3-LED COB Spot LED Headlight with Motion Sensor - Set includes: 2 pieces - Features: With motion sensor - Modes: Normal mode, sensor mode - Waterproof rating: IPX4 - Light type: 3-LED COB + LED spotlight I've actually used this item. Charging time is about 1 hour for a full charge when empty, using quick charging. Normally, it takes about 1.5 to 2 hours. Usage time is about 1.5 hours on COB high. 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 the surroundings widely. The LED spotlight is focused on a single point. You can use them separately depending on the application, but they cannot 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 flash simultaneously. 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 each time you wave your hand left and right. The back of the light is all rubber, so it's flexible and fits the shape of your head or helmet and doesn't slip, so it won't shift. Waterproof is only for water from above, such as rain, but water will enter from below, so it cannot be used underwater. The switch is on the side, so it can be operated with wet hands.
