Product overview

This is a rechargeable emergency LED bulb designed for Indian homes that face frequent power cuts. It screws into a standard B22D socket and works like a normal 11W LED bulb while the mains power is on, charging its internal battery at the same time. When the power goes out, the bulb switches to battery mode and, according to the listing, can keep running for up to four hours. That makes it a practical fit for bedrooms, stairwells, kitchens and study areas where you do not want to be left in the dark.

Reasons to consider

• At ₹214.50 per bulb, this is an inexpensive way to add automatic backup lighting to two rooms.
• The B22D base fits the most common household sockets in India, so no rewiring or fixtures are needed.
• Fulfilment by Amazon means straightforward delivery and returns if the unit arrives faulty.
• The 11W output is reasonable for a small to medium room when running on mains power.

Pros and cons

Pros

• Very low per-bulb cost for an emergency/inverter bulb
• Automatic switchover during power cuts, no separate torch or lantern needed
• Charges itself during normal use

Cons

• The 3.8-star rating across roughly 1,687 reviews is middling; expect some mixed experiences with battery life and brightness on backup mode
• The "up to 4 hours" backup figure is a ceiling, not a guarantee — real-world runtime is often lower, especially as the battery ages
• Brightness typically drops in battery mode compared to mains operation
• The advertised 64% discount could not be verified against a confirmed MRP on the page we read

Buyer fit

This suits households in areas with regular load-shedding or unreliable supply, renters who cannot install dedicated inverter wiring, and anyone wanting a cheap safety light for corridors and staircases. If you need high-output backup lighting or guaranteed multi-hour runtime, a dedicated rechargeable lantern or a higher-rated inverter bulb would serve you better.

Final verdict

At ₹429 for a pair, this is a low-risk purchase for basic emergency lighting. The price on the merchant page matches the advertised deal and the pack is in stock, so the offer checks out. Just keep expectations modest: the mid-range review score suggests battery backup and durability vary, so treat the four-hour claim as best-case rather than guaranteed.
