Press the "+" button to increase brightness and the "-" button to decrease it. #### Timer Settings {#_timer_settings} **8-Hour:** Press the timer button once and the 8-hour indicator light will turn on. **12-Hour:** Press the timer button twice and the 12-hour indicator light will turn on. **18-Hour:** Press the timer button three times and the 18-hour indicator light will turn on. #### How to Set Up a 24-Hour Cycle {#_how_to_set_up_a_24_hour_cycle} Example: If the timer is set to 8 hours at 5 PM, the light will stay on until 1 AM, then automatically turn on again at 5 PM the next day, following the same 8-hour cycle. This will repeat daily until the power is cut or the timer is manually changed. The same logic applies to the 12-hour and 18-hour settings. #### Brightness Memory After Power Loss {#_brightness_memory_after_power_loss} After a power outage, turning the light back on will restore the previously set brightness level. #### Timer Memory After Power Loss {#_timer_memory_after_power_loss} After a power outage and restart, the memory function is cleared and the timer settings must be reset.
