2. Setup and Installation
These bulbs are designed for simple installation into standard E12 candelabra sockets. Ensure the fixture is suitable for outdoor use and is enclosed to protect the bulb from direct weather exposure.
- Power Off: Before installation, ensure the power supply to the fixture is turned off at the circuit breaker to prevent electrical shock.
- Remove Old Bulb: Carefully unscrew and remove the existing bulb from the fixture.
- Install New Bulb: Screw the Sunco B11 Dusk to Dawn LED bulb into the E12 socket until it is finger-tight. Do not overtighten.
- Restore Power: Turn the power supply back on at the circuit breaker.
The bulb is non-dimmable. Do not use with dimmer switches, as this may cause damage to the bulb or affect its performance.

3. Operating Instructions
The Sunco B11 Dusk to Dawn LED bulb features an integrated photocell sensor that automatically detects ambient light levels. Once installed and powered, the bulb will operate as follows:
- Automatic On: The bulb will automatically illuminate when the ambient light level drops below a certain threshold (at dusk).
- Automatic Off: The bulb will automatically turn off when sufficient ambient light is detected (at dawn).
No manual switching is required for daily operation. Ensure the photocell sensor on the bulb is not obstructed by the fixture, decorations, or other objects, as this can interfere with its ability to detect light levels accurately.
