOS code consists of three short signals, followed by three long signals, and then three short signals again.

The power source of the HK90 flashlight is 3 x 21700 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.

USB rechargeable flashlights have become increasingly popular in recent years due to their convenience and sustainability. When the HK90 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 HK90 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 "7" in the IPx7 rating indicates that the HK90 flashlight, can withstand being submerged in water up to a certain depth for a limited time without being damaged. With an impressive impact resistance rating of 1 m, the HK90 flashlight is built to endure accidental drops or impacts, ensuring its resilience and dependable performance in demanding situations.


Package contents2 x spare o-rings
USB Type-C cable
gimbal screw

The lanyard of HK90 helps protect the flashlight from accidental damage by preventing it from falling or hitting the ground. When using spare O-rings, it's important to follow the manufacturer's instructions and guidelines for proper installation.

The performance of the Haikelite HK90 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.
