Olight S1A Mini EDC 600 Lumens Flashlight- Users Ratings & Review

Last Updated on May 26, 2025

Being an outdoor enthusiast, I always make sure to carry a reliable flashlight, and among the countless models I’ve tested, the Olight S1A has stood out for its compact size, powerful output, and dependable design. Whether you’re heading out for a camping trip or simply want a handy light source for everyday use, this flashlight packs a punch for its size. In this detailed Olight S1A review, I’ll share my hands-on experience, break down its technical features, compare it with other popular models, and help you decide whether it’s the right everyday carry (EDC) light for you.

Why Choose an EDC Flashlight Like the Olight S1A?

If you’re searching for the best EDC flashlight, your top priority should be reliability in all situations. Flashlights like the Olight S1A are designed for people who need a lightweight, portable, and high-performing lighting tool. Whether you’re hiking, fixing your car at night, or experiencing a power outage, having a flashlight you can trust makes all the difference.

The Olight S1A may be small in form, but it delivers surprisingly strong performance. With a maximum output of 600 lumens (or 1000 lumens in its upgraded version), multiple light modes, and rugged construction, it’s the kind of flashlight that proves useful in more ways than one.

Technical Features of the Olight S1A Flashlight

This flashlight is engineered to handle outdoor challenges with ease. It’s water-resistant, drop-proof, and compact enough to fit in your pocket, making it ideal for EDC, camping, hiking, and even tactical use.

Durable Design with Outdoor Readiness

Built with Premium Aluminum Alloy

One of the most impressive aspects of the Olight S1A flashlight is its durable construction. The body is made from aircraft-grade AL6061-T6 aluminum alloy, which not only adds strength but also keeps the weight low. It’s further treated with Type-III hard anodizing to resist scratches and wear. Additionally, the blue PVD-coated stainless steel bezel and switch ring provide a stylish finish while enhancing durability.

This kind of build quality is rare in such a compact light, especially in the budget range. That’s what makes the S1A an excellent pick among other top contenders in our best AA flashlight list.

Designed for Water and Impact Resistance

The Olight S1A meets IPX8 waterproof standards, meaning it can be submerged in water up to 2 meters deep for 30 minutes. It’s also impact-resistant up to 1.5 meters, making it resilient against drops or accidental knocks—ideal for rugged environments like campsites or work sites.

Powering the S1A: Battery Options

This flashlight supports both AA batteries and 14500 rechargeable lithium-ion batteries. Here’s why that’s important:

• AA Battery: Readily available and inexpensive, but limited brightness (no Turbo mode).
• 14500 Li-ion Battery: Unlocks the full 600-lumen output and turbo features.

If you’re on the go, carrying a few AA batteries gives peace of mind. But for maximum power and performance, using a 14500 rechargeable battery is the way to go. This dual battery compatibility is one of the features that elevate the Olight S1A above other EDC lights.

Powered by Cree XM-L2 LED Technology

The heart of the Olight S1A lies in its Cree XM-L2 LED, a premium LED that delivers exceptional brightness and color accuracy. Cree has long been a leader in LED innovation, and their XM-L2 chip is known for producing powerful, cool white beams while maintaining energy efficiency.

This LED ensures you get the most lumens per watt, making the S1A incredibly bright for its size. In fact, many compact lights in the same class use lesser LED chips, but Olight consistently prioritizes performance by choosing high-end components.

Maximum Output and Beam Distance

When powered by a 14500 rechargeable battery, the Olight S1A flashlight can hit up to 600 lumens in turbo mode. That’s extremely impressive for a flashlight that’s just over 3 inches long. In fact, this light can throw a beam up to 118 meters, which is more than enough for most daily and emergency tasks.

If you upgrade to the S1A II version, the output boosts to 1000 lumens with a beam distance of 135 meters. Whether you’re walking your dog at night or looking for something in the attic, this light provides excellent visibility and control.

PMMA TIR Lens: Focused, Controlled Illumination

Instead of using an older reflector design, the Olight S1A employs a PMMA Total Internal Reflection (TIR) lens. This lens helps to focus and shape the light more precisely, creating a clean and even beam with minimal spill. It provides:

• A soft, diffused central hotspot
• Minimal light loss around the edges
• Better control for both close-up and medium-range tasks

Unlike traditional reflectors, this lens design doesn’t require a top glass layer, making the light more efficient and compact.

