Review on 💡 Safelumin SA19-800U27 4PK: Rechargeable Light Bulbs - A Lifeline in Home Power Outages - Doubles as LED Light Bulb by Sue Baccam

This product is amazing. It's like a regular lightbulb - you plug it into an outlet, turn it on - it glows! Switch off - no light! Switch on the light! Power out - LIGHT! When you press the black button, the light will flash to indicate the battery level. I tested this light by turning the switch off - worked as advertised. I've been using it for several months now. Leave the light on all the time - since it's LED, it uses little power. This is a brilliant design and should be installed in every home especially if you have children and want a light in case of a power outage.
