1. Introduction
The Feit Electric LED Dusk to Dawn Sensor Intellibulb is an advanced A19 LED light bulb designed for automatic illumination. Featuring a built-in light sensor, it detects ambient light intensity to automatically turn on at dusk and off at dawn, eliminating the need for manual controls or timers. This bulb offers an 800-lumen output, equivalent to a 60W incandescent bulb, while consuming only 8.8W, providing significant energy savings. It emits a 2700K soft white light, creating a warm and inviting atmosphere. With a long lifespan and instant full brightness, this bulb is suitable for various indoor and outdoor applications.

2. Setup and Installation
Installing your Feit Electric LED Dusk to Dawn bulb is a simple process. Follow these steps for proper setup:
- Power Off: Before installation, ensure the power to the light fixture is turned off at the switch and the circuit breaker to prevent electrical shock.
- Screw in Bulb: Carefully screw the LED bulb into a standard E26 medium base light fixture. Ensure it is securely tightened.
- Position Sensor: For optimal dusk to dawn functionality, position the bulb so that its built-in light sensor faces natural sunlight. This allows the sensor to accurately detect ambient light levels.
- Restore Power: Once the bulb is installed and positioned, restore power to the fixture. The bulb will automatically begin its dusk to dawn operation.

3. Operating Instructions
The Feit Electric LED Dusk to Dawn bulb is designed for automatic, hands-free operation:
- Automatic On/Off: The integrated light sensor automatically turns the bulb on when ambient light levels drop (dusk) and turns it off when sufficient light is detected (dawn). Keep the fixture switch in the 'ON' position for continuous automatic operation.
- Instant Brightness: The bulb provides instant full brightness of 800 lumens with no warm-up time required.
- Color Temperature: This specific model provides a 2700K Soft White light, which is ideal for creating a warm and cozy ambiance. Some variants of Feit Electric bulbs may feature a selectable color temperature switch (e.g., 5000K, 4000K, 2700K) on the bulb itself. If your bulb has this feature, select your preferred color temperature before installation.

4. Maintenance
LED bulbs require minimal maintenance. To ensure longevity and optimal performance:
- Cleaning: Periodically wipe the bulb and fixture with a soft, dry cloth to remove dust and debris. Ensure the power is off before cleaning.
- Avoid Harsh Chemicals: Do not use abrasive cleaners or solvents, as these can damage the bulb's surface or internal components.
- Inspect Fixture: Occasionally check the light fixture for any signs of wear or damage.
5. Troubleshooting
If you encounter issues with your Feit Electric LED Dusk to Dawn bulb, consider the following:
- Bulb Not Turning On/Off Automatically:
- Ensure the light sensor on the bulb is not obstructed by the fixture, shadows, or other objects. The sensor needs direct exposure to ambient light.
- Verify that the fixture's power switch is continuously in the 'ON' position.
- Check for external light sources (e.g., streetlights, other outdoor lights) that might be illuminating the sensor, preventing it from turning on at dusk or turning off at dawn.
- Buzzing Noise: Some users have reported a buzzing noise. If this occurs, ensure the bulb is fully screwed into the socket. If the issue persists, it may indicate an incompatibility with the fixture's wiring or a specific electrical condition.
- Inconsistent Operation: If the bulb turns on too early or too late, or stays on/off unexpectedly, re-evaluate the sensor's exposure to light throughout the day. Adjust the bulb's orientation if possible to optimize sensor performance.
