An inverter bulb keeps your room lit when the power goes out — no inverter or wiring needed. Each rechargeable emergency LED bulb charges itself in a standard B22 holder while mains power is on, then switches to its built-in battery automatically during a cut for up to 4 hours of backup light. Shop genuine Halonix, Havells, Wipro and LEDVANCE (OSRAM) inverter bulbs with manufacturer warranty, starting at ₹219. Perfect for homes with frequent power cuts, kids’ study rooms, shops and stairwells — screw one in and you’re covered for the next outage.
