HQRP 21 LED Blacklight For Uranium Glass

The HQRP Professional 21 LED Blacklight operates in the 380-385 nm range and uses 21 LEDs to deliver a steady ultraviolet glow. It is powered by three AAA batteries (not included), making it a compact, portable choice for field checks and quick inspections of glowing glass. The 380 nm spectrum is commonly effective for revealing yellow-green fluorescence typical of uranium glass and Vaseline glass. This model is well-suited for collectors and testers who want a simple, reliable tool without frequent battery changes.
In practice, this flashlight provides broad coverage suitable for scanning entire glass pieces or patches on a display. It also supports broader uses such as currency checks and basic security tests, while a range of other UV-driven tasks—like art forgery tests and pet-stain detection—benefit from its consistent output. Users should note that battery quality directly impacts brightness and runtime, so fresh or high-quality AAA cells are recommended for best results.
HQRP 3W 365nm Blacklight For Rocks

The HQRP 365 nm, 3W blacklight is a compact, aluminum-bodied option designed for more intense UV work. It runs on one AA battery (not included) and offers two beams—flood for broad area illumination and a focused spot beam for inspection of small fluorescing areas. The 365 nm wavelength is widely used for detecting fluorescence in minerals and glass, including uranium-infused items, and is a dependable choice for fieldwork or hobby projects where a higher-intensity beam is beneficial.
This model emphasizes portability and efficiency, making it a solid pick for quick UV checks on rocks, minerals, and Vaseline glass. Its single-battery design favors long sessions without frequent battery swaps, though brightness and runtime depend on battery quality. While not a feature-heavy model, its straightforward operation and rugged build are appealing for users who want reliable performance without extra complexity.
DARKBEAM 395nm Mini UV Flashlight

This compact flashlight pairs a powerful 395 nm UV beam with a USB-C rechargeable design. boasting up to 10W of output, it delivers strong fluorescence for uranium glass, Vaseline glass, and other UV-reactive materials. A built-in power indicator helps manage charge levels, and the included detachable clip makes one-handed use easy for pocket storage during fieldwork. The device is slim enough to carry in a pocket or toolkit, yet bright enough to reveal subtle glow on UV-reactive glass and resins.
In use, the 395 nm wavelength is well-known for reliably revealing fluorescence in a wide range of glass types and detectors. The safety note remains important: avoid direct eye exposure and never look directly into the UV light for extended periods. Its USB-C rechargeability reduces the need for frequent battery replacements, adding to its convenience for hobbyists and professionals alike.
UV Flashlight Black Light USB Rechargeable 395nm Mini

The UV Flashlight by VMTENMV focuses on 395 nm with a compact, USB-C rechargeable design. Delivering up to 10W of power and a high radiant intensity, this model is designed for portability and quick checks of uranium glass and related fluorescence. A metal or aluminum body helps with heat management, while the included USB-C charging cable ensures simple recharging from power banks, laptops, or adapters. The device is described as easy to operate with one hand, a helpful feature for field inspections and multitasking tasks around display cabinets or labs.
Users should observe the warning not to unscrew the flashlight head, which can stop proper operation. The product’s durable construction and rechargeable design make it a practical choice for those who need a reliable, everyday UV tool for glass detection and resin work, with the added benefit of compact travel size.
DARKBEAM 365nm/395nm Dual Pack

The DARKBEAM dual-pack bundles 365 nm and 395 nm UV flashlights, each featuring a 10W LED and robust 1300 mW radiant intensity. This dual-wavelength setup lets users switch between 365 nm for more subtle fluorescence and 395 nm for brighter, more visible glow, depending on the material under inspection. A hard-wearing black filter on the 365 nm beam reduces visible purple light and improves detection accuracy for uranium glass and related fluorescents. USB-C charging provides convenient power management for longer sessions.
Compared with single-wavelength options, this dual pack offers flexibility for varied glass types and environmental lighting. The design emphasizes durability and portability, with the compact form ensuring it fits in a pocket or tool bag. While it may require a bit more setup to switch wavelengths, the payoff is a broader detection capability for uranium and Vaseline glass testing, as well as resin and resin-embedded materials.
Buying Guide
Key purchase considerations center on wavelength, brightness, power source, and ergonomics. For uranium glass, 365 nm and 395 nm are the most commonly effective wavelengths. A single-wavelength unit is often lighter and simpler to operate, while a dual-wavelength setup provides greater versatility across glass types and detection scenarios. The brightness and beam pattern—whether flood or spot—affect how quickly you can scan large surfaces or target specific features.
Battery life and charging are practical priorities. USB-C rechargeable models reduce the need to buy batteries, and higher-wattage LEDs (10W vs 3W) typically deliver stronger, more consistent fluorescence. If you frequently check displays or cabinets, a compact, clip-enabled design supports one-handed use and easy access. Durability matters too; aluminum or metal housings typically offer better heat dissipation and longer life in field conditions.
Safety and usage guidelines should be followed. Do not stare directly into UV light and use protective eyewear when possible. Avoid prolonged exposure to skin and ensure you operate in well-ventilated areas. Different glass types react to different wavelengths, so consider having both 365 nm and 395 nm options if you regularly inspect uranium glass, Vaseline glass, Depression glass, or related materials.
Practical setup tips: start with the 365 nm beam when you’re uncertain about fluorescence strength, then switch to 395 nm for a stronger reveal on suspected pieces. For field checks, prefer compact, USB-C rechargeable units with a good balance of brightness and runtime. If you work with fragile or small glass components, a dual-pack solution can reduce the need to swap tools mid-inspection. Finally, store your devices in protective cases to maintain battery and LED longevity.
