The SD90 flashlight enhance personal safety and security. It allows you to illuminate dark areas, identify potential hazards, or deter threats by shining light on them.
|Body diameter||52 mm|
|Head diameter||90 mm|
|Material||aluminium alloy with HAIII hard-anodized finish|
This 859 g flashlight is quite heavy for a handheld flashlight. The increased weight can provide advantages such as longer runtime, enhanced durability, and the ability to project a brighter and farther-reaching beam. The ideal length of a flashlight depends on personal preference, intended use, and the specific features and functionality you're looking for. The aluminium body of SD90 has excellent thermal conductivity, meaning it can effectively dissipate heat generated by the flashlight's components, such as the LED or battery.
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 SD90 flashlight is offered in a stylish black color.
|Emitter||Luminus SBT90.2 LED|
|Color temperature||5700 K|
|Lens||toughtened AR coated glass|
The emitter of SD90 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 SD90 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 SD90 flashlight. The SD90 utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.
With 7500 lm, the SD90 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. 730000 cd represents an extraordinarily high level of brightness. 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 SD90 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 SD90 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.
|Battery||4 x 18650 Li-Ion batteries|
|Charger port||USB Type-C|
|Impact resistance||1 m|
The Lumintop SD90 flashlight is powered by 4 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 "6" in the IP68 rating represents the level of protection against solid objects, specifically dust and foreign particles. It indicates that the SD90 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.
With an impressive impact resistance rating of 1 m, the SD90 flashlight is built to endure accidental drops or impacts, ensuring its resilience and dependable performance in demanding situations. The SD90 flashlight can be used as a powerbank to recharge a device, such as a mobile phone.
|Package contents||2 x spare o-rings|
USB Type-C cable
The lanyard of SD90 helps protect the flashlight from accidental damage by preventing it from falling or hitting the ground. 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 Lumintop SD90 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.
