Motion Sensor 3-COB Spot LED Headlight - Set includes: Set of 2 - Features: With motion sensor - Modes: Normal mode, Sensor mode - Waterproof rating: IPX4 - Light type: 3-COB + LED spotlight I actually used this item. Charging time is about 1 hour for a full charge from empty with quick charging, and about 1.5 to 2 hours normally. Usage time is about 1.5 hours on COB high, and about 2 to 3 hours on low. It varies slightly depending on usage conditions. The built-in battery is one Li-Ion 18650 battery. Charging port: Type-C The COB light is a diffused type that illuminates a wide area. The LED spotlight is focused on a single point. This product can be lit simultaneously. Power ON ↓ COB High ↓ COB Low ↓ Spot High ↓ Spot Low ↓ Power OFF If you hold the switch for 3 seconds or more, the COB and spot lights will turn on simultaneously, and pressing it again will make them flash. When the power is turned on, the red lamp on the switch side lights up. When the motion switch is turned on, the green lamp also lights up. The light turns ON and OFF every time you wave your hand left and right. The back of the light is all rubber, so it is flexible and fits the shape of the head and helmet, and does not slip, so it does not shift. The waterproof feature is only for water from above, such as rain, but water can enter from below, so it cannot be used underwater. The switch is on the side, so it can be operated with wet hands.
