Safety Information
For your safety, please adhere to the following guidelines:
- Use only in indoor or covered outdoor locations. Do not expose directly to water.

Installation and Operation
Follow these steps to set up your bulb:

- Select Color Temperature: Adjust the switch on the bulb before installation. Options range from 2700K (Soft White) to 6500K (Daylight).
- Install: Turn off power to the fixture, install the bulb, and restore power.
- Performance Tips: For optimal results, install the bulb facing downwards in a fixture at a height of 9ft to 10ft. The microwave sensor can detect motion through thin walls or glass. Avoid using in metal fixtures, as they may interfere with sensor performance.
Troubleshooting
If you encounter issues, consider the following:
- Intermittent Blinking: The sensor may be detecting motion through walls or being triggered by external movement like wind-blown plants. Ensure the bulb is at least 7ft away from other motion sensor bulbs.
- Bulb Never Turns On: Ensure the bulb is installed facing downwards, as upward installation significantly reduces detection range.
- Daytime Activation: The bulb is designed to activate upon detecting motion regardless of the time of day.
Warranty and Support
This product includes a ten-year limited warranty based on 3 hours of daily use. If the bulb fails due to defects in materials or workmanship, please contact your local Home Depot store with proof of purchase for a replacement or store credit.
