This flashlight is incredibly bright and simple to use, which is perfect for someone like me. I use it mainly for walking the dog in the evenings, and it lights up the path so well that I feel much safer. I love the adjustable focus—it’s handy to switch between a wide beam for general visibility and a focused beam for spotting further ahead. It’s sturdy, and the waterproof design means I don’t have to worry if it starts raining.

I bought this to replace my old flashlight which just stopped working. I read plenty of reviews and it appeared to be worth the extra money. Well you're no kidding. It is way brighter and happily shines well down to the end of an acre field or further. Great for finding the dog at night!! Even the least bright powered light is more than adequate for walking around in the dark. I have to say I'm really impressed.

Nice evenly lit moonbeam great for taking inspection photos. The zoom works well when needed. The flashlight always turns on in the high mode- it does not remember the last setting and I would prefer that it turn on in the low mode.

I have a soft spot for flashlights these days and I was happy to take the opportunity to try out this klarus EP12 flashlight.

You definitely get what was promised in the product description, a very bright, (more or less) robust zoomable LED flashlight with an in-house 4000 mAH 21700 battery.

The light image is largely OK, I think it's positive that in zoom mode the otherwise so often seen square illuminated area is simply not there and here too a nice, pointed round area can be seen, which many do less well. The emitted circle is quite homogeneous overall and really nice without zoom.

Another positive thing to mention about the zoom is that it is adjusted by turning the lamp head and therefore does not adjust accidentally.

I am quite sure that the brightness of this klarus EP12 reaches the advertised 2000 lumens, because other 2000s of mine are at a similar level, although for example It is definitely praiseworthy that the product description does not, as is often the case, give any utopian fantasy values.
It should also be mentioned here that in my opinion 500 lumens is usually more than sufficient for "normal" use and you will probably rarely use this klarus EP12 at the brightest level.
Although not really premium, the klarus EP12 is rather high quality and without any notable weaknesses it is still well made.
The operating concept of the lamp is really simple and above all good. Switch on at the highest brightness level, then each subsequent click is one level darker, you can get to the SOS by pressing and holding. The lamp can be switched off with a simple click after it has been lit for a few seconds, which is what I would like for some other people too. If I could wish for something else, however, it would be that the lamp would remember the last brightness level.

After removing the transport lock in the battery compartment, you can start using it.
Briefly press the power button and the flashlight lights up, the button lights up green, if you briefly press the button again, the light goes off again - it's that simple, I'm impressed - yes, seriously.
(With the last flashlight I tested, despite the instruction manual, it took me half a day to figure out how to deactivate the night light...)
Anyway, this flashlight only has 2 other functions besides the on and off function: If you press the button again within 3 seconds of switching it on, the brightness is reduced. And if you press the button for 2 seconds, it flashes "SOS". But if you briefly press the button again, this nonsense is completely deactivated again.
The lamp is made of metal and very robust. It is larger than I would have expected from the product photos.
The light is really extremely bright. The large beam of light even illuminates the living room during the day.
It is more than sufficient if you dim the lamp by one level.
At maximum brightness, the lamp becomes lukewarm after a short time.
The size of the light cone can be changed by turning the cap.
The lamp is charged using the USB cable provided. The large battery is replaceable.
