It’s very bright and easy to setup.

Wow, this is the BRIGHTEST light I've ever owned. We'll worth it, fits nice on my rifle. It lights up the whole woods at night, with nothing to hide.

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.
