The cutting-edge Klarus ST15 is a compact tactical and powerful flashlight. Equipped with a CREE XP-L HI V3 LED and delivers a blinding maximum output of 1100 lumens with an impressive maximum beam distance of 305 meters. The ST15 features a tactical tail switch to turn ON and OFF the flashlight and a side switch to cycle through the brightness levels and access the strobe mode and SOS mode. This amazing tactical flashlight has four different brightness levels: Turbo - 1100 lumens, High - 400 lumens, Medium - 100 lumens, and Low - 10 lumens. It also features a flashing strobe mode for emergency non-lethal self-defense and an SOS mode to help draw attention in an emergency. With its built-in memory function, the ST15 will remember the last brightness level used.
For convenience, the ST15 has a battery capacity indicator so the user can plan the usage accordingly. It will glow green when it the battery is 70%-100% charged. It will glow orange when it is 30%-70% charged. It will glow red when the battery is under 30% and will flash red when the battery power drops under 10%. To prevent over-discharge, the flashlight will automatically reduce the output when the battery is almost drained. This way the flashlight can still be used in case of emergencies.
For safety, the ST15 has an integrated head and tube for proper heat distribution, has ITS temperature and output control, and has reverse polarity protection in case the batteries are loaded incorrectly. The ST15 is constructed from aircraft grade aluminum and has a dual spring system to absorb shock from the occasional drop. It is also waterproof up to IPX8 standards (submersible up to 2 meters).

Klarus ST15 - FlashlightZ Opinion
Author : Carolyn
We talk about tactical flashlights a lot, and we talk about everyday carry flashlights a lot, but today I want to look at the Klarus ST15, which I would consider an outdoor flashlight. This kind of flashlight is a little more broad than, say, a tactical flashlight or an everyday carry flashlight. It can be anything from the ST15, which it sort of looks like a tactical flashlight, or it can be the G20, which is quite a bit thicker, heavier, and has a floodier beam to it. I would say when looking for an outdoor flashlight, you probably want something that has several brightness levels that you can choose between, a strobe or an SOS mode just in case, and a flashlight that's compact, but still powerful. The ST15 is all of these things, and has more features that would make it an excellent outdoor flashlight.
So first let's talk about the lumens. The Klarus ST15 delivers 1,100 lumens at maximum power. This is an amazing amount of light. Today, we'll see a lot of flashlights that have 1,600, 1,500, or even 2,000 lumens of power, and these are amazing flashlights, and it's amazingly powerful, but you don't always need 2,000 lumens. 1,100 lumens is a great amount of power, especially in an outdoor flashlight. So you have the tactical tail switch that you can use to turn the ST15 on and off, and the side switch that allows you to cycle through all the different brightness levels and the different modes.
The ST15 has four different brightness levels. You've got turbo, high, medium, and low. They range from 10 lumens being the lowest, to 1,100 lumens, which would be turbo. So it's excellent to have different brightness levels. You're not always going to use that turbo level. With the low level and the medium level, you might find yourself using that a little bit more often because at night, say if you're camping, if you're out in a tent, it's a lot easier to use that low mode whenever you're reading a book at night, or maybe you're looking in your bag for something. You don't really need 1,100 lumens to be looking in your bag. That's a little too bright. It might even blind you a little bit.
The ST15 also has flashing modes, a strobe mode and an SOS mode. I had to watch a Klarus flashlight review of the ST15 to remember exactly how you access the modes. For the strobe mode, all you have to do is double click the side switch, and then another double click will get you into the SOS mode. The reason the Klarus ST15 is not considered a tactical flashlight is mainly because it does not have immediate access to that strobe mode. Double clicking is a little too, I guess, tedious to be considered an immediate strobe, however, outdoors, it still makes an excellent flashlight, and that strobe mode can definitely come in handy, not to mention that a lot of outdoor enthusiasts actually prefer the SOS mode to the strobe mode, as the SOS mode helps to attract attention when necessary.
I believe an important feature to have in an outdoor flashlight is a built-in memory function mode. The ST15 does have this mode, and it allows you to turn off the flashlight, say, in the low mode, and the Klarus ST15 will remember that you had it in the low mode, so when you turn it back on, it'll be in that mode. When you're out at night, and say you don't want a lot of attention drawn to you, that mode, that built-in memory mode is going to be an excellent thing, an excellent feature for you to have.
