OLIGHT Baton 4 Pro Flashlight
Olight Baton 4 Pro Flashlight Review
While the official launch isn’t until April 15, 2026, I’ve been carrying and testing a unit of the new OLIGHT Baton 4 Pro Flashlight for approximately a month. As an everyday carry (EDC) tool, a reliable flashlight is indispensable on the job site or for home inspections. Based on my hands-on time with it, this model successfully prioritizes high lumen output in a compact form factor, while introducing highly practical updates to its charging interface and everyday usability.
Here is a practical breakdown of how the Baton 4 Pro performs in the field.
Design, Size, and Carry Options
The physical dimensions are 111mm long by 23mm wide, with a total weight of 115g. So, in imperial terms, the flashlight is roughly 4.37 inches long, just under an inch wide, and weighs just over a quarter of a pound (about 4 ounces).
In practice, I’ve found this size and weight to be perfect for front pocket carry. It doesn’t add unnecessary bulk or drag down your work pants.
OLIGHT Baton 4 Pro Flashlight | Durable Construction
TheOLIGHT Baton 4 Pro Flashlight build quality is rugged. The housing is aerospace-grade aluminum with a hard-anodized finish. The grip portion features an aggressive knurling that is durable and provides an excellent, secure grip, even if your hands are wet or you are wearing work gloves. Additionally, the flashlight features a robust, two-way pocket clip that gives you two distinct carry options: a low-profile deep carry for securing it out of the way, and a higher, more visible position for quicker access.
The OLIGHT Baton 4 Pro Flashlight has an IPX8 rating. Ever wonder what that means?
“IP” stands for Ingress Protection, which is the international standard for how well a device keeps out dust and liquids.
-
The “X” means it wasn’t formally graded for solid particle (dust) resistance. However, because it is a tightly sealed, O-ring-protected aluminum cylinder, drywall dust and sawdust aren’t getting inside.
-
The “8” is the highest standard water resistance score typically given to flashlights. Olight tests these specific models to survive being continuously submerged in up to 2 meters (about 6.5 feet) of water for 30 minutes.
For a contractor, plumber, or home inspector, this rating guarantees that the light isn’t just “splash-proof.” It will easily survive the worst weather and jobsite conditions you can throw at it:
If you drop it into a sump pump pit or a foot of standing water in a basement, you can fish it out, wipe it off, and keep working.
Pro Tip: If the light takes a dunk, shake out the USB charging port and let it air dry completely before you hook it up to a power bank or wall charger to avoid a short circuit at the connection point.
OLIGHT Baton 4 Pro Flashlight | Output Performance
In terms of performance, this light is exceptionally bright. It delivers a maximum output of 1600 lumens and a beam throw of 200 meters. For a light of this size, it provides more than enough illumination for inspecting dark crawlspaces or lighting up a backyard. It is important to note that the peak 1600-lumen output is typically a “Turbo” burst mode used for quick illumination, while sustained, continuous work relies on its lower, heat-manageable settings.
OLIGHT Baton 4 Pro Flashlight | Charging Interface
Olight has historically relied on proprietary magnetic charging cables. While convenient on a workbench, it becomes a liability if you lose the cable in the field. The Baton 4 Pro introduces a dual-charging system that retains the magnetic charging capability but integrates a rotating USB-C port. This means you can now charge it in your work truck or off a standard power bank without needing Olight-specific gear.
Having tested this on the go, I really appreciate this upgrade. If the proprietary cable is misplaced or left at the shop, you can easily “top off” the light using a standard USB-C cable plugged into a work truck, laptop, or power bank.
You can expect the following charge times with th OLIGHT Baton 4 Pro Flashlight :
- USB-C Charging: 3.5 hours
- Magnetic Charging: 4.5 hours
OLIGHT Baton 4 Pro Flashlight | Dual Switch Ergonomics
I am a big fan of the OLIGHT Baton 4 Pro Flashlight dual-switch button design, which manages operation through two separate switches to accommodate different grips and working conditions:
- Rear Tactical Tail Switch: Provides quick, tactical activation when holding the light in an overhand grip. A plus for security work, inspection or tactical use.
- Side Switch: An enlarged metal button for standard, underhand use.
The side switch also incorporates battery level and brightness mode indicators using laser micro-perforations through the metal housing. This design choice eliminates traditional plastic or rubber indicator windows, which are prone to scratching, cracking, or clouding up with drywall dust and grime in harsh work environments.

