1. Product & Safety
- Are your lumen specs accurately tested?
- Yes. All performance metrics—including lumen output, beam distance, and runtime—are tested according to ANSI/PLATO FL 1 standards using high-performance equipment. Real-world performance may vary slightly based on thermal regulation and battery charge levels.
- Why does my flashlight get hot during use?
- High-lumen flashlights generate significant heat when operating in Turbo or High modes. Our lights feature built-in Advanced Temperature Regulation (ATR) that automatically steps down brightness to prevent overheating and protect internal components.
- How do I unlock my flashlight before first use?
- Most lights ship in Lockout Mode or with an insulating safety tab inside the battery tube to prevent accidental activation during transit. Unscrew the tailcap to remove the yellow insulating film, or press and hold the main button for 3 seconds to unlock.
2. Battery & Charging
- What type of battery does my flashlight use?
- We primarily use high-drain rechargeable lithium-ion batteries (e.g., 18650, 21700). Specific battery requirements are listed on each product page. Always use high-quality button-top or flat-top cells as specified.
- How long does it take to fully charge?
- Charging times depend on battery capacity and the charging source. Built-in USB-C fast charging typically takes 2 to 4 hours. The indicator light will change from Red to Green (or Blue) when fully charged.
3. Shipping & Orders
- Where do you ship, and how long does it take?
- We ship worldwide. Standard international shipping takes 7–15 business days, Other shipping methods subject to circumstances. Order processing takes 1–3 business days.
- Will I have to pay import duties or customs fees?
