Operating Instructions
Once paired, you can control your OSRAM LIGHTIFY A19 bulb using your smartphone, tablet, or voice commands through a compatible smart speaker.
1. Adjusting Brightness and Color Temperature
- Use the connected smart hub's application to adjust the brightness (dimming) of the bulb.
- Within the app, select the desired white color temperature, ranging from 2700K (soft white) to 6500K (daylight). This allows for creating different ambiances or optimizing for specific tasks.

2. Voice Control
If you have an Echo or Google Home smart speaker paired with your ZigBee hub, you can use voice commands for hands-free control. Examples include:
- "Alexa, turn on the living room light."
- "Hey Google, dim the bedroom light to 50%."
- "Alexa, set the kitchen light to daylight white."
3. Schedules and Automations
Utilize your smart hub's application to create schedules and automations for your lighting:
- Set lights to turn on or off at specific times (e.g., turn on before you arrive home).
- Create routines for different scenarios (e.g., "Good Morning" routine to gradually brighten lights).
- Enhance security by scheduling lights to turn on and off while you are away, simulating occupancy.
Maintenance
The OSRAM LIGHTIFY A19 LED bulb is designed for long-lasting performance with minimal maintenance. To ensure optimal operation:
- Cleaning: Ensure the bulb is cool and power is off before gently wiping it with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Handling: Avoid dropping the bulb or subjecting it to strong impacts.
- Environment: Use the bulb in dry, indoor environments only, within its specified voltage range (100-120 Volts, 60 Hertz).
Troubleshooting
If you encounter issues with your OSRAM LIGHTIFY A19 bulb, consider the following troubleshooting steps:
- Bulb Not Responding/Not Pairing:
- Ensure the bulb is powered on and within range of your compatible ZigBee smart hub.
- Verify that your hub is powered on and connected to your home network.
- Confirm that you are using a compatible ZigBee hub (e.g., SmartThings, Wink, Echo Plus). This bulb does not connect directly to voice assistants like Echo Dot or Google Home without a hub.
- Try resetting the bulb by turning it off and on several times (usually 5-6 times) until it flashes, indicating it's ready for pairing.
- Check your hub's application for any error messages or specific pairing instructions.
- Flickering or Inconsistent Brightness:
- Ensure the bulb is securely screwed into the socket.
- Verify that the light fixture is not connected to an incompatible dimmer switch. Smart bulbs require constant power and should be controlled digitally via the hub.
- Check for any electrical interference in the area.
- Voice Control Not Working:
- Confirm that your smart speaker (Alexa, Google Assistant) is properly linked to your ZigBee hub account.
- Ensure the bulb is successfully paired with your ZigBee hub and visible in the hub's application.
- Check your smart speaker's app for device discovery or synchronization options.
