Tronic Emergency LED Bulb 9W-A80 B22 Daylight White Rechargeable

Our review

This is a rechargeable LED bulb from Tronic, built to keep lighting a room when the regular power supply fails. It screws into a standard B22 bayonet socket, so it can replace an ordinary bulb in a bedside lamp, hallway fitting or office desk light without rewiring. It suits households and workplaces in areas where outages are frequent, and anyone who wants a light source that doubles as normal lighting and a backup. Before buying, confirm your fixture takes a B22 fitting rather than a screw base, and think about how long you need light to last after the power goes, since runtime depends on the battery and is not stated here. Compared with a torch or a separate emergency lamp, this stays in the socket and comes on where you already expect light, but it gives one bulb's worth of coverage rather than lighting a whole room. A plain LED bulb is cheaper if outages are rare; a rechargeable one earns its place if they are routine. Available on Sokonia.
