Tronic Emergency LED Bulb Rechargeable 9W B22 Daylight White

Our review

This Tronic bulb is a rechargeable LED that fits a standard B22 bayonet socket, so it works in most ordinary light fixtures. It runs at 9W and gives a daylight white light, and its main purpose is to stay lit when mains power fails, which makes it useful in homes, shops, and workspaces where outages are frequent. It suits anyone who wants basic backup lighting without wiring a separate emergency lamp. Before buying, check that your fixture takes a B22 base, since bayonet and screw fittings are not interchangeable, and think about how many bulbs you need for the rooms you use most. Compared with a plain LED bulb, you trade a little efficiency for built-in backup; compared with a torch or rechargeable lamp, you get light exactly where your existing fixture already is. No specifications beyond the above are given, so confirm runtime and charging details on the listing before you commit.
