Everyday bulb. Built-in backup.
Start with a compatible lamp, give the battery time to charge, and learn the portable hook control before an outage.
1. Check your lamp.
Match the bulb to a 120V fixture with a compatible E26 screw socket and enough clearance for the bulb. Turn off power and let the old bulb cool before changing it. Socket size alone does not establish compatibility with dimmers, enclosed fixtures or multi-bulb circuits; check the supplied instructions and fixture requirements.
2. Charge during normal use.
The battery charges when the bulb receives mains power. A lamp that is switched off at the wall cannot keep charging. For the six- and ten-pack Classic models described here, the listed full-charge time is 7–8 hours. Follow the instructions for your exact pack and allow a full initial charge before relying on backup light.
3. Know the difference between modes.
The Classic six- and ten-pack specifications list 800 lumens on mains power. Battery operation uses less power and produces less light. The available brightness settings trade stronger illumination for a shorter runtime. Color temperature describes the appearance of the light, not how long the battery lasts.
4. Learn the hook cap.
The supplied hook cap turns a charged bulb into a portable light. Use its switch as instructed, attach the hook securely and keep it away from water. Never touch the metal base while the bulb is connected to mains power. Do not use water, improvised wiring or household objects to test electrical contacts.
5. Try your setup ahead of time.
Backup behavior depends on the fixture and circuit as well as the bulb. Follow the product manual to test the actual lamp you intend to use. Keep a separate flashlight available and do not treat a household rechargeable bulb as a replacement for required emergency or exit lighting.
