Weather is normal,no storm etc. Today first time it flickered for 1 second. It happened when i close door in my room ( no more air ) Bulb looking like that: Is this problem with electric in my house or it was bulb? It flickered ( black ) for 1 second and its fine. Should i worry? All deviced and pc working ok. My mother turned oven 2 hours before bulb flicker. Maybe because of oven or it was coincedence?
