ThruNite TN12 Pro Rechargeable Flashlight, High 1900 Lumen LED Flashlight with Dual Switch, Long 415 Yards Throw, for Outdoor Rescue, Searching, Hiking and Emergency - Black Cool White

Five levels of brightness: 1. Firefly - long press side button then release. Bright enough during pitch darkness while camping. Will last for many days during survival mode if, God forbid, lost in the woods. Short click to turn off. 2. Low - quick click to turn on then release. Long press and hold while the light is on to cycle through the low, medium, and high setting. Release the button at desired setting at low brightness. Quick click to turn off. Quick click to turn on and it will automatically go to your last setting, which this time is low. Bright enough for everyday typical periodic usage and the battery will last for weeks. 3. Medium - follow the same steps to set as above #2. 4. High - same steps as #2. 5. Turbo - short click the tail button to turn on. Don't recommend leaving it on for more then a minute due to the high heat created from the concentrated light. If used at this setting for longer durations, it will automatically go to a lower brightness level. *(Repeated longer periods at the turbo mode will shorten the life of the flashlight due to repetitive high heat.) Lightly press the tail button without clicking to turn on but will turn off upon releasing the button. Suggestions: 1. attach the clip 90° to the side button where your fingers and thumb can touch the clip when holding the flashlight, while the button is pointed upwards for easy access for your thumb. So the next time you want to use the light, you will always know where the button is in relation to the clip if it's dark. 2. Place the flashlight in the holster with the side power button pointing towards the side of the holster to minimize accidental activation of the flashlight, such as when pressing against your body or external source. 3. Place a small round paper cutout between the battery and the contact if it will not be used for a long duration such as days or weeks. This will prevent drainage of power and possible leakage of fluid if stored for months. This flashlight is the smallest one that I own with the most illumination. Its ability to throw the beam at a distance is another feature not available in other flashlights. It provides the best of both worlds from the lowest practical light level, Firefly mode, to the brightest beam, Turbo mode, if distance illumination is necessary. It's an excellent flashlight for law enforcement, military (not during actual combat due to the lack of a red filter) or emergency personnel. As with anything, care should be observed if you desire long-term usage.

Replaced an earlier version of the same light. While as bright and long-lasting, the change in switch functions (turn on with what was the brightness switch or turn on brightest with end can), is a bit confusing, at least for someone used to prior configuration. Good value, small size very useful for every day carry.

My Mini-Maglite finally died after around 20 some years after dropping it. I decided on this torch after comparing dozens and watching YouTube reviews. Haven't needed to recharge it yet, as it came charged. Charging cable, lanyard, holster, clip and spare O-ring/Seals included. After reading the instructions and playing with it, (I have to read and play to retain info), it is very easy to operate. I found out that it is necessary to either single lock or double lock the torch. The side switch is a bit sensitive and can turn itself on accidently when putting in your pocket or holster. Brightness is really good. From the Firefly to Turbo mode. I was impressed with the amount of light from such a small torch. The price is good too. There are other torches with similar specs, but they are roughly twice the price and more. Good price, good product. Recommend this one.

The only thing I didn't like about this light was the different programing of the buttons compared to my other ThruNight lights. I still hit the wrong button sometimes. What Iike is: 1. lithium power lasts a long time, is rechargeable, and batteries don't corrode. 2 the firefly mode is a very dim light that doesn't blow your night vision. 3. The bright mode will light up a large area if you need it and it will momentarily blind someone if that is what you want to do. 4.The other modes fill in everything else. 5. With two switches you can access the mode you need without clicking through them all every time you use the light. This is really a great light if you value a quality flashlight. I travel with a power brick for the very occasional need to recharge, but I rarely do need it.

These used to be a great flashlight. Well made, provided a LOT of light or just a little with just a touch of the side button. I needed another one and when this arrived it was so hard to work single handedly I am sending it back. To adjust the light output you need to make sure it is unlocked, turn it on and then press and hold the side button so it may go through all of the light levels. Sorry, don't have time for that. I want to press the side button and each button press should change the light level; not waiting for the flashlight to do it for me. What happened to this flashlight? Who decided this was a good idea? Not for me. This is going back to Amazon and I'll order the Fenix version. Thrunite needs to abandon this "Upgrade." I won't be back to buy any more these.

The side button engages the flashlight. Great light I just would not recommend for pocket carry
