The Philips Battery Backup Lamp B22 is a dual-purpose rechargeable LED bulb for everyday room lighting and temporary illumination during electricity interruptions. When mains power is available, it functions as a normal LED lamp and charges its internal battery. If the supply fails while the lamp circuit remains switched on, the lamp changes to battery-powered light, helping keep essential areas visible.
Automatic Backup Lighting
The integrated battery and changeover circuit remove the need to locate a torch immediately when power goes off. Backup brightness and operating duration are normally lower than full mains performance and vary with the exact regional lamp configuration, battery charge, age and ambient conditions.
B22 Lamp Fitting
This version is made for a B22 bayonet pin holder. Confirm the fitting before purchase: B22 and E27 screw lamps are not interchangeable without changing the holder. Switch off the circuit at the distribution board before installing or removing the lamp.
Two Light-Colour Options
The live Shopify product contains Cool Day Light and Warm White variants. Cool Day Light provides a crisp functional tone for kitchens, passages and work areas, while Warm White creates a softer atmosphere for bedrooms and living spaces. Select the required variant before checkout.
Correct Fixture and Circuit Use
Use the lamp only in a compatible open fitting with the electrical arrangement specified by Philips. Backup lamps depend on the lamp circuit and switching path to detect a power failure. They are not substitutes for certified emergency-exit lighting or legally required building emergency systems.

- Provides normal LED lighting and power-cut backup from one lamp.
- Changes to battery mode automatically when correctly installed.

Installation, Care and Safety
Have the circuit checked by a qualified electrician if the backup function does not operate as expected. Isolate mains power before installation. Do not install in an incompatible holder, enclosed fitting, wet location or dimmer circuit unless the exact package permits it. Keep the lamp switched on long enough to maintain charge, avoid repeated rapid switching and allow ventilation around the body. Replace the product if the casing, cap or battery system is damaged, swollen or unusually hot.
