1. Product Overview
The Keenso E27 Motion Sensor LED Light Bulb is designed for automatic illumination in response to motion. It integrates a PIR (Passive Infrared) motion sensor to detect movement, providing light when needed and conserving energy when not. This bulb is suitable for various indoor and outdoor applications such as corridors, stairwells, garages, and security areas.

4. Operating Instructions
The bulb operates automatically based on its built-in PIR motion sensor and ambient light conditions.
- Automatic Activation: The bulb will automatically illuminate when it detects motion within its sensing range (4-6 meters / 13.12-19.68 feet) in dark conditions.
- Automatic Deactivation: The bulb will automatically turn off approximately 30-60 seconds after motion ceases or disappears from its detection area.
- Light Sensitivity: The bulb is designed to operate primarily in low-light environments. It will not activate during daylight or in brightly lit areas to conserve energy.
