Current-controlled driver with ATR thermal regulation

Why this matters: Buck and boost drivers step down or step up voltage efficiently using switching inductors, maintaining flat regulated output as cell voltage drains rather than dimming progressively like FET/linear direct drives.

Dual switch operation: Tail switch for tactical on/off, side e-switch for mode control. Supports smooth ramping (1-1900lm) and stepped modes (Eco-Low-Med-High-Turbo). ATR (Advanced Temperature Regulation) prevents overheating by automatically adjusting brightness. Mode memory remembers last brightness level. Includes 3000mAh button-top 18650 battery. Total weight with battery: 114g. USB-C charging built-in for convenience.
