Software, user interface, modes

Mode memoryyes
Ramping modeyes

The Anduril firmware is popular among flashlight enthusiasts. It is versatile, easy to use, and lets you customize flashlight behavior. The flashlight has mode memory. It remembers the mode you were using when the light was last turned off. It stays in that mode when you turn it on again. The light doesn't have predefined brightness levels or fixed modes. Instead, the ramping mode lets you adjust the light smoothly within a specific range.

Designers created the strobe function to produce a disorienting or attention-grabbing effect. The SOS code starts three short signals. Then, three long signals follow. Finally, there are three short signals again.
