The HK04 SST40 flashlight offers precise and focused illumination. Unlike ambient or overhead lighting sources, flashlights allow you to direct the light exactly where you need it.

Body

Weight370 g
Length140 mm
Body diameter46 mm
Head diameter56 mm
Materialaluminium alloy with HAIII hard-anodized finish
Colorsblack
brown

This 370 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 affect how it feels in your hand and how you can grip and maneuver it. A longer flashlight may provide a more substantial grip, making it easier to hold and control, especially if you have larger hands.

The aluminium body of HK04 SST40 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 HK04 SST40 flashlight is available in assorted colors: black, brown.

System

Emitter4 x Luminus SST40 LEDs
Color temperature5000 K, 6500 K
ReflectorSMO
Lenstoughtened AR coated glass
Switchelectronic side

The emitter of HK04 SST40 manufactured by Luminus, a US-based LED manufacturer. Luminus is recognized as a reputable LED manufacturer in the lighting industry. They are known for producing high-quality LEDs with excellent performance and reliability. Color temperature is a characteristic of light. It is measured in units called Kelvin (K) and is used to quantify the color appearance of light sources, particularly white light.

The HK04 SST40 has a smooth reflector. The properly focused smooth reflector gives you a more cohesive hotspot and therefore throws better. 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 HK04 SST40 flashlight. The HK04 SST40 utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.

Performance

Flux9000 lm
Intensity180625 cd
Throw850 m
CD/LM factor20.07

With 9000 lm, the HK04 SST40 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. 180625 cd represents an extremely high level of brightness for a flashlight. 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.

The Anduril firmware is an open-source firmware developed for flashlights. It is designed to provide advanced control and customization options, offering a high degree of flexibility and functionality. The HK04 SST40 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 advantage of the ramping mode is that it offers precise control over the amount of light emitted by the flashlight.

The HK04 SST40 is tactical strobe ready. The strobe light is disorienting to the person it is aimed at which makes it difficult for them to concentrate. It has the SOS beacon function for an emergency situation. The SOS flashes Morse code so you can signal for help when needed. The SOS signal is recognized as an international distress call and is used to indicate an urgent need for assistance.

The Haikelite HK04 SST40 flashlight is powered by 3 x 18650 Li-Ion batteries. The battery indicator lets you know when the battery is low, charging, or fully charged. The USB charger port on a flashlight can be particularly useful in emergency situations where access to power outlets may be limited. This flashlight has a built-in low voltage protection (LVP) to prevent damage to the cell from over-discharge, so protected cells are not necessary.

The built-in thermal control automatically adjusts brightness output to prevent overheating. The "7" in the IPx7 rating indicates that the HK04 SST40 flashlight, can withstand being submerged in water up to a certain depth for a limited time without being damaged.

Accessories

Package contents2 x spare o-rings
USB Type-C cable
lanyard

By securing the flashlight with a lanyard, you can free up your hands for other tasks while keeping the flashlight within reach. 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 Haikelite HK04 SST40 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.
