Customer feedback is always one of the motivations pushing us to do better, the new Aurora A3 (upgraded) is one of the results of listening to our customers/users. The max output is increasing to 650 lumens compared to the original Aurora A3 550 lumens though the LED is the same CREE XP-G3 S5 (Still offer an option of High CRI LED, Nichia 219C). The improvement is not only on the output (we think it's not that important for keychain lights) but also on the operation / UI, we make the Strobe a hidden feature and the light has memory mode. And 5mm longer in the length makes holding the light and one-handed operation more comfortable. A pocket clip is a key to the small flashlight, we also improve it to make it stronger and more durable.
