Do you believe that the LED light bulb can still be lit for 3 hours?

Sudden power cuts at night, the interior is dark and uncomfortable. British Litonics Ltd. has introduced an iViTi On, an LED bulb that remains bright after a power outage, for up to 3 hours of illumination. It sounds amazing, it is simple to say it. Originally, the built-in 600 mA rechargeable battery of the bulb is charged when the power is connected, and the bulb works normally. Once the power is turned off, the bulb automatically switches to the battery mode and continues to emit light. This LED bulb is suitable for general luminaires and requires no additional wiring. In terms of brightness, the 8 watt iViTi On is equivalent to a 60 watt ordinary lamp. The bulb will be available by the end of this year, but the price is still unclear.
