An inverter bulb is a unique kind of LED light bulb intended to offer backup lighting during power outages. It is also occasionally referred to as an emergency LED bulb or a rechargeable LED bulb. Below is a summary of its salient attributes:
Two-fold Purpose:
When the power is on, it functions like a typical LED bulb and illuminates the area.
It instantly transitions to using its internal battery to offer emergency lights during a power outage.
Integrated Battery:
When the AC power is turned on, an integrated rechargeable battery, usually made of lithium-ion, stores energy in inverter lights.
The lightbulb converts to battery power when the electricity goes out, lasting several hours (typically three to four hours).
