Thrunite Scorpion V2 LED tactical flashlight, 750 lumens, uses 2 x CR123A or 1 x 18650 batteries

ThruNite Scorpion V2 LED Flashlight

The ThruNite Scorpion offers lots of throw with an easy to use, well-designed interface great for tactical and law enforcement applications. The new version (V2) raises the bar, pushing the output to 750 lumens out the front!

Its one-inch body can be easily adapted for weapon mounting and it has a range if over 200 meters (about 650 feet). The scorpion uses the newest, top of the line Cree XM-L LED with a smooth reflector. It has 5 modes of output (Lock Out, Firefly Mode, Infinite Brightness from 8-89%, Momentary On, and Momentary Strobe), which can be easily accessed by rotating the ring on the tailcap. All stages are completely silent, ideal for tactical situations. It also has a removable grip ring, clip, and stainless steel crenelated bezel, which can be used in a variety of applications.

Modes and Operation:

The Scorpion features a unique five stage UI with a twist ring on the tail cap. The ring rotates from left to right for the following modes: Lock out, Infinite Brightness, Firefly, Momentary Strobe, and Momentary On.

• Lock Out: Prevents accidental activation of the light. This is important when storing or transporting the light, or in situations where accidental activation of a light can be dangerous. To select this mode, turn the light on in Infinite mode (which is the first mode when the tailcap mode selector is twisted all the way to the left). With the button fully depressed (now turning the light off), rotate the ring counter-clockwise while slowly releasing the button to lock out the tailcap. It's like driving a clutch, it takes a few tries but when you get the hang of it you're golden.
• Infinite brightness mode: Customize the brightness you want. Press the click and hold, the light will start to ramp in brightness, choose the brightness you want (8% through 89%) and then release, the light will memorize the setting. It will retain this setting for future use on this mode.
• Firefly mode: This mode was specifically designed with the tactical user in mind. It has a very low 0.2 lumen which is perfect for stealth navigation and for map reading without excessive glare to the user.
• Momentary Strobe: This is for tactical applications as well. Press and hold for on, release for off.
• Momentary Function: This is for tactical application where you need short bursts of light. Just hold down the switch for on, release it for off. This mode will always give the max output.

Improvements for the V2 Version:

• Momentary On and Momentary Strobe now get a kit for brightness. The maximum current driven with 2 x CR123A batteries is 3A. This makes the out-the-front output 750 lumens for 1 minute. The circuit will automatically lower the output to 89% brightness (driven around 2.5A) to keep from damaging the batteries from the high discharge rate. When using a Li-Ion 18650 battery, output will be 660 lumens OTF. This maximizes the output when you need it most for quick spurts in tactical situations.
• Different User Interface: By request from the military and tactical users of the original Scorpion, the sequence of the user interface has been changed. The new sequence of modes is: Lock Out, Infinite Brightness, Firefly, Momentary Strobe, and Momentary On.
• The linear brightness ramping has been replaced by logarithmic ramping. This make the ramping look virtually smooth and comfortable to the eye and much easier to set. The ramping time is also shorter, making it more convenient to find the perfect brightness. A reverse ramping function has also been added. If you miss the brightness level you want while going up, just switch it on a again and it will come back down. Now you don't have to wait for an entire cycle. The infinite brightness varies from 8%-89% (150mA-2.5A), which gives a full range to choose from to find the perfect amount of light for any situation.
• The current regulation has been changed from PWM (Pulse-Width-Modulation) to Current Control. Though PWM works well, on low modes the flicker can be noticeable. Some people are more sensitive to the flicker of Pulse Width Modulation. With current control, the output is smooth and constant even on the lowest levels.
