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. Allow time to charge.
The battery charges when the bulb receives household power. It cannot charge while the lamp is switched off. The Classic six- and ten-pack bulbs need about 7 to 8 hours for a full charge; follow the instructions for your model, including its first charge.
3. Choose a battery setting.
Our Classic six- and ten-pack bulbs produce 800 lumens on household power. Their battery settings provide less light: the high setting is brighter, while the low setting lasts longer. The product pages show the output and estimated runtime at each level.
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.
