A duty flashlight has to do more than look impressive on a specification sheet. It needs to activate quickly, survive rough handling, deliver dependable runtime, and provide the right beam for the task at hand.
The WUBEN X5 and WUBEN L3 take two different approaches. The X5 is a compact three-in-one tool combining white light, ultraviolet light, and a green laser. The L3 is a more traditional tactical powerhouse, offering 3,000 lumens, seven lighting modes, a larger battery, and IP68 waterproof protection.
So, which belongs among the best tactical flashlights for police duty? Let’s break it down.
WUBEN X5: A Compact Multi-Tool for Specialized Tasks
The WUBEN X5 reaches 1,300 lumens with a beam distance of around 200 meters. While it isn’t as bright as the L3, it offers several functions that the larger light doesn’t.
Its three-in-one system includes:
- A 1,300-lumen white light
- A 2W 365nm UV light
- A daylight-visible green laser
The UV light may assist with stain detection, counterfeit checking, document inspection, and other investigative tasks. The green laser has its own rear switch, allowing immediate activation without cycling through white-light modes.
That separate control is a smart touch. When seconds count, nobody wants to click through five settings just to reach the feature they need.
Why the X5 Stands Out
- Compact, flat anti-roll body
- Independent rear laser button
- Rotary dial interface
- One-lumen Moonlight mode
- Up to 200 hours in Moonlight
- Rechargeable lithium-ion battery
- AAA battery backup support
- Bidirectional pocket clip
- IP65 weather resistance
- One-meter drop protection
The X5’s battery flexibility is especially useful. Its rechargeable 1,200mAh battery handles everyday use, while commonly available AAA batteries can serve as an emergency backup.

WUBEN L3: Built for High-Output Duty Lighting
The WUBEN L3 produces up to 3,000 lumens and reaches approximately 226 meters. That’s enough output to illuminate large parking areas, building exteriors, roadways, and open spaces.
Its seven lighting modes include:
- Turbo
- High
- Medium
- Low
- Moonlight
- Strobe
- SOS
This range gives officers flexibility during searches, traffic stops, patrol work, emergency signaling, and close-range documentation.
The L3 also carries a 4,800mAh battery, providing up to 120 hours of runtime in its lowest setting. An 18W reversible USB-C port makes charging straightforward—no need to hunt for a proprietary cable after a long shift.
Why the L3 Fits Traditional Tactical Use
Its strongest features include:
- Higher 3,000-lumen output
- Long 226-meter throw
- Fast access to strobe and multiple brightness levels
- IP68 waterproof construction
- One-meter drop resistance
- Scratch- and corrosion-resistant aluminum body

Best Tactical Flashlights for Police Duty: X5 or L3?
Choose the WUBEN L3 when you need:
- Maximum white-light output
- Strong flood and distance visibility
- IP68 waterproofing
- Longer primary battery capacity
- Traditional tactical modes such as strobe and SOS
- A rugged patrol or search flashlight
Choose the WUBEN X5 when you need:
- UV inspection capability
- Instant green-laser access
- A smaller, flatter EDC form
- Rechargeable and AAA power options
- A secondary duty light for specialized tasks
- Easy pocket or vest carry
Put simply, the L3 is the stronger primary duty flashlight. The X5 makes more sense as a versatile secondary tool for inspection, signaling, and everyday carry.
What Should Officers Look for in a Duty Flashlight?
Brightness matters, but it’s only one piece of the puzzle. A reliable police flashlight should also offer:
- Simple controls under stress
- Useful sustained brightness
- Strong water and impact resistance
- A secure grip or pocket clip
- Multiple power options
- Appropriate beam distance
- Easy charging
- Fast access to low, high, or strobe modes
Departmental policies should also be checked before using laser, strobe, or UV functions during official duties.
Frequently Asked Questions
How many lumens should a police flashlight have?
A range of 1,000 to 3,000 lumens is suitable for many patrol and search tasks, provided the flashlight also offers lower modes for close-range use.
Is the WUBEN L3 waterproof?
Yes. The L3 has an IP68 rating, making it suitable for heavy rain and demanding outdoor environments.
What is the UV light on the WUBEN X5 used for?
Its 365nm UV light may help identify stains, inspect documents, and detect certain counterfeit markings.
Can the WUBEN X5 use AAA batteries?
Yes. It supports a rechargeable lithium-ion battery and AAA backup power.
Which flashlight is better for long shifts?
The L3’s larger 4,800mAh battery makes it better suited to extended primary-duty use, while the X5 works well as a compact backup or specialist light.
Conclusion
Among the best tactical flashlights for police duty, the WUBEN L3 wins on brightness, battery capacity, waterproofing, and conventional tactical performance.
The WUBEN X5 takes a different route, offering UV inspection, an independent green laser, compact carry, and flexible battery support.
For primary patrol lighting, choose the L3. For a versatile secondary tool that does more than shine white light, the X5 brings plenty to the table.
