Let’s Dive into Streamlight Stylus Pro USB Ultraviolet Penlight
The Streamlight Stylus Pro USB Ultraviolet Penlight is a sleek, compact, and USB rechargeable penlight designed for a variety of detection tasks. Manufactured by Streamlight, this penlight features an ultraviolet (UV) LED ideal for detecting engine or HVAC leaks, identifying fraudulent documents, and even assisting in forensic investigations. I’ve been in the outdoor and tactical gear field for over a decade, and the ability to quickly and discreetly identify substances has always been a need; this seemed like a professional tool that could solve that need effectively.
I’d been searching for a reliable, pocket-sized UV light for inspecting used gear purchases for signs of contamination and verifying currency. A standard flashlight wouldn’t do the trick. I had considered larger, more powerful UV lights, but their bulk made them impractical for everyday carry.
Upon unboxing, I was immediately struck by the Streamlight Stylus Pro USB Ultraviolet Penlight‘s slim profile and lightweight design. The aluminum body felt sturdy and well-made, and the pocket clip seemed durable enough to withstand daily use. Initial impressions were positive.
I briefly considered the Nitecore MT06MD and the ThruNite Ti3 as alternative options. Ultimately, the Streamlight Stylus Pro USB Ultraviolet Penlight won out due to Streamlight’s reputation for reliability and the convenience of USB charging. I was excited to test its capabilities in real-world scenarios.
Real-World Testing: Putting Streamlight Stylus Pro USB Ultraviolet Penlight to the Test
First Use Experience
My first test involved using the Streamlight Stylus Pro USB Ultraviolet Penlight to check for refrigerant leaks in my car’s AC system. I shined the light around the compressor and hose connections in a dimly lit garage. Immediately, traces of UV dye, previously added to the system, glowed brightly, revealing a slow leak I hadn’t been able to detect with the naked eye.
The penlight also proved useful during a recent camping trip. While not its primary intended use, I tested its water resistance in a light rain shower; the IPX4 water resistance rating held up well. There were no functional issues after being exposed to the moisture.
Using the penlight was intuitive and required no learning curve. The tail switch provided easy one-handed operation, and the focused beam allowed for precise examination of surfaces. I was impressed by the intensity of the UV light, especially given the penlight’s small size.
Extended Use & Reliability
After several months of regular use, the Streamlight Stylus Pro USB Ultraviolet Penlight has proven to be a reliable and durable tool. I’ve carried it daily in my pocket, and the aluminum body has held up well to minor bumps and scratches. There are no significant signs of wear and tear.
Maintenance has been minimal. Periodically wiping the lens with a clean cloth is all that’s required. The USB charging port remains secure and functions flawlessly. I also tested the impact resistance and it held up to a 1 meter drop as advertised.
Compared to previous UV lights I’ve used, the Streamlight Stylus Pro USB Ultraviolet Penlight stands out for its compact size, ease of use, and consistent performance. It’s a significant improvement over bulkier, less reliable options.
