What to know before buying

The 4.8 to 24-hour runtime is a mode-dependent claim, not a single guaranteed duration. The listing does not specify which mode corresponds to each runtime or provide a charging time. Treat the lumen, runtime and IPX4 details as listing claims, not independently measured results.