Olight Baton 4 Light Output | 600 Lumens
The OLIGHT Baton 4 Pro Flashlight boasts a peak output of 1,600 lumens. To put that in perspective, a standard 60-watt incandescent household bulb produces about 800 lumens.
However, it is crucial to understand that 1,600 lumens is a “Turbo” mode. You will not get 1,600 lumens continuously for hours. In a flashlight this small, pushing that much power generates a massive amount of heat. The light will run at this peak output for a minute or two before a built-in thermal sensor automatically ramps the brightness down to a lower level (typically around 600 lumens) to prevent the LED and battery from overheating.
For 90% of my work, I used the Baton 4 Pro on its High setting, which provide plenty of usable light.
Distance and Throw | 200 Meters
The OLIGHT Baton 4 Pro Flashlight has a rated beam distance, or “throw,” of 200 meters.
Flashlights generally fall into two categories: “throwers” (tight, laser-like beams that reach far) and “flooders” (wide beams that light up the immediate area). At 200 meters, the Baton 4 Pro sits comfortably in the middle. It has enough reach to inspect a roofline from the ground, but it isn’t a dedicated spotlight. It is designed as a general-purpose utility light. I found it struck a nice balance between long-distance beam reach and close-up visibility.
OLIGHT Baton 4 Pro Flashlight | Runtime
Because this light uses a high-capacity 18650 lithium-ion battery, the runtime varies drastically depending on the mode you select:
- Turbo (1,600 lumens): Lasts only 1-2 minutes before automatically stepping down to protect the internal components.
- High (600 lumens): Imm seeing approximately 2 to 2.5 hours of continuous use.
- Medium (60-100 lumens): This is the sweet spot for up-close work like wiring a circuit panel or working in a dark closet. At this level, the light can easily run for 8- to 12-hours.
- Moonlight (0.5 lumens): Used for reading blueprints, walking or finding keyholes without ruining your night vision. This ultra-low mode can run continuously for weeks, which I found impressive!
- Stobe Olight
Beam Pattern | TIR Optic
Instead of a traditional deep, mirrored reflector, the Baton series uses a TIR (Total Internal Reflection) optic—a specialized plastic lens that captures and focuses the light.
Practically speaking, a TIR optic creates a very distinct beam pattern. It produces a large, smooth “hotspot” in the center, with a very gradual fade into the “spill” (the wider, dimmer ring of surrounding light). This is ideal for an everyday carry work light because it eliminates harsh rings or shadows in the beam, providing a clean, even wash of light over your immediate work area.
Light Color (Temperature)
Flashlight LEDs generally come in different color temperatures, measured in Kelvin (K). Olight typically offers models in two variations, and it is important to know the practical difference:
- Cool White (CW – approx. 6000K to 6500K): This has a slightly bluish tint. It looks brighter to the human eye and allows the flashlight to hit that maximum 1,600-lumen rating. However, cool white light tends to wash out colors, making objects look flat and harsh.
- Neutral White (NW – approx. 4000K to 5000K): This mimics natural afternoon sunlight. While it might measure slightly lower in raw lumens (e.g., yielding 1,500 lumens instead of 1,600), it provides much better color rendering.
Pro Tip: If you are an electrician or HVAC tech trying to distinguish between a faded white, gray, or yellow wire in a dark, dusty basement, a Neutral White emitter is far superior because it won’t wash out the subtle color differences. If you just need maximum blinding power for security or outdoor property walks, Cool White is the way to go.
OLIGHT Baton 4 Pro Flashlight | Proprietary 18650 Battery Design
Olight uses a proprietary 18650 battery, offering between 3200mAh and 3500mAh of capacity, and allowing its dual-charging feature. A standard 18650 battery has a positive terminal on one end and a negative terminal on the other. Olight’s custom 18650 has both the positive and negative contacts located on the same end, allowing for their dual charging options.
I always like having a backup battery, so I’m guessing some of you might be wondering what would happen if you were to buy a second off-the-shelf 18650 battery?
A standard 18650 battery will result in the following:
- Loss of “In-Body” Charging: The flashlight’s internal charging mechanism will not recognize the standard battery. You completely lose the ability to use the magnetic base or the USB-C port, defeating one of the best features of the tool.
- Fit and Contact Issues: Because Olight alters the contact points, a standard flat-top or button-top 18650 often won’t make a proper connection, meaning the light might not turn on at all.
- Risk of Shorting: Inserting standard batteries into Olight’s uniquely wired battery tube could possibly cause a short circuit.
Pro Tip: If you need a backup battery, you should purchase an official OEM replacement directly from Olight.
