Product Information
Full details
This Bailey LED-lamp (MPN: 143857) is designed for professionals seeking energy-efficient replacements for ceramic metal halide lamps in commercial settings like shops, display windows, and museums. Its key benefit is providing a bright, neutral white light while consuming less energy. A crucial caveat is its limited suitability for fixtures with high ambient temperatures (up to 40°C) and enclosed spaces, requiring careful installation to prevent overheating. This compact, single-ended LED bulb is dimmable and offers an 8W output equivalent to 20W traditional lamps.

FAQs
What type of lamps can this LED replace?
This Bailey LED-lamp is designed as a direct replacement for ceramic metal halide lamps with a G12 base.
Do I need to keep the ballast and igniter from my old lamp?
No, you must disconnect and remove the ballast, capacitor, and igniter before installing this LED lamp. It is designed to run directly from mains voltage.
What is the maximum temperature this lamp can withstand?
The LED light source is suitable for temperatures up to 40°C inside the fixture. Overheating can cause malfunction.
Can I use this lamp in a completely enclosed fixture?
It is not recommended for use in tight, enclosed fixtures or where the reflector is very close to the LED, as this can lead to overheating. It is often advised to remove the glass or cover from the fixture to ensure proper ventilation.
Is this LED lamp dimmable?
Yes, this Bailey LED-lamp is dimmable, allowing for adjustable light levels.
What is the light color temperature?
The lamp provides a neutral white light with a color temperature of 4000K.
How does the 8W power compare to traditional lamps?
The 8W LED lamp is equivalent in brightness to a 20W traditional lamp, offering significant energy savings.
Troubleshooting
Lamp does not turn on.
Verify that the power supply is connected and that the ballast, capacitor, and igniter have been correctly removed. Ensure the lamp is properly seated in the G12 socket.
Lamp flickers or turns off intermittently.
This is likely due to overheating. Check the ambient temperature inside the fixture. Ensure there is adequate ventilation and that the reflector is not too close to the LED. Consider removing the fixture's glass cover if applicable.
Reduced brightness or color shift.
Overheating can degrade LED performance over time. Ensure the fixture meets the maximum temperature requirement (40°C) and has sufficient airflow. Clean any dust or debris from the lamp and fixture.
Lamp does not dim correctly.
Confirm that the fixture's dimmer switch is compatible with LED technology. Not all LED dimmers are universal. Ensure the dimmer is set to an appropriate range for the LED lamp.
