Compact multi flashlight

The Armytek Crystal Pro Grey is a rechargeable LED keychain flashlight and lantern designed for everyday carry and cycling use. Its translucent matt polycarbonate body creates a fully luminous surface that produces a wide flood beam suitable for close-range backlighting or as a light marker. The single-button interface allows quick switching between white and red light modes with a double click. It suits commuters, cyclists and outdoor users who want a lightweight, multi-function light source.

Thermals noise and power

The built-in 600 mAh Li-Pol battery charges via any Micro USB cable with colour indication of the charging process. The robust Micro USB socket and IP67 rating provide reliable protection from dust and submersion at 1 metre for 30 minutes. The housing withstands falls from up to 10 metres, ensuring durability during daily transport or bike mounting. No active cooling is required and the light operates silently in all modes.

Upgrade from single colour lights

This model replaces basic keychain lights that offer only white output by adding 30 lumen red light and a 43 lumen brake light function triggered by a built-in 3D accelerometer. The brake light activates automatically during bicycle deceleration, while an included mount secures the flashlight to the bike. It is not for buyers who need a focused long-throw beam or higher white output than 220 lumens.

Questions about this item

How do I charge the built-in 600 mAh battery and what is the common mistake?

Plug any Micro USB cable into the robust socket; the body shows color indication while charging. The step people miss is ensuring the port is fully seated so the indicator lights.

What ongoing maintenance does the Li-Pol 600 mAh cell require?

Recharge every few months during storage to prevent deep discharge; the IP67 rating means no seal lubrication is needed.

At what output does the brake-light mode activate and how bright is it?

The 3D accelerometer triggers the two side red LEDs at 43 lumens when bicycle deceleration is detected.
