Nitecore FLASHLIGHT SRT SERIES/3000 LUMENS SRT7I NITECORE

The Nitecore SRT7i is a high-performance tactical flashlight designed for professional use in law enforcement, military, search and rescue, and outdoor applications. Its standout feature is the 4th generation Smart Selector Ring (SSR), which provides intuitive and seamless control over its various modes and brightness levels.

Here's a detailed description:

Key Features:

• Superior Performance:

  • Max Output: Up to 3,000 lumens, providing intense illumination.

  • Max Beam Distance: Reaches up to 580 meters (approx. 634 yards), making it excellent for long-range searching and targeting.

  • Max Beam Intensity: 87,500 candela.

• Smart Selector Ring (SSR) & Dual Tail Switches:

  • Stepless Brightness Adjustment: The SSR, located on the tailcap, allows for precise, stepless adjustment of brightness from 0.1 lumens (Ultralow) up to 3,000 lumens (Turbo). This provides unparalleled flexibility to adapt to any lighting need.

  • Tactical Modes: The ring also allows quick selection of specific modes, including:

    • TAC Mode: Designed for tactical situations, offering instant momentary access to Turbo or Low output via the tail switches.

    • Strobe Mode: Instant access to a disorienting 3,000-lumen strobe with a randomly changing frequency for self-defense or signaling.

    • Lockout Mode: Prevents accidental activation during transport or storage.

  • Dual Tail Switches: Complementing the SSR are two tail cap buttons: a main power button (round) and a larger mode button (paddle-shaped). These enable intuitive one-handed operation for momentary or constant illumination and quick mode changes.

• Durable and Robust Construction:

  • Aero-Grade Aluminum Alloy: Constructed from a high-strength aluminum alloy.

  • HA III Military Grade Hard-Anodized Finish: Provides excellent resistance to wear and corrosion.

  • Crenelated Strike Bezel: Features strengthened tips with hard silicon nitride ceramics, making it an effective tool for glass breaking in emergency situations.

  • IP68 Rating: Waterproof and submersible up to 2 meters.

  • Impact Resistance: Withstands impacts from up to 2 meters.

  • Optical Lenses: Double-sided anti-scratch coating for enhanced durability and light transmission.

  • Advanced Temperature Regulation (ATR): Regulates the output of the flashlight based on working conditions and ambient environment to prevent overheating and maintain optimal performance.

• Power and Charging:

  • Proprietary 21700i Battery: Powered by a high-capacity 5,000mAh Nitecore NL2150HPi 21700i Li-ion battery. This "i Series" battery has positive and negative polarity on both ends for highly efficient output. It is only compatible with Nitecore 21700i Series batteries with over 15A output, or 2x CR123/RCR123 batteries (using a CR123A carrier, but these cannot be recharged inside the torch). It is not compatible with conventional 21700/18650 batteries.

  • USB-C Rechargeable: Features a built-in USB-C charging port for convenient and fast recharging. A full charge for the 5000mAh 21700i battery takes approximately 2 hours 30 minutes with QC charging.

  • Battery Level Indicator: A blue LED indicator displays the remaining battery power.

• Design and Usability:

  • Compact Size: Length of 163mm (6.42 inches) and head diameter of 40mm (1.57 inches).

  • Weight: 175g (6.17 oz) excluding battery.

  • U-shaped Tail Cap: Designed to prevent accidental activation and allows for tail standing.

  • Accessories: Comes with a holster, clip, lanyard, spare O-ring, and USB-C charging cable.

Output and Runtime (approximate, using NL2150HPi 5,000mAh battery):

• Turbo: 3,000 lumens; Runtime: 3 hours 15 minutes (this is the total runtime including regulated output, as ATR may reduce output to manage heat).

• Low: 100 lumens; Beam Distance: 110m.

• Ultralow: 0.1 lumens; Runtime: 800 hours; Beam Distance: 5m.

• Strobe: 3,000 lumens.

The Nitecore SRT7i is a highly advanced and robust tactical flashlight, prized for its versatile control, powerful output, long throw, and durable construction, making it suitable for demanding professional and outdoor environments
