This indispensable tool is a top choice for a wide array of users, from automotive technicians and electricians to outdoor enthusiasts, DIYers, and anyone prioritizing reliable light in an emergency.

Why Choose the Streamlight Stylus Pro USB 350/90 Lumens LED Penlight?

The Streamlight Stylus Pro USB is more than just a flashlight; it's a testament to Streamlight's commitment to delivering professional-grade illumination solutions. Engineered with precision and built for durability, this penlight addresses common pain points associated with traditional flashlights: limited battery life, the constant need for disposable batteries, inadequate brightness for detailed tasks, and bulky designs that hinder portability. The Stylus Pro USB tackles these challenges head-on, offering a highly efficient, rechargeable, and incredibly potent lighting instrument that redefines what a compact flashlight can be.

This penlight is ideally suited for:

• Professionals: Automotive mechanics, HVAC technicians, electricians, plumbers, inspectors, and maintenance personnel who require bright, focused light for intricate work in tight spaces.
• Everyday Carry (EDC) Enthusiasts: Individuals who value preparedness and seek a high-performance, compact light that easily integrates into their daily essentials.
• Outdoor Adventurers: Campers, hikers, and explorers who need a lightweight yet robust light source for navigating trails, setting up camp, or unexpected situations.
• Homeowners & DIYers: Perfect for illuminating dark corners during home repairs, finding lost items, or providing essential light during power outages.
• Emergency Preparedness: A vital component of any emergency kit, offering reliable light when conventional power sources fail.

Unmatched Performance in a Compact Design

At the core of the Streamlight Stylus Pro USB's appeal are its impressive performance metrics. Delivering a powerful 350 lumens on its high setting and a versatile 90 lumens on its low setting, this penlight provides ample illumination for a multitude of tasks. The high setting offers a broad, bright beam capable of cutting through darkness and illuminating distant objects, while the low setting is perfect for close-up work, extending battery life, or preserving night vision.

The advanced C4® LED technology ensures a consistent and intense beam, optimized for clarity and reach. This isn't just about raw lumens; it's about usable light that allows you to see details clearly, identify issues quickly, and navigate safely in challenging environments. Whether you're inspecting an engine bay, locating a wire in a dimly lit panel, or finding your way through a dark campsite, the Stylus Pro USB delivers light you can depend on.

Revolutionary USB Rechargeability: Convenience Redefined

One of the most significant advantages of the Streamlight Stylus Pro USB is its integrated micro-USB charging port. Gone are the days of fumbling for disposable batteries or specialized charging cradles. This penlight can be conveniently recharged using any standard micro-USB cable, plugging into wall adapters, car chargers, power banks, or even a laptop. This universal charging capability makes it incredibly easy to keep your light powered up and ready for action, whether you're at home, in your vehicle, or on the go.

The included 1000 mAh Lithium-Ion battery is specifically designed for long-lasting performance and thousands of recharge cycles, offering an economical and environmentally friendly alternative to traditional battery-powered flashlights. An indicator light signals charging status (red for charging, green for fully charged), providing clear feedback and preventing overcharging. This thoughtful design ensures maximum battery life and consistent performance over time.

How Long Does the Streamlight Stylus Pro USB Battery Last?

Understanding battery life is crucial for any portable device. The Streamlight Stylus Pro USB provides impressive run times relative to its compact size and powerful output:

• High (350 Lumens): Offers approximately 1.5 hours of continuous runtime, perfect for tasks requiring maximum illumination.
• Low (90 Lumens): Delivers an extended runtime of approximately 3.5 hours, ideal for less demanding tasks or when conserving power is a priority.

These run times are calculated from initial output down to 10% of the initial output, giving users a realistic expectation of performance. The intelligent power regulation ensures a consistent beam throughout the battery's discharge cycle, rather than a rapid dimming.

Built to Endure: Rugged Construction and Reliable Durability

The Streamlight Stylus Pro USB is crafted from durable, black anodized aircraft-grade aluminum. This robust material is not only lightweight but also incredibly resistant to corrosion, impacts, and general wear and tear, making it an ideal choice for tools exposed to harsh environments. The non-slip knurled grip provides a secure hold, even with wet or gloved hands.

Beyond its material composition, the penlight boasts a high level of ingress protection. With an IPX4 water-resistant rating, it is protected against splashing water from any direction, making it suitable for use in rainy conditions or environments where it might encounter splashes. It's not designed for submersion, but it can certainly handle inclement weather. Furthermore, the Stylus Pro USB is impact-resistant tested to 1 meter, meaning it can withstand accidental drops and bumps without compromising its functionality. This level of durability ensures that your investment will continue to perform reliably through years of demanding use.

Features Designed for Practicality and Ease of Use

Streamlight understands that usability is paramount, especially for tools used in fast-paced or challenging situations. The Stylus Pro USB incorporates several practical features that enhance its functionality:

• Tail Switch Operation: A simple, intuitive push-button tail switch allows for easy one-handed operation. Press fully for constant on/off, or tap lightly for momentary illumination and to cycle between high and low modes. This direct control ensures quick access to light when every second counts.
• Removable Pocket Clip: The integrated, sturdy pocket clip allows for secure attachment to shirts, pants, belts, or hats, transforming it into a hands-free light source. This feature is particularly valuable for professionals needing to keep their hands free for tasks while still illuminating their work area.
• Compact Size: Measuring just 6.15 inches (15.62 cm) in length and weighing a mere 2.0 ounces (56.7 grams), the Stylus Pro USB is designed for ultimate portability. Its pen-like form factor makes it an ideal fit for shirt pockets, tool belts, or small compartments.
• Charge Indicator: A dual-color LED indicator on the tailcap clearly shows the charging status: red for charging, green for fully charged. This eliminates guesswork and ensures your light is always ready.

Seamless Integration into Your Toolkit

For professionals, the Streamlight Stylus Pro USB isn't just an accessory; it's an essential part of their toolkit. Its slender profile allows it to reach into confined spaces where larger flashlights cannot, making it indispensable for inspections, diagnostics, and repairs in automotive engines, electrical panels, or plumbing systems. The bright, focused beam illuminates even the darkest crevices, ensuring no detail is overlooked.

For the everyday user, its unassuming size belies its powerful capabilities. It slides into a purse, backpack, or glove compartment with ease, always available for unexpected power outages, walking the dog at night, or simply finding something under the couch. Its versatility makes it a go-to light for countless situations that arise daily.
