| What is lighting’s function of memorization? | |
| Lighting’s memorization is that when it is turned up at second time, it will resume the brightness at last time. If the light is in “brightness in the bedroom” when it is turned down at last time, then when it is turned up again, it will come back to “brightness in the bedroom” as the last time. | |
