Summary

The Cyanlamp M12R from Cyansky combines many good ideas: A spotlight for throw, that can also be used as a headlamp when clipped to a cap. A floodlight that evenly illuminates at close range. There are also RGB LEDs with various effects and work great as a beacon or marker. The flashlight can be attached either with the large clip, an eyelet or the integrated magnet. It can also be switched on and off with a simple gesture control.

However, there is still room for improvement in the implementation: Starting with the cool white light with low CRI, the unattractive color shift of the spotlight, to the simple driver that cannot keep the brightness constant. In addition, it doesn’t indicate whether you turn on the spotlight or floodlight.
