What to know before buying
Listing details to confirm
Battery details are inconsistent: the listing identifies an included nonstandard lithium-ion battery and also claims a built-in 1800mAh battery. Runtime is stated as 3.5–39H for the front and 5–10H for the rear, so confirm which operating modes these ranges cover. The 500-lumen output, 70-metre beam distance, waterproof classification and IPX4 claim are listing claims, not independently confirmed here.
