Armytek Crystal Pro Blue F07101B 220 lm white 30 lm red 600 mAh IP67 10 m drop

Compact Keychain Flashlight with Dual Light Modes

The Armytek Crystal Pro Blue F07101B is a rechargeable LED flashlight designed for everyday carry and cycling safety. It delivers 220 lumens of white light and 30 lumens of steady red light from a translucent polycarbonate body that creates a wide flood beam. A built-in 600 mAh Li-Pol battery charges via Micro USB with colour status indication. The IP67 rating ensures dust protection and submersion resistance at one metre for thirty minutes, while the housing withstands drops from ten metres.

Integrated Brake Light and Versatile Mounting

A built-in 3D accelerometer detects deceleration to activate a bicycle brake light mode, boosting the red output to 43 lumens using two side LEDs for increased rear visibility. The included bicycle mount secures the light to a bike, while the compact form factor allows it to sit in a pocket or bag for quick access. One-button operation with a double-click colour change keeps controls simple in the dark. The robust Micro USB socket supports repeated charging cycles without a proprietary cable.

Upgrade from Basic Keychain Lights

This model replaces single-colour keychain lights that lack a brake-light function or impact-rated construction. The jump is worth it for cyclists who want automatic brake signalling and a durable, waterproof housing that survives hard drops. It is not suited for users who need a focused long-throw beam, higher maximum output for trail navigation, or a larger battery capacity for multi-day use without recharging.
