Most homes keep a flashlight, nightlight, and camping lantern separately — each needing its own batteries. Keeplit replaces all three. Screws into any socket, charges automatically, and stays on the moment power fails. No searching. No dead batteries. Up to 48 hours across 3 brightness levels.

Power outages don't warn you. Keeplit does. Screws into any E26/E27 socket, activates automatically when the grid fails — no switches, no panic. 48-hour Guardian Mode, 3 brightness levels. Ready for storms, outages, and everything in between.

How do these emergency light bulbs work?

It’s a normal LED bulb that charges itself while in use. During a power outage, it automatically stays on if the light switch is ON, ensuring you're never left in the dark.

Will the bulb turn on automatically when the power goes out?

Yes, but only if your physical light switch is in the ON position. The bulb needs this closed circuit to detect the power outage and activate its battery.

Is the bulb as bright on battery power as it is on regular electricity?

On battery, the bulb is slightly dimmer than on regular power but remains bright enough for emergency use, ensuring your space is safely and adequately lit.

How long does the light stay on during a power outage?

Fully charged, it lasts 3-5 hrs at 100% brightness, 6-9 hrs at 50%, and an impressive 48 hrs at 10%. This is ample for most outages. For best performance, use it in a frequently used lamp to keep the battery ready for any emergency.

Does the bulb have protection mechanisms during charging?

Yes. It has a smart charging system with Overcharge, Over-discharge, and Short-circuit Protection. It stops charging when full to prevent battery damage and ensure safety. You can leave it in the socket 24/7; it manages itself intelligently
