Soonfire FD39 USB Rechargeable Bright Bike Light
[FD39]

This flashlight has a lot of pros, such as using the standard 18650 battery, which is my favorite type. It also has built-in charging and excellent brightness, especially in the ultra-bright mode. The good color rendition (CRI) makes colors appear vivid and accurate, and the blue/red indicator on the side button shows power and charging status. However, it??s somewhat large for a 18650 flashlight and a bit too big to put in a pocket. Here??s a side-by-side comparison with my Zebralight SC64w flashlight, which has about the same illumination power. The Soonfire is larger due to the built-in charging circuit and better heat-sink, which prevent it from getting hot too quickly. If you??re looking for something super compact in this power range and don??t mind taking out the battery to charge it, check out the Zebralight.
