Headlamps consist of a light source attached to a headband, allowing users to wear them hands-free.

Body

Weight	122 g
Length	124 mm
Head diameter	24.8 mm
Material	aluminium alloy with HAIII hard-anodized finish
Colors	black gun gray silver

This 122 g flashlight would be considered slightly heavier than average for a handheld flashlight, but it is still within a reasonable weight range. This weight range is often found in smaller and more compact flashlights designed for everyday use or portability. The length of the HL01 SST20 flashlight can affect its portability. A shorter flashlight is generally easier to carry in a pocket, bag, or pouch, making it more convenient for everyday use or when you're on the go.

Aluminium is a lightweight material, which is beneficial for HL01 SST20 flashlight. The HAIII coating can also enhance the visual appearance of the flashlight. It offers a uniform and attractive finish, often available in different colors, giving the flashlight a sleek and professional look. This flashlight offers a wide array of color options, allowing you to choose from a diverse range of hues to suit your personal style and preferences.

System

Emitter	Luminus SST20 LED
Color temperature	4000 K
Reflector	OP
Lens	AR coated glass
Switch	electronic front

The emitter of HL01 SST20 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 HL01 SST20 uses orange peel (OP) textured reflector. The orange peel (OP) reflector is a specific type of reflector commonly used in flashlights. It is named after its distinctive textured surface, which resembles the skin of an orange. The AR coating of the lens helps to mitigate these reflections by altering the refractive index of the lens surface. The HL01 SST20 utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.

Performance

Flux	1200 lm
Intensity	6900 cd
Throw	166 m
CD/LM factor	5.75
CRI	95

The 1200 lm output of HL01 SST20 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. With 6900 cd, the HL01 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. A flashlight with a higher CRI can provide better color accuracy when examining objects or distinguishing between different colors in low-light or nighttime situations. This can be beneficial in certain tasks or activities where color discrimination is important, such as identifying wires or reading color-coded information. With a CRI of 95, the HL01 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.

Software

Firmware	Anduril
Mode memory	yes
Ramping mode	yes
Strobe	yes
SOS/Beacon	yes

Anduril allows users to customize various parameters, such as mode spacing, mode order, and shortcuts, to tailor the flashlight's behavior to their specific needs and preferences. The HL01 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. The HL01 SST20 flashlight with ramping mode has a user interface that enables you to control the brightness level by pressing and holding a button.

The HL01 SST20 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.
