Crompton 20W Emergency LED Bulb B22
During a power cut, this 20W B22 bulb switches to battery mode automatically as long as the wall switch stays on, providing up to three hours of backup from a built-in lithium-ion cell that recharges on its own once mains power returns. A three-step dimming function lets you trade brightness for longer backup duration during extended outages. It operates across a wide 170–270V input range and carries 4kV surge protection, both practical features given the variable grid conditions in many Indian cities.
