Klarus G35 - 2000 Lumens


Prepared to be blown away? One of the most impressive flashlights of 2017 is the Klarus G35. This flashlight is an illumination beast that delivers 2000 lumens of blinding power and can reach out as far as 1000 meters! This LED flashlight can shine over ⅔ of a mile and it fits comfortably in your hand! Thanks in part to the CREE XHP35 HI D4 LED and the incredibly deep reflector, the G35 will cut through the darkness like never before.

The G35 features dual independent switches - one tail switch and one side switch - allowing you to choose which switch you’d prefer for operation. It also has a lockout function so you don’t need to worry about the flashlight turning on in your bag. With the four brightness levels and two flashing modes, you can use this flashlight for a variety of situations. It features both a one touch-Turbo and a one-touch Low. When you’re using a really powerful light like the G35, you’ll really appreciate that one-touch Low so you won’t be blinding in close quarters. With its built-in memory mode the flashlight will remember the last brightness level you had it on.

The G35 runs on three 18650 batteries typically. However, in an emergency situation, it can run on a single 18650 battery or even two CR123 batteries. Just insert the battery or batteries into the red slot and you’ll have the flashlight working for you! When you first insert any batteries and turn the G35 onto Turbo the flashlight will detect if the batteries can support the flashlight’s full power and, if the batteries can’t, the Turbo mode will automatically decrease to ensure the batteries are used safely. With this protection you won’t need to worry about the batteries or flashlight being damaged. The G35 also features a battery power indicator that lets you know the current charge of the batteries.

Just like the other Klarus flashlights, you can expect the G35 to be ultra durable. It's constructed out of 6061-T6 aerospace aluminum alloy with a military spec HAIII anodized finish. It has a tempered glass lens with AR film plating for scratch resistant and to protect the LED. With ITS temperature control, you don't need to worry about the flashlight over heating. It controls and monitors the temperature ensuring the flashlight is safe, stable, and performing at its best. The G35 is impact resistant up to 1 meter and waterproof up to IPX8 standards. This LED flashlight will last you a long while. Batteries sold separately.

Klarus G35 - FlashlightZ Opinion

Author : David

It wasn't so long ago that the Klarus XT12GT was the latest model flashlight from Klarus. It's a very fun light. It made a big splash with its revamping of Klarus' magnetic charging system, removing the need for special magnetic cables and also the need for special bi-directional batteries. It's a pretty exciting step as far as Klarus' rechargeable items is concerned, but sunrise, sunset, there is now a new newest Klarus flashlight, which looks to be just as exciting.

It's called the Klarus G35. This is the latest light in Klarus' G series, which was previously capped at G30. What's happened with the G35 mostly is that there's been some really radical changes to the head. Where before the G30 was pretty much a solid tube, now you've got a light that's much more concerned with distance and beam throw than flood. The big headline here is that the G35 has a max beam distance of 1,000 meters. That is so many football fields that it doesn't even make sense to use that analogy because you lose the visceral sense of it. Partly how this is done is that the head is now much larger, much deeper and wider, so it's a much more dedicated design on the part of beam throw, and the light also has 2,000 lumens, which is comparable to that other great Klarus light with amazing power, the XT11GT.

The G35 is built with a slightly different purpose in mind. This is a light for outdoor, search and rescue. It needs to last for a while, so unlike the XT11GT, which runs on a single battery at the 18650 size, the G35 requires three. The reason for this is that it gives it a lot more runtime, so the G35 is a light, which at the lowest setting, can run for 210 consecutive hours. That's an overall time of eight days, eight days and change. This is a light that is not just built to be bright and to have a great beam throw, although it does have both of those attributes, but it's also a serious tool. If you're out not exactly near a 7/11, then this is something that you're supposed to be able to depend on, not just for dropping it, although we'll get to those sorts of attributes and talk about its general ruggedness and design, but it's meant to last you for a long time. Definitely its long runtime is a fantastic attribute.

If you don't have three 18650 batteries and you are in a pinch, Klarus has been so particular about making this the outdoor dependable light that they have made it so that it can work with just one. Just one 18650 lithium ion battery is enough to at least get it going in an emergency. That's enough to give you a little bit of light in low light conditions, use the SOS function.

Let's move onto the interface. The Klarus G35 has a dual switch system, one side switch and a primary switch on the tail. Unlike your regular tactical switch, this is a light which is designed to be used outdoors, search and rescue, overall less hostile environments. In terms of conflict resolution, this is more about, if anything, extreme survival situations. If you go to your primary switch, normally on a tactical light, that would you get you straight to the highest brightness, but the G35 is about preserving night vision and preserving battery power. What you've got there is you hit that button and the light instantly comes on at the lowest setting, 10 lumens. You still got some very good range for just being a 10 lumen output. It shows that the reflector has some excellent design. If you just need to read something or look at something right in front of you, going through your bag, definitely this easy access low light option is fantastic.

