Review: Olight S1R Turbo ultraportable 900 lumen flashlight

The Olight S1R Turbo S is a flashlight. What can one write about a flashlight? Turn on. Shine out far and wide. Turn off. Repeat. I thought that way too.

Olight is one of those brands that makes flashlights that have well thought extra features that just make them ideal and convenient to use. Most notably the magnet on the back and the “no-disassembly-required” charging.

This is my second flashlight from Olight. The other one I use is the Olight S30R III. I use each of them for a slightly different purpose. The Olight S1R is my EDC flashlight and the S30 III is my preferred flashlight for straying around in abandoned buildings and lost places. But this review is about the S1R Turbo S Baton only.

So, to begin, here are my requirements for an EDC flashlight:

  • As small as possible. Has to fit into all kinds of pockets: From pockets my Osprey Farpoint 40 backpack, to each of the 20+ pockets of my ScottseVest and even into the pocket of my Jean.
  • I need a strong clip on the flashlight so I can secure it inside any pocket and find this small thing again in any pocket.
  • As bright as possible with different brightness levels including what I call a ”low light” mode.
  • Long lasting battery. As long as physically possible
  • Battery must be chargeable inside the flashlight without even the slightest disassembly. I simply don't want to unscrew anything or fiddle around with a small cap of a charging port to be able to charge it.
  • Water resistant; not the ”scuba diving” kind of water resistant but more the ”will still work when used an hour in heavy rain” or “dropped it into a wet spot” thing.
  • Somehow attachable to other things without the need to carry additional, bulky, accessories.

It’s a small flashlight

The packaging makes the S1R Turbo S look bigger than it actually is because the bottom of the packaging contains the charging cable, clip, pouch and wrist strap.

The S1R flashlight is truly small. With a length of 2.59 inches it’s the size of my small finger and its diameter is a bit smaller than 10 (Dollar) Cent coin. It just fits in the palm of my hand. That small form factor makes it a perfect everyday carry flashlight for me.

It comes with a battery (already inside), an USB charging cable, a wrist strap that you have to fiddle through a small hole at the back of the flashlight and a carrying pouch. Here’s what you get:

What I really like is the strong magnet on the back of the S1R. With that you can simply attach the flashlight to any metal thing like a tent pole or your tripod.

The flashlight has five brightness levels, three “normal” and two turbo modes.

The brightest one is called “Turbo S” and delivers bright 900 lumen for 1.5 minutes. Then, I guess to prevent overheating, it reduces the brightness a bit to 600 lumen and it will still run for almost an hour.

To enter the turbo modes in the Olight S1R:

  • Short press the side button to turn the flashlight on
  • Double press the side button quickly to enter the first turbo mode
  • Double press the side button quickly again to enter “Turbo S” mode with 900 lumen.

It also has what I call a low light mode (Olight calls it a moon mode). In this mode you’ll get just a little light that’s great to find the keyhole, adjust something on your tripod in darkness, mount a Moment Lens in darkness and so on. Great for saving battery and just what I need.

Battery and charging

The Olight S1R Baton has a removable 550 mAh RCR123 battery that can be charged inside the case. No disassembly required. I just love that.

On the back of the flashlight is a small magnetic pin and charging plate. Just attach the magnetic charging pod of the included cable to it. The included charging cable is an USB cable so you can use an existing power adapter and even a battery pack, if you’re e.g. out in the field, to charge the flashlight.

Note that for in case charging you need to use the included RCR123 battery. Other batteries of the same model will work, but you need to remove it for charging.

It’s water resistant

Olight advertises the S1R as being water resistant up to 2m. I haven’t tested that (and probably never will) but that sounds like it will survive an hour in the rain or a drop into a wet spot.

Speaking of dropping: Olight states that the S1R will survive a drop from a height of up to 15 meters.

Final thoughts on the Olight S1R Baton

There’s not really much I can complain about; Maybe that the “Turbo S” mode that delivers 900 lumen only lasts for 1.5 minutes. But as the S1R reduces the brightness a little bit after those 1.5 minutes and still runs for almost an hour doesn’t make that an issue for me.

Other than that, the Olight S1R Baton flashlight is exactly what I was looking for. It’s a perfect addition to my EDC: small, light, powerful and easy to charge.
