Luminus has established a positive reputation as a reliable LED manufacturer. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. 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 electronic switches may have a higher likelihood of standby drain compared to mechanical switches.

Flashlights with high lumen outputs are often larger and heavier due to the increased number of LEDs, advanced cooling mechanisms, and larger battery requirements. 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. Candela per lumen (cd/lm) is a measure of a flashlight's beam intensity relative to its total luminous flux or output.


Mode memoryyes
Ramping modeyes

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 is designed to create a disorienting or attention-grabbing effect. 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. The battery indicator 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.

The Low Voltage Protection helps to preserve the battery's capacity and prevent it from reaching a critically low voltage level. The thermal protection 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 flashlight, can withstand being submerged in water up to a certain depth for a limited time without being damaged. The HK90 flashlight proudly boasts an exceptional impact resistance rating of 1 m.


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.
