Olight S2R Baton II Review

Olight S2R Baton II

A good, nay, a great flashlight is one of the primary tools you need to have in a survival kit. You need to be able to see in the dark, especially after an event like a hurricane or wildfire shuts the power grid down.

But why do you need a great flashlight and not just one you can grab off the shelf for $5? It's simple: performance and reliability.

You have to have something that will work when you need it, that can take a beating and still perform, and that gives you what you need - the ability to see in the dark.

You don't want to just see in the dark, you want to be able to really be able to see and assess your surroundings. You'll need a truly powerful light to do that.

With all that said, allow us to introduce you to the Olight S2R Baton II. It's a fantastic piece of gear that does everything you need it to, and more.

The Best LED Flashlight

The Olight SR2 is one of the best LED flashlights in the market. It has everything you could want:

  • Super bright light with 6 different output levels
  • Huge 18650 battery which runs nearly forever
  • IPX8 waterproof
  • Small enough to carry everyday in a pocket
  • Built-in magnet for hands-free use
  • Power indicator light

Let's look at each of these features further and dive into the numbers for those who like numbers (like me.)

Light Output Characteristics

The SR2 Baton II puts out 1,150 max lumens and 4,600 candela.

Lumens refers to the total amount of light emitted by a lighting device (in this case an LED torch light). The higher the lumens value, the greater is the area lighted up by it.

Candela refers to the amount of light emitted by a light in a particular direction.

When buying an LED torch light, you aren't really concerned about its lumens value because you will only use this device to illuminate a very small area, and that's candela.

The Olight SR2 Baton II uses a TIR lens to produce a balanced beam, which gives you good visibility characteristics across the entire beam.

In other words, no glaring bright spot surrounded by washed out light, just a nice even illumination up to 135 meters (440 feet) away.

There are three standard light, turbo, moonlight, and strobe modes. 5 in all.

Battery & Longevity

The Baton has my favorite battery in it, the 18650 powerhouse. If you aren't familiar with them you should be. They are rechargeable and have huge capacities, and if I'm not mistaken is what Tesla uses in their vehicles battery arrays.

The version Olight uses a custom button-top 3,200mAh (milliamp hours) 18650 battery which is included with the light.

  • LEVEL 1: 1150 lumens - Run-time (2 minutes) then drops to 400 lumens (230 minutes) 
  • LEVEL 2: 400 lumens - Run-time 4 hours 
  • LEVEL 3: 120 lumens - Run-time 14 hours 
  • LEVEL 4: 15 lumens - Run-time 100 hours 
  • LEVEL 5: 0.5 Lumens - Run-time 60 days

The S2R Baton II has a tri-color battery indicator located on the side switch so you always know when you need to charge it up.

One of the coolest features of the Olight products is the magnetic charging cable. It's always surprised me that more companies don't use something like this.

Yes, it is a proprietary cable, but the battery can be taken out of the flashlight and charged externally if need be if you have the right kind of charger.


On the other end is a USB connector, so you can easily charge the Baton II off of a portable USB battery bank or solar panel.

One added benefit of a magnetic charging system: now there is a powerful magnet under the light. Use it to attach the torch easily to any metal surface, like a car hood etc.

Upgrade: get an 18650 battery with a built-in micro-USB charging port - so you now have a 3rd way to charge the battery up should you lose the cable or not have an external charger large enough.

Form & Function

The Olight SR2 Baton II is small, compact and light-weight. It's easy to slip into a pocket without being overtly bulky or getting in the way.

  • Weight (g / oz) 98.5 / 3.47
  • Length (mm / in) 100 / 3.94
  • Head Diameter (mm / in) 23 / 0.91
  • Body Diameter (mm / in) 23 / 0.91

It fits in the hand nicely, and has a good textured grip which would assist with holding in wet weather. It feels solid in the hand, well crafted and finished.

There are two dual-direction pocket clips included, one blue, one black. They can be removed and changed easily.

The IPX8 rating means it will work underwater (at 1 meter) continuously, so no worries about it functioning during a rainstorm.

It is also drop test rated at 1.5 meters. It's a sturdy little torch and unless you drop it off the roof of a building I think it would be difficult to break.


  • Small everyday carry size
  • High output and battery life
  • Durability and waterproofing
  • Ergonomics


  • Proprietary charging cable
  • Unique battery (for some)


This is the perfect small flashlight for everyday carry or backup emergency use. Durable, long-lasting and compact enough to carry anywhere.

We recommend these and think you'll agree.
