Stay safe when the lights go out
Power cuts needn't leave you fumbling in the dark. This 20W Emergency LED Bulb is your answer to unexpected outages — it works as a standard everyday bulb and quietly keeps your home lit when mains power fails.
Installation couldn't be simpler. Just screw it into any E27 socket you already have, whether in your home, office, or on the landing. There's no rewiring, no fuss. While the power's on, it charges silently via its dual battery system (2 x 4500mAh). The moment the lights cut out, an intelligent sensor springs into action, automatically switching to battery power so you're never caught off guard.
You'll get bright, clean cool white light at 6000K with an output of 990 lumens — enough to see clearly and move safely around your space. It's the kind of peace of mind that costs very little to run.