From there, you slide the brightness up until you're getting that full 2,000 lumens. Very handy. They probably could have stopped there, to be honest. For a light like this, that's sort of all you need. You still have access to strobe, which a pretty critical feature and something that Klarus has in just about every light that it comes out with. You got strobe and you got SOS, so those are very important.

They're all accessible, very intuitively, from the primary switch, but you've also got the side switch, and the side switch is in many ways the same way. It goes from low to bright. Strobe is a double tap and SOS is a double tap from strobe. In those respects, it works exactly the same way. What's nice, though, is that it does have a memory function, so if you don't want to be constantly only coming on in the low brightness setting, then what you can do is you can switch your side switch to whatever brightness setting it is you want and turn it off. Now you can access that brightness setting instantly the moment you turn the light on again. It's a very straightforward, very intuitive interface that has made the Klarus G35 the kind of survival and outdoor light that anyone really can operate very easily right off the bat.

Let's talk about just the body of the light for a second because it's actually a pretty nice design. It's got plenty of vents. 2,000 lumens is going to produce a lot of heat, but it's got a lot of venting, so it should keep cool. It's got some nice knurling on the body, so even if you're not wearing a glove, this is just a pleasant light to be holding in your hand. It just feels good. The buttons are very easily found. Even if you are wearing gloves or outside, you're doing some work or something, you should have no trouble locating the switches and accessing the light. Overall, just like the interface, very smart, very straightforward and sleek design on the body.

Another nice thing is that this carries over the Klarus XT11GT's ITS temperature control system. If you have it at the max brightness, for instance, for a long time and the light starts to get really hot, it will sense it and it will automatically dial back the brightness level to prevent damage and give the light a chance to cool. That's a pretty amazing feature for just a flashlight. That's something that can really save your butt if you're out far from somewhere, you're not thinking about your light. That's one less thing that you have to worry about in any situation. You don't have to be thinking about, "Am I overheating my light right now? Do I need to rein it in?", because your ITS can handle that for you.

Looking at the bottom of the light here, you got a little hole in it for a tactical ring or lanyard, making it a more transportable light. The tailcap is similar to the one used on the G30, not surprising since the body of the Klarus G35 is just about identical in how it looks. However, this tailcap looks like it's improved on some of the weaknesses of the G30's tailcap. Functionally, it seems to be the same, but if you look at it, you'll find something that just feels and sounds much sturdier than that tailcap. I think it's going to be an overall much, much more dependable light.

Some other smart features here. Going forward, the Klarus G35 is IPX8. That means it is not just weatherproof, but actually water tight in up to two meters of water. If you're standing in shallow water at the bank of a river or a lake and you drop this into the water, and after you've pulled it out of the mud and back out of the water, it will still work. Guaranteed. Klarus has a five years warranty on all of their products. If something like that occurs and, for whatever reason, it didn't keep working, Klarus would replace it, but checking out the light, we've never had any issues with its weatherproofing or waterproofing. It's just an incredibly tough, nice light. It's also impact resistant up to one meter.

When you're just carrying it around, it's got a nice lockout function, where both switches can be locked down to prevent any accidental activation during transport. You can just lock this light, really easy operation. You just hold both buttons for two seconds, and once it blinks at you, drop it in your bag and you know this super powerful light is going to stay dormant until you decide to use it. Then you take it back out, you tap either switch three times, and it's back to being a fully functional flashlight. That's a pretty critical feature to have in a flashlight this powerful, a 2,000 lumen flashlight. You don't want that to turn on and be rolling around in your bag, dispersing that kind of heat. To have the ability to lock both switches is part of what makes this a great light.

Just to summarize, what we've got here with this Klarus flashlight review is we've got a fantastic outdoor mini searchlight, incredible range at 1,000 meters, incredible brightness at 2,000 meters, but a smart, efficient interface that conserves battery power, yet gets you the brightness that you want as quickly as possible. It's tough. It's dependable. It's got a lot of subtle features, which make it easier to use and which make it a more dependable light. Didn't even get to things like the intelligent low check system, for which the light actually uses to check the batteries being used with it to make sure it's safe, or the indicator light, which gives you a rough idea of how much battery power you have left so you can plan out your flashlight usage. It's got just a lot of great smart features without being loaded down and being too complicated for anyone to just take out of a bag and use on a trip.

I do highly recommend. If you're going camping, if you're going on any kind of excursion where you need a bright, dependable, and intuitive flashlight, then I do recommend taking a hard look at the Klarus G35. I think that could be your light.
