3-LED COB Spot LED Headlight with Motion Sensor - Set includes: 2 pieces - Function: With motion sensor - Modes: Normal mode, Sensor mode - Waterproof rating: IPX4 - Light type: 3-LED COB + LED spotlight I have actually used this item. Charging time is about 1 hour for a full charge when empty with quick charging, and about 1.5 to 2 hours normally. Usage time is about 1.5 hours on COB strong, and about 2 to 3 hours on weak. 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. This item can be lit simultaneously. Power ON ↓ COB strong ↓ COB weak ↓ Spot strong ↓ Spot weak ↓ Power OFF If you hold the switch for more than 3 seconds, the COB and spot lights will turn on simultaneously, and if you press it again, they will 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 it is non-slip, so it does not slip. Waterproof is waterproof only 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. Type...COB light Type...LED light I plan to use Yu-Yu Mercari Post, so I will take it out of the box to reduce the thickness, and the box will be folded and enclosed.
