The body and materials:

The SRT7i has been designed as an evolution of the successful previous model, the SRT7GT, and features several significant improvements. One of the most distinctive features of this flashlight is the fourth generation of the Smart Selector Ring (SSR), a rotating ring located on the back of the flashlight that allows intuitive control of brightness modes and special functions. This innovative design allows you to adjust the brightness with a simple twist, making one-handed use of the flashlight extremely comfortable and convenient. Additionally, the SRT7i features two dual-stage buttons located at the rear, offering even more precise and personalized control of settings.

The Nitecore SRT7i uses a powerful Luminus SFT-70 LED, capable of producing a maximum output of 3000 lumens and reaching a lighting distance of over 580 meters. This means that the flashlight offers a significant light output, allowing you to illuminate large areas and tackle situations where visibility is essential. Furthermore, thanks to the advanced optical system and the crystal coating with Precision Digital Optics (PDOT) technology, the light beam is uniform and well focused, ensuring clear and detailed vision even at considerable distances.

The SRT7i is powered by a 5000 mAh "i" series lithium battery in 21700 format, included in the package, which guarantees a maximum autonomy of 800 hours. This battery is rechargeable via the flashlight's built-in USB-C port, allowing for convenient and fast recharging. In addition, the SRT7i is also compatible with two CR123A batteries using an adapter (not included in the package), offering greater flexibility in power supply. The flashlight is equipped with an intelligent charging circuit for the lithium-ion batteries, which protects against overcharging and over-discharging, ensuring a longer battery life over time.

From a construction point of view, the Nitecore SRT7i has a solid body made of aeronautical aluminum alloy with an HA III military grade anodized finish, which gives it resistance to wear and corrosion. The flashlight is designed to be shock and weather resistant, with a shock resistance of up to 2 meters and an IP68 rating, making it waterproof to a depth of 2 metres. These features make it suitable for use in extreme conditions and harsh environments, such as during search and rescue operations or tactical missions.

The Nitecore SRT7i offers a wide range of features and lighting modes. In addition to stepless brightness adjustment from 0.1 lumens to 3000 lumens, the flashlight features special modes such as TAC mode (tactical mode) for quick access to low and high power settings, and lockout mode to prevent accidental activation. In addition, thanks to the STROBE READY™ technology, you can quickly access the strobe mode for self-defense or emergency signaling purposes.

The Nitecore SRT7i is also compatible with a series of optional tactical accessories, such as the tail cap with TSL10i signaling LED and the RSW2i remote control, which further expand the functionality of the torch. This versatility makes it an ideal choice for law enforcement, assault operations, self-defense, research, and high-risk patrols.

The beam and the tint:

The Nitecore SRT7i offers a powerful and versatile beam that meets a wide range of lighting needs. The flashlight projector features a SMO (smooth) reflector that focuses light into a central point with a wide surrounding illumination beam. The light beam has a pleasant and well-balanced tint. When illuminating a wall or surrounding area, a bright white spot is seen in the center of the beam, surrounded by a slightly more yellow corona. This combination delivers even, balanced illumination, which is great for a clear, detailed view of your surroundings. The flashlight allows stepless brightness adjustment from 0.1 lumen in Ultralow mode to 3000 lumen in Turbo mode. This means that you can easily adjust the light intensity to your specific needs in any situation. The stepless dimming also allows for a smooth transition between different brightness levels, avoiding sudden changes that could disturb your vision or your surroundings. The Nitecore SRT7i offers an excellent performance in terms of illumination distance. The torch has a maximum peak beam intensity of 87,500 candelas and can cover a maximum distance of 580 meters. This makes it suitable for use in outdoor environments, in research situations or during security tasks and tactical applications. In summary, the light beam of the Nitecore SRT7i offers a combination of power, versatility and quality of light. Thanks to the stepless brightness adjustment and its ability to cover a large distance, this flashlight is able to adapt to different lighting needs and offer a clear and detailed view of the surroundings.
