Our lamps can be customized to operate either with a motion sensor or on a timed schedule, according to your needs. The motion sensor setting triggers the lamp to full 100% brightness when someone approaches and reduces to 30% brightness once they leave, extending battery lasting time. The time schedule option allows for setting different brightness levels at specific times—for example, 100% brightness for the first 4 hours, 50% for the next 4 hours, and 25% for the last 4 hours, to conserve energy. Both brightness levels and timing can be customized to fit your requirements.
