The Sleep Time setting allows you to create an interval when your Filimin will only light up dimly and briefly in response to your touch or that of someone in your group. However, if your Filimin is already lit, it will not suddenly turn off when the sleep interval begins. In that situation, you can touch it to turn it off.
For example, if you set a sleep interval of 11:00 PM to 7:00 AM and you or a loved one touches your Filimin at 10:55 PM, your Filimin will remain lit at 11:00 PM. However, you can simply touch it and it will shut off. If a lamp in your group is touched again between 11:00 PM and 7:00 AM, your Filimin will light up very briefly, just bright enough so you know it is working, but dim enough so as not to disturb you.
