Based on the feedback from our customers, users, and fans, we started the work of upgrading the original Auroras keychain flashlights. The improvements are mainly about the battery, operation/UI, and output, etc. Though it utilizes the same LED - CREE XP-G3, thanks to the optimized board driver, the max output it goes to 650 lumens; the optimized driver also brings a better UI and got the PWM issue fixed. As for the runtime, the upgraded Auroras keychain lights are powered by 260mAh rechargeable battery which provides a max 32 hours of runtime at moonlight mode.