Lighting Modes and Runtime

One of the standout features of the S1A is its versatile light output modes. It offers a variety of levels to suit different scenarios:

Mode	Brightness	Runtime	Best For
Moonlight	0.5 Lumens	Up to 15 days	Reading maps, preserving night vision
Low	5 Lumens	40 hours	Tent lighting, short walks
Medium	50 Lumens	10 hours	General use, backup light
High	220 Lumens	1 hour	Outdoor navigation, indoor power outages
Turbo	600 Lumens (14500 only)	~3 minutes (step down after)	Blinding brightness, large area lighting
Strobe	10Hz	Variable	Self-defense, signaling

Note: Using an AA battery limits the flashlight’s brightness and disables Turbo mode. To experience the full potential, always use a 14500 rechargeable battery.

This wide range of brightness levels makes the S1A one of the most versatile lights in its class. Whether you’re looking for a soft glow or an intense beam, the S1A has you covered.

Runtime Optimization and Battery Efficiency

In Eco (moonlight) mode, this flashlight can run continuously for up to 15 days on a single battery. That’s an incredible feature for long trips where battery conservation is key. You’ll find it especially useful during emergencies or extended outdoor activities.

For comparison, lights like the Outlite A100 may be brighter in short bursts but lack the efficient low modes that Olight offers.

Ease of Use and Practical Design

Simple and Secure Side Switch Operation

A good flashlight is not only about brightness—it’s also about how easy it is to operate. The Olight S1A flashlight features a side switch, allowing for smooth operation with just one hand. This switch is conveniently located and requires minimal effort to press, even in the dark or while wearing gloves.

The interface is intuitive:

• Single click to turn on/off
• Hold to cycle through brightness levels (Low > Medium > High)
• Double-click to activate Turbo mode
• Triple-click to enable Strobe

You can quickly memorize this control scheme, which is essential during emergencies when time matters most.

The switch is reinforced with a rubber cover and sealed with an O-ring, helping protect against water and dust entry—contributing to its IPX8 waterproof rating.

Lightweight and Highly Portable

At just around 3 inches long and weighing only 46 grams (without battery), the S1A is one of the most lightweight flashlights you’ll ever use. It easily slips into a:

• Shirt or pants pocket
• Purse or backpack
• Glove box or tool pouch

Unlike bulky tactical flashlights, the S1A fits comfortably into your everyday lifestyle. It’s the kind of tool you can forget you’re even carrying—until you need it. That’s why many people also rank it among the top picks in our best keychain flashlight guide.

Pocket Clip and Lanyard for Extra Convenience

To ensure that you can carry the flashlight your way, Olight includes both a removable pocket clip and a lanyard. This clip is sturdy and deep enough for secure pocket carry, while the lanyard lets you attach the light to your wrist, belt loop, or backpack.

Whether you’re commuting, hiking, or biking, these carrying options ensure your flashlight stays accessible and secure. This is especially useful when your hands are occupied with other gear or tasks.

Durability That Goes the Distance

Built to Withstand Harsh Environments

The Olight S1A is not just another sleek gadget—it’s built for real-world use. The durable 6061-T6 aluminum alloy body with hard anodized coating resists scratches, corrosion, and impacts. Whether you drop it on rocky terrain or use it in rainy conditions, it keeps functioning like new.

Its impact resistance of 1.5 meters means it can survive accidental drops from your hand or a pocket. The flashlight also maintains full functionality after being submerged in up to 2 meters of water for 30 minutes, thanks to its IPX8 waterproof rating.

Ideal for a Wide Range of Users

The S1A is great for:

• Campers & Hikers – Compact, reliable, and bright enough for trail visibility
• Mechanics & DIYers – Precision lighting for small, tight spaces
• Commuters – Safety during low-light travel or power outages
• Parents – Nighttime use without disturbing sleeping children
• Security & Self-Defense – Strobe mode and Turbo for disorienting threats

Olight S1A vs S2R: Side-by-Side Comparison

If you’re considering the Olight S1A, you might also want to compare it with other EDC lights in Olight’s lineup—especially the more powerful S2R Baton II. Below is a detailed comparison between the different versions of the S1A and S2R lights to help you make the best decision based on size, power, and budget.

Key Differences to Consider

• Battery Size: The S2R series uses a larger 18650 battery, which allows for longer runtimes and higher output, but adds weight and size.

• Portability: The S1A wins when it comes to pocket-friendliness and travel convenience. It’s the more compact option.
• Brightness and Runtime: The S2R II offers longer runtimes and slightly higher brightness, making it better for professional or tactical use.