The Klarus ST15 runs on a single 18650 lithium ion battery, or you can equip it with two CR123 lithium batteries. On the side switch, you will see a little LED battery capacity indicator so that you can plan your usage. This is an amazing feature to have in an outdoor flashlight, especially when you need to worry about conserving the battery. When that little LED glows green, it means the battery is at 70% to 100% charged. When it glows orange, it is at 30% to 70% charged. When it glows red, it means it's under 30%, and when it flashes red, that means that the power has dropped under 10%, so it might be time to change the batteries or take the batteries out and charge the batteries, whatever it is you need to do.
When the batter is almost drained in the ST15, the flashlight will automatically reduce the output, thus preventing over-discharge. This is crucial for outdoor flashlights. This allows the ST15 to still be used in case of emergencies. Of course, with any Klarus flashlight, you can expect high quality, and the ST15 is no different. It has an integrated head and tube that properly distributes the heat, so you wouldn't have to worry too much about the temperature of the flashlight. It also does have ITS temperature and output control, which I talked about a little bit before.
It also has reverse polarity protection, which means that you don't have to worry about damaging the flashlight or damaging the batteries if you load the batteries in incorrectly. This is actually pretty common, especially if you're loading the batteries at night, or if maybe you are loading them in a hurry. It can be pretty common to load the battery incorrectly, and if this is the case, the flashlight simply will not turn on, but no damage will be done to either the flashlight or the battery.
It is constructed from the aircraft-grade aluminum, making the Klarus ST15 an incredibly durable and sturdy flashlight. This is what you need in a flashlight to go outdoors, whether you are hunting, camping, fishing, hiking, whatever it is, you want something that's durable and that'll work perfectly with any drops or bang-ups that might happen. Thanks to that dual spring system that is so common in Klarus flashlights, it can absorb the shock from an occasional drop. You will also notice that the battery will not be moving around quite a bit. If you shake the flashlight, the batter won't move. That is, in part, thanks to that dual spring system that's in place.
The Klarus ST15 is also waterproof up to IPX8 standards, which means you can drop it in two meters of water, and leave it there for 30 minutes, and this flashlight will still work perfectly fine. All flashlights, or more likely, all outdoor enthusiasts, have had that happen where they've been outside, and it suddenly just starts raining or down-pouring. You don't want to have to worry about covering up a flashlight, or just having to not use it at all because of damage from the water. I think in the rain is probably when you need light the most, especially if it is storming at night. The ST15 has got your back for this. You can take it out into a heavy rainstorm and know that it will work perfectly. You don't have to worry about drying it off too much. You don't have to worry about trying to shield it from the water. This flashlight is there for you, and it will definitely deliver.
The ST15 comes with many accessories, as to be expected from most Klarus flashlights. The ST15 comes with the Klarus 18650 2600 mAh battery. It comes with a holster, a lanyard, a pocket clip that you can remove, and a sparrow ring in case yours may break. So you've got the holster, allowing you to carry this flashlight quite easily. You have the pocket clip that allows you to clip it to your pocket, your shirt. I've seen people clip it onto their hat. I guess you can just clip it wherever you can think to clip it, and of course, that lanyard is also an excellent tool that you can use to carry your flashlight around. So you have different options to carry this flashlight however you feel comfortable.
I watched GearNuts's Klarus flashlight review over the ST15, and he pointed a feature out that I would like to talk about now. When looking at the tail cap of the ST15, you'll notice there's a stainless steel ring, and you can rotate it around. This is the lanyard ring. So whenever you put the lanyard on the flashlight, you're holding the flashlight, if you rotate it in your hands, the lanyard will not get tangled because of that rotating, silver lanyard ring. It will not get tangled. It'll just move along with you. That is an awesome feature and one that I can't believe I had to watch a review to realize. Having a side switch can be a negative aspect when it comes to lanyards because you're searching for that switch, you're rotating the flashlight in your hands, the lanyard can get tangled or just twisted, and it's not really comfortable, you have to sort it out, so that silver ring is an excellent addition, so kudos to Klarus for that.
All in all, if I were to pick a Klarus flashlight that I would take with me on an outdoor venture, it would absolutely be the Klarus ST15 almost every time. This flashlight has everything you would want in an outdoor flashlight.
