Question on notifications - power out to a bulb

Is it possible to be notified if a bulb loses power ?

Use case
I want to be notified if one of the bulbs loses power because someone accidentally flipped the switch on a lamp that I have a zwave bulb in.

Not without additional equipment - like a current transducer connected to a dry contact zigbee or zwave relay.

I don't think there are any bulbs that can report they have lost power. This isn't a hub limitation, rather that there are no bulbs with battery backup.

What type of lamp? Table lamp or overhead lamp?
