Stay Lit During Any Power Outage — Indoors or Outdoors

The E27 LED Rechargeable Emergency Bulb is the smart, versatile lighting solution every home needs. With a built-in 1500mAh rechargeable battery, this bulb automatically switches to emergency mode the moment the power goes out — keeping your home, porch, garden, or campsite illuminated without skipping a beat.

Specifications

How It Works

1. Normal operation: When power is available, the bulb functions exactly like any standard LED — turn it on and off with your wall switch as usual.
2. Power failure during use: If the power cuts out while the light is on, it automatically switches to battery-powered emergency mode. You can still use your switch to turn it on/off.
3. Power failure when light is off: If power fails while the switch is off, the emergency mode won't activate automatically — but you can turn it on manually using the switch.
4. Charging: Install in a powered E27 socket with the switch on; the battery charges passively while the bulb operates normally.

Perfect For
