Core Overview
Built around a 7W UV-365 LED array with multi-bead configuration for uniform beam distribution, the Z16 delivers consistent, artifact-free UV output with a 25-meter effective range. Powered by a 21700/3000mAh lithium battery (compatible with 18650 and 3×AAA via included adapter options), the Z16 achieves approximately 6 hours of runtime with full-charge time of approximately 6 hours via Type-C USB. The aluminum alloy body with purple accent detailing, IP44 environmental protection, comprehensive safety electronics, and built-in power bank output make the Z16 the definitive tool for professionals who cannot compromise on UV inspection quality.

Key Product Advantages
- True 365nm UV with Black Lens Filter — Zero Visible Light Contamination
The Z16’s 365nm wavelength combined with the integrated black (Wood’s glass) filter absorbs virtually all visible light emitted by the UV LED, outputting a nearly invisible beam. This is the critical advantage over 395nm UV lights: at 395nm, the eye sees a visible purple glow that masks and dilutes fluorescence on the target surface. At 365nm with filtering, only the fluorescence response is visible — delivering dramatically higher contrast and enabling detection of subtle fluorescence signatures that 395nm lights simply cannot reveal.
- Multi-Bead LED Array — Uniform, Artifact-Free UV Beam
Rather than a single high-power UV LED that creates a hotspot at the beam center, the Z16 employs a multi-bead LED array that spreads UV output evenly across the illumination field. This eliminates the “bright center, dim edges” pattern that can cause inspectors to miss fluorescence at the periphery of the beam, and provides consistent, reproducible illumination for photography and documentation of fluorescence findings.
- Triple Battery Compatibility — 21700 / 18650 / 3×AAA
The Z16’s battery compartment is engineered to accept a 21700 lithium cell (3000mAh, included), a standard 18650 lithium cell, or three AAA alkaline batteries — the widest battery compatibility in the SUPERFIRE UV flashlight range. The 21700 provides maximum runtime (approximately 6 hours), while 18650 and AAA compatibility ensure the Z16 remains operational even when the primary battery is unavailable — a critical consideration for field investigators and mobile inspection teams.
- Built-In Power Bank with Comprehensive Safety Electronics
A USB output port converts the Z16 into an emergency power bank for charging mobile devices, GPS units, or communication equipment in the field. The comprehensive safety electronics suite includes overcharge protection, over-discharge protection, low-voltage cutoff, low-voltage warning, and reverse polarity protection — ensuring the battery and electronics remain protected through all operating and charging conditions.
- Professional-Grade Aluminum Body with IP44 Protection
The Z16’s aluminum alloy body with signature purple accent band delivers both professional aesthetics and structural integrity, tested to 1-meter drop resistance. IP44 environmental sealing protects against dust particles larger than 1mm and water splashes from any direction, making the Z16 suitable for field inspection work in industrial environments, outdoor crime scenes, and less-than-pristine inspection conditions where a laboratory-grade tool wouldn’t survive.

FAQ
What is the practical difference between 365nm and 395nm UV for inspection work?
The 365nm wavelength is shorter and higher-energy than 395nm, and critically, it sits almost entirely outside the visible spectrum when paired with a black filter lens. This means: (1) the UV beam itself is nearly invisible, eliminating the purple “wash” that dilutes fluorescence contrast; (2) 365nm excites a different subset of fluorescent materials — some substances that glow strongly under 365nm show minimal response under 395nm, and vice versa; (3) for professional applications like forensic examination and gemological grading, 365nm filtered UV is the industry standard because it reveals fluorescence signatures that 395nm lights obscure or fail to excite entirely.
Why is the black lens filter important, and can it be removed?
The black filter (visible-light blocking filter, also known as Wood’s glass) is critical because UV LEDs naturally emit a small amount of visible purple/blue light alongside the UV output. Without filtering, this visible spill significantly reduces fluorescence contrast — you’re seeing both the purple light AND the fluorescence simultaneously, which compresses the visible dynamic range. With the filter, nearly all visible light is blocked, so when you shine the Z16 on a surface, you see ONLY the fluorescence response against a dark background. The filter is an integral part of the Z16’s optical system and is not designed to be removed.
How does the triple battery compatibility work in practice?
The Z16’s battery tube accepts 21700 cells (included) for maximum capacity and runtime. For 18650 compatibility, use the included adapter sleeve that fills the diameter difference between the 21700 tube and the narrower 18650 cell. For 3×AAA operation, an AAA battery carrier (sold separately or included in some kit configurations) holds three AAA cells in series to match the voltage requirement. This compatibility ensures the Z16 remains operational in field conditions where the primary 21700 battery may not be rechargeable and replacement cells are the only option.
Can the Z16 be used for gemstone and diamond authentication?
Yes, the Z16’s 365nm filtered UV output is ideal for gemological fluorescence examination. Many gemstones exhibit characteristic fluorescence responses under long-wave UV (365nm): diamonds commonly fluoresce blue, rubies glow intense red, certain sapphires show orange or red fluorescence, and amber exhibits blue-white to green fluorescence. These fluorescence signatures can aid in identification, natural vs. synthetic differentiation, and detection of treatments or enhancements. Note that professional gemological grading should be performed alongside other diagnostic tools — UV fluorescence is one indicator among many.
What is the effective working distance for the Z16 during inspection?
The Z16’s 25-meter maximum beam range represents the distance at which UV output remains detectable, but effective inspection distance depends on the material being examined and ambient light conditions. For optimal fluorescence excitation: currency and documents: 5–15cm; hotel/cleaning inspection: 10–30cm; mineral specimens: 15–50cm; larger surface area scanning (floors, walls): 30cm–1m. The UV beam is most intense at close range, and fluorescence brightness diminishes with distance. For best results, work in as dark an environment as practical — UV fluorescence contrast is greatest against a dark or low-ambient-light background.
