Olight M20SX Javelot is a nearly indestructible, rechargeable tactical flashlight loaded with critical tactical features.

The 20SX is the latest model and the maximum output has been upgraded to 820 lumens. The Javelot is a solid choice for law enforcement, hunting, search and rescue, and any other outdoor activities. It includes many tactical features including a weapon mount and remote pressure switch. The Olight M20SX  is a great flashlight in our Best Tactical Flashlight page.

The Olight brand is another leader in the flashlight industry and is known for their powerful lights and indestructible products. The brand started out in Europe and now targets military and law enforcement markets. The M-20SX Javelot is their newest model of the M-20X series and will not disappoint.

The M-20SX is nearly indestructible, made of Type III hard anodized aluminum which makes it extremely scratch resistant as well. It also has a crenelated stainless steel striking bezel for increased confidence and strength when you need to use it as a weapon. This light was created to withstand the most intense situations, and offers great durability for whatever type of situation you encounter, whether leisure or extreme. For added durability the flashlight is water-resistant. The light also includes thermal management technology to protect itself from possible damage due to overheating.


The LED is a super bright CREE XM-L bulb. At the highest setting, the output in this model has been increased to 820 lumens. The LED lamp is created using unique technology, allowing a light range of up to 370 meters. The customized CREE LED has a smooth reflector. This technology creates the tightly focused beam of light that has a throw of 370 meters.

This light is small for ease of carry, with dimensions of 5.6x1x1 inches. It only weighs 4.5 ounces. Although small, the aircraft grade durable aluminum body and crenelated stainless steel bezel can still pack quite a punch when needed. The M20SX Javelot runs on either 2- CR123A batteries or 1- 18650 battery. The light comes with integrated battery polarity protection which prevents the possibility of installing the batteries incorrectly.


The M-20SX has three light modes: high, medium, low, and strobe. The high mode has a max output of 820 lumens down to the low mode of only 25 lumens. This tactical flashlight includes some good special features. The M20-SX is a new generation of two-tail-switch tactical flashlight. The click tail switch allows for momentary activation along with being the on/off switch.

It also allows quick access simply to the brightest level when you need it most and the strobe mode when you find yourself in a dangerous or rescue situation. The side switch allows you to easily select the light mode you desire, and also includes a memory feature to remember the last light mode used. This light has a lot of available accessories depending on your needs, including a weapon mount, filter, and remote pressure switch. Included with the torch are a lanyard, battery magazine, 3 spare o-rings, and a silicon rubber boot.

What we like about it

We are always excited when we find a reliable tactical flashlight that can run in rechargeable 18650 batteries. This light really provides everything you need whether you are looking for an everyday carry torch, or for a light impossible intense and life threatening situations.

We like the ease of the momentary on switch along with the memory function. This light is extremely durable and has a crenelated stainless steel bezel that is not found in many of the other lights we reviewed. When checking out other reviews, here is what we found:

Many customers are drawn to this light because of the reliability or the brand Olight in making an indestructible product. One customer wrote- “Great improvements on an already amazing light. This thing throws! All of 350 yards out is lit up. The red filter works well with this light.” Another useful review stated- “This is my car light. It stays close at hand in case I ever need it, and I’ve used it a few times already. I love the fact that it can take either the standard CR123 batteries (that can be stored 10 years and still work) or with single 18650 batteries that recharge easily and hold a charge a LONG time.”

What we don’t like about it

One downside is that there is not an instant on for the strobe feature, so if you are in a panic you have to click through all the other modes to get to the strobe function which can be stressful in the heat of the moment.


When compared to the Ecogear TK120, this flashlight is expensive, but you truly are getting a reliable and a quality product for the price. If you can afford a high-end flashlight and want to have peace and mind when using your flashlight, then we would recommend this flashlight to you. It is very high quality and the abundance of tactical features allows it to be used in a variety of situations. You will never need another tactical flashlight after you have purchased this one.
