The ETENWOLF CL5 is a 2-in-1 camping lantern and flashlight distinguished by its 365 nm UV-A mode — a feature unique to the CL5 within the ETENWOLF CL series. Built on a 5,000 mAh / 18.5 Wh Tianpeng cell, the CL5 delivers over 1,000 lumens in both lantern and long-range torch modes, reaches a beam distance of over 100 metres, and weighs just 205 g — the lightest unit in the series. Certified to CE, FCC, UN38.3, and RoHS standards with formal report numbers issued, the CL5 is targeted at campers, travellers, and anyone who benefits from ultraviolet verification capability in a compact form factor. Launch is scheduled for September 2025.

UV Mode Explained — 365 nm UV-A
The CL5 is the only model in the ETENWOLF CL series equipped with an ultraviolet LED. Operating at 365 nm, it falls in the UV-A band — the same range used in professional black-light applications. At this wavelength, the UV output is invisible to the human eye but causes fluorescent materials to emit visible light.
Practical applications include:
| Application | How It Works |
|---|---|
| Banknote and document verification | Security inks in most currencies fluoresce under 365 nm UV, allowing quick counterfeit checks |
| Fluorescent stain detection | Biological stains, pet urine, and certain adhesive residues fluoresce brightly under 365 nm UV in darkness |
| Scorpion detection | Scorpion exoskeletons contain fluorescent compounds that glow bright green under 365 nm UV — useful in desert camping environments |
| Mineral and gemstone inspection | Many minerals fluoresce distinctive colours under 365 nm UV light |
Safety note: Do not stare directly into the UV LED or aim it at other people’s eyes. Prolonged UV-A exposure can cause eye irritation and cumulative corneal damage. Use the UV mode in short, purposeful bursts. Do not use the UV mode on the skin repeatedly or for extended periods.
Lighting Modes
| Mode | Description |
|---|---|
| Camp Lantern | 360-degree ambient output at >1,000 lm peak for campsite and group lighting |
| Long-Range Torch | Focused beam at >1,000 lm reaching over 100 m for trail navigation and search tasks |
| SOS | International distress signal flash pattern for emergency situations |
| UV (365 nm) | Ultraviolet-A emission for fluorescence detection, scorpion detection, and document verification |
| Strobe | Rapid-flash output for visibility and signalling |
| Red Bug Repellent | Red LED wavelength to discourage insects; less attractive to flying insects than white light |

Frequently Asked Questions
What is the CL5 UV mode used for?
The 365 nm UV-A mode on the CL5 causes fluorescent materials to emit visible light. Common practical uses include verifying currency and documents (security inks fluoresce under 365 nm UV), detecting pet urine and biological stains in darkness, spotting scorpions in desert camping environments (their exoskeletons fluoresce bright green), and inspecting minerals or gemstones. The UV mode operates as a dedicated mode separate from all white-light and red-light settings.
How does the CL5 differ from the CL6?
The CL5 and CL6 share the same 5,000 mAh / 18.5 Wh battery and 10 W PD charging. The CL5 is lighter (205 g vs 259 g) and includes the unique 365 nm UV mode. The CL6 does not have UV capability but adds a bottom hook for dual-side mounting — both side and bottom positions — which is useful for hanging overhead inside tents. The CL6 also has a slightly lower peak lantern output (over 700 lm) compared to the CL5 (over 1,000 lm).
What certifications does the CL5 have?
The CL5 holds CE (WTH26H01027992E), FCC (WTH26H01027995E), UN38.3 battery transport certification (NO.1123060543), RoHS (WTH26X01027993C), and IPX5 waterproof certification (WTH25H10275786P). All five certifications are from independent third-party laboratories and their report numbers are published for transparency.
How long does the CL5 run on a full charge?
Runtime depends on the active mode and brightness level selected. The 5,000 mAh / 18.5 Wh battery supports multi-hour operation; detailed per-mode runtime tables will be published on the official product page at launch in September 2025. At low brightness settings in lantern mode, runtime is significantly extended. The UV mode and strobe mode draw lower average current than maximum-brightness white light.
Is the CL5 UV safe for eyes?
The CL5 UV LED operates at 365 nm UV-A. Direct, prolonged exposure to UV-A can cause eye irritation and cumulative damage to the cornea and lens. Do not stare directly into the UV LED, do not aim the UV beam at other people’s faces, and avoid extended skin exposure. Use the UV mode in short bursts for specific tasks such as document verification or stain detection. Children should be supervised when using the UV mode. The UV output on the CL5 is within standard UV-A flashlight levels and is not classified as a hazardous laser device.
