Flashlight Operation & Safety Guide

Operation Instructions

Power Supply: Insert one 18650 battery (ensure correct polarity). Remove the battery to recharge.

On/Off: Press the tail-cap button to activate.

Output: Operates on a single mode, delivering a constant 5W, 310nm mid-wave UVB beam.

 

⚠️ Critical Safety Warnings

DANGER: This device emits high-energy UVB radiation. It is a professional tool, not a toy.

Eye Protection: Certified UV-blocking safety goggles are strictly mandatory during operation.

Skin Hazard: Never expose bare skin to the direct beam to prevent burns and cellular damage.

Prohibited Use: Never point the flashlight at people or animals. Keep strictly out of reach of children.

What's Included

  • UltraFire ZV-310nm UV Flashlight 
  • Rechargeable 18650 2600mAh 3.7V lithium-ion battery 
  • DX-3 Battery Charger

Engineered for the Uncompromising Professional.

Standard 365nm UVA flashlights simply don't cut it for highly specialized work. Whether you are a field geologist tracking down rare orange-red fluorescing calcite, a botanist conducting organic stress tests, or a chemical analyst isolating synthetic minerals, you require the deep penetrating power of true 310nm mid-wave UV.

Reveal What Standard UV Leaves in the Dark.

Standard UV (365nm): Dull reactions, washed-out colors, and incomplete fluorescence.

Fact: 90% of fluorescent minerals only react to shortwave UV. Stop leaving the best finds behind.

Them

UltraFire ZV-310nm

The Emitter: Our imported 5W high-power chip vs. standard 3W commercial alternatives.

The Build: CNC-machined, solid aluminum rod with hard-anodized finishing vs. cheap alloys that scratch and dent.

The Beam: High-temperature vacuum electroplated reflector for a flawless beam profile vs. uneven, mixed-wave outputs.
Title

Zero Complications. Maximum Output.

Built for immediate deployment with no frustrating menus or strobe modes.

Insert a single 18650 battery.

Click the tail switch for instant, single-mode UVB power.

Critical Safety Step: Always wear certified UV-blocking safety goggles before operation.
Title

Calibrated for the Lab, Ruggedized for the Field.

Boasting an IP54 rating and extreme wear resistance, the ZV-310nm is built to survive harsh field conditions while maintaining the strict beam consistency required for laboratory spectroscopy and chemical analysis.

Frequently Asked Questions (FAQ)

Q1: What is the difference between this 310nm flashlight and standard 365nm UV lights?

A: Standard 365nm or 395nm lights emit long-wave UVA, which is widely used for everyday tasks like checking currency or finding pet stains. The ZV-310nm emits high-energy mid-wave UVB. This specialized wavelength is strictly required for professional applications, such as exciting specific fluorescent minerals (like calcite and certain fluorites) or conducting laboratory spectroscopy.

Q2: Why does the light beam appear very faint or almost invisible in the air?

A: This is completely normal! The 254nm (shortwave UVC) and 310nm (midwave UVB) wavelengths fall largely outside the visible light spectrum detectable by the human eye. In addition, our integrated ZWB2 optical filter blocks out stray visible purple light to ensure maximum fluorescence contrast. You will not see a bright flashlight beam in open air; instead, the magic happens when the invisible UV rays strike responsive minerals and fluorescent materials in a dark room.

Q3: Why is the beam range and coverage relatively close-up compared to standard flashlights?

A: Safety is our top priority. Shortwave (254nm) and midwave (310nm) UV radiation can be hazardous to human skin and eyes at high power levels. To strictly comply with international optical safety standards and prevent accidental injury, the power output is intentionally regulated. For optimal results, use the flashlight at close range (within a few inches to a couple of feet) in a completely dark environment.

Q4: Are safety goggles really necessary?

A: Yes, absolutely. Unlike standard blacklights, mid-wave UVB radiation is harmful to human skin and eyes. Certified UV-blocking safety goggles must be worn at all times when operating the ZV-310nm. Never point the beam at bare skin, people, or animals.

Q5: What type of battery does the flashlight use?

A: The ZV-310nm is powered by a single 18650 rechargeable battery. The device operates at a working voltage of 3.7V - 4.2V. Please note that the battery must be removed from the flashlight body to be recharged.

Q6: Can I use this light for curing UV resin or finding pet urine?

A: We do not recommend it. For basic everyday tasks like resin curing or household cleaning inspections, a standard 365nm UVA light is safer and much more effective. The ZV-310nm is a purpose-built diagnostic tool engineered for scientific research and advanced mineralogy.

Q7: How durable is the flashlight for field use?

A: It is built for rugged environments. The body is CNC-machined from a solid aluminum rod and features a hard-anodized finish for superior drop and wear resistance. It also carries an IPX54 rating, meaning it is protected against dust and splashing water from any direction.

Q8: How do I know whether I need 254nm, 310nm, or 365nm?

A: Different minerals, gems, and materials react to distinct UV wavelengths:

254nm (Shortwave UVC): Essential for classic fluorescent minerals like Willemite, Calcite (Franklin type), Scheelite, and specific geological field testing.

310nm (Midwave UVB): Highly sought-after for specialized minerals, secondary uranyl minerals, and select rock species that only respond to midwave light.

365nm (Longwave UVA): The industry standard for general mineral viewing (Yooperlites, Sodalite, Fluorite), pet urine detection, amber, currency verification, and resin curing.
