Multi-Colour LED Keychain Flashlight

The Armytek Crystal Pro UV Red combines white, red, green, blue and 365 nm ultraviolet light in a single rechargeable body. It serves as a headlamp, everyday-carry light, keychain beacon or clip-on signal for outdoor and professional tasks. A soft elastic headband and wear-resistant plastic rings provide multiple mounting options. The 180° beam angle suits close-range work.

Thermals Noise and Power

The flashlight runs directly from any USB-C power source without flickering, so heat and noise stay minimal during extended use. An integrated Li-Pol battery delivers up to 50 days of runtime on the lowest setting. Constant-current drive keeps output steady across all colour modes. No active cooling is required.

365 nm Ultraviolet Output

The 365 nm UV emitter reveals hidden security features, fluorescent minerals and biological traces that visible light cannot show. White, red, green and blue channels add 200, 35, 100 and 20 lumens respectively for navigation, map reading and signalling. Buyers who need higher UV power or a narrower beam should consider other tools.

Questions about this item

How do I install the headband and what step do people often miss?

Thread the soft elastic headband through the body slots and ensure the 180° beam angle faces forward for close-range use; the common miss is mounting it backward so the light points away from the task.

What maintenance will the built-in Li-Pol battery need later?

Recharge via USB-C when output drops; the cell is sealed and not user-replaceable, so plan on full replacement once it no longer holds a charge after many cycles.

Which limit appears first during sustained use on the 200 lm white mode?

The 200-lumen white setting drains the internal battery fastest, so runtime ends well before the 50-day minimum-brightness figure; heat is managed by the constant-light design.
