Operation is simple with a yellow power button on the back, allowing you to cycle through four modes: full output (100%), right-side only (50%), left-side only (50%), and off. The charging and power bank ports are protected under a rear rubber-sealed cover, giving the light an IP44 rating for water resistance—safe for use in light rain. To recharge the unit, open the cover and plug a micro USB cable into the port, with the other end going into a USB port or adapter. Three LED indicators show charging progress—each one lights up in sequence until all three are solid, indicating a full charge. These indicators also briefly display the battery level when the light is turned on or when the battery check button is pressed. In addition to lighting, the CLW1150 functions as a portable power bank.
