Setup
- Installation: Ensure the light fixture switch is in the OFF position. Carefully screw the EBULB into a standard E26 light socket. Do not use in enclosed fixtures that may trap heat.
- Initial Charge: Once installed, turn the light switch ON. The bulb will illuminate and begin charging its internal battery. Allow the bulb to remain powered for at least 8 hours to ensure a full initial charge.
- Testing (Optional): To verify emergency functionality, you can temporarily turn off the circuit breaker for the installed fixture. The EBULB should automatically illuminate. Remember to turn the breaker back on after testing.

Important Note:
The EBULB is designed to function optimally in single-bulb fixtures. It may not operate correctly in multi-bulb fixtures or fixtures with dimmers, as these can interfere with the bulb's power sensing and charging mechanisms.
Operating Instructions
Normal Operation:
When the main power supply is active, the EBULB functions as a regular LED light bulb. Use your existing light switch to turn it ON or OFF as needed.
Emergency Operation (Power Outage):
In the event of a power failure, the EBULB will automatically switch to its internal battery power and illuminate, provided the light switch for the fixture is in the ON position. If the light switch was OFF when the power failed, simply turn the switch ON to activate the emergency light.

Portable Use:
To use the EBULB as a portable light source:
- Carefully unscrew the EBULB from its fixture.
- Attach the included holder hook to the base of the bulb. The holder hook often includes a small switch to turn the bulb ON/OFF when used portably.
- Activate the bulb using the switch on the holder hook. You can then hold it as a torch or hang it for hands-free illumination.

Maintenance
- Cleaning: Ensure the bulb is cool and the power is off before cleaning. Wipe the bulb with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Battery Care: The internal battery is designed for long-term use and self-charges. No specific user maintenance is required for the battery beyond ensuring the bulb is regularly used in a powered socket to maintain its charge.
- Storage: If storing the bulb for an extended period, ensure it is fully charged before storage and recharge it every 3-6 months to maintain battery health.
