I have several outdoor tool lights, and this is my favorite out of all of them. It's brightness, size, weight, look, features, and functionality win the race in all categories. I Dig It 👍

I absolutely love this Klarus tactical light. The mounting system is one that I have never seen but it's great! It attaches and detaches from the pressure switch in an instant and it is rechargeable via a USB cable. This is my new favorite tactical light. I highly, highly recommend it!

If you’re looking for one of the best tactical weapon lights for under $130 USD, the Klarus GL4 has got to be on your list of consideration. This is a very well made, super bright, darkness slayer, that will guide you to your target during the night like its daytime.

What I like:
I. This light is extremely bright for its size or any size for that matter. It comes with a 5000mAh rechargeable lithium battery, aluminum construction, tactical features, great size that fits in my hand so nicely, remote mounted buttons, and rail mounting tactical clip.

II. This really is a top of the line flashlight, the build quality, materials used, features and functionality are all 5 star and I can’t imagine anyone saying otherwise.

Overall, this is a really well built flashlight that definitely deserves your consideration. It’s extremely bright, comes with a huge rechargeable lithium battery, and is constructed super solid. If you’re ok with the price, they decide to lower it, or you can catch it on sale, this would be a fantastic light worth owning that will give you years of very happy, dependable great service as your go-to gun light.

I am impressed with this weaponlight as it appears nearly as good as my higher end versions that cost several times as much.

I mounted this on the Pic rail of my rifle, and it has been very secure with easy access. For simplicity, I will list the pros and cons below:

- Compact at 5.5 inches long with a 1-1/8-inch diameter across the crenulated bezel.

- Weighs only 7.9 ounces with the Picatinny Mount and the battery installed.

- Is very bright with a decent spread and focused center beam.

- Easy to use tactile push buttons on the pressure pad which comes with a removeable Pic mount.

- The Tail Cap is relatively straightforward to use but has more than one button. The main push-button is the on/off switch. The three-dot angled button on the edge of the cap is the button that functions for changing the illumination settings (I would have preferred just to be able to cycle through the settings with the main button).

- I’m glad it has a strobe setting, as it is useful for disorienting an attacker.

- Uses a removeable rechargeable 5000mAh Li-Ion battery and can be charged within the light via a USB-C cable. There is an illuminated charging light: Red it’s charging, green indicates charging is complete.

- Uses the more durable and easier to use USB-C charging connection.

- Waterproof IPX8 rating and shock resistant. Seems to hold-up to recoil just fine.

- Will stay illuminated for up to approximately 4-hours on Turbo, 7-hours on high, 13.5-hours on medium, and 375-hours on low.

- Has a battery status indicator light that illuminates 5-seconds after the light is turned on: Less than 30% battery remaining and it’s red, 30% to 70% and its orange, over 70% power remaining and it’s green.

it is a decent weaponlight that isn’t too large or cumbersome and which will apparently hold-up to abuse.

I'm surprised I haven't burned a hole through my wall with this yet. I have zero complaints about brightness. It's like the light of god shining down from on high, BUT...It gets hot, very hot. In short bursts like you'd be likely to use this in I think it's good to go.
