Convoy S2+ 365nm UV Flashlight

The Convoy S2+ 365nm UV Flashlight consistently emerges as a top contender in the UV flashlight market, praised for its exceptional balance of performance and affordability. This flashlight is powered by a Nichia 365nm UV LED, which is widely regarded for delivering a true ultraviolet wavelength that causes strong fluorescence in minerals, stains, and security features without the excessive purple glow seen in cheaper 395nm models. One of its standout features is the compatibility with a ZWB2 filter, a dark glass lens that effectively blocks out virtually all visible light, leaving only pure UV to illuminate targets. This filter is available for just a few dollars, making it an incredibly cost-effective upgrade that dramatically improves the flashlight's performance for serious applications like gemstone hunting or counterfeit detection. The Convoy S2+ uses a standard 18650 lithium-ion battery, providing a good balance between size and runtime. Users appreciate the modular design, which allows for easy disassembly and modification, a feature that has made it a favorite among flashlight enthusiasts and modders. However, the beam is somewhat narrow, which means it excels at focusing on specific targets rather than illuminating large areas. While its build quality is solid and functional, it lacks the high-end anodizing and impact resistance of more expensive tactical lights. Despite these minor drawbacks, the Convoy S2+ remains a top recommendation for anyone needing a reliable, high-performance UV light without spending a fortune. Its performance in tests for detecting paint anomalies, verifying currency, and fluorescing gemstones like Yooperlites and Anyolite has been consistently rated as above average, placing it among the best performers in its class. For the price, it delivers an unbeatable combination of wavelength purity, filter compatibility, and user-serviceable design.
