💡 FIRST USE TIP: This flashlight ships from the factory with a "demo mode" that cycles through brightness levels and shuts off — it can look like a defect, but it isn't. If you see this behavior, simply hold the power button for 2–5 seconds to exit demo mode and the light operates normally. We've already deactivated it on this unit, but the mode can reset after a battery change, so keep this tip handy.
