2. Safety Information
WARNING: Risk of electric shock. Disconnect power before servicing.
- Always disconnect line voltage before installing, replacing, or servicing the ballast.
- Power must be reset after replacing the lamp.
- Ensure proper grounding by connecting the green wire or through the ballast enclosure.
- This ballast is suitable for recessed use.
- Do not install insulation above or within 3 inches of the ballast sides to prevent overheating.
- Use only 4.0kV pulse rated lampholders for screw base lamps.
- Do not connect the RED or BLUE lead to neutral.
- Installation should be performed by a qualified electrician in accordance with national and local electrical codes.
3. Product Overview
The PHILIPS Advance e-Vision IMH-100-D-BLS is an electronic ballast designed for (1) 100W Metal Halide lamp. It features IntelliVolt® technology, allowing operation on 120V to 277V, 50/60Hz input. Key features include Lamp End-of-life (EOL) Detection, high power factor, and thermal protection.

4. Setup and Installation
Follow these steps for proper installation of the ballast:
- Power Disconnection: Ensure that the main power supply to the circuit is completely disconnected before beginning installation.
- Mounting: Securely mount the ballast in a suitable location, ensuring adequate ventilation. Maintain a minimum clearance of 3 inches from any insulation.
- Wiring Connections: Refer to the wiring diagrams below for correct connections.
- Connect the RED lead to the center terminal of the lamp (for screw base lamps).
- Do not connect the RED or BLUE lead to neutral.
- Ensure proper grounding using the green wire or by grounding through the ballast enclosure.
- Lamp Installation: Install a 100W Metal Halide lamp (ANSI M90 or M140) into a 4.0kV pulse rated lampholder.
- Power Restoration: Once all connections are secure and verified, restore power to the circuit.

5. Operating Instructions
The PHILIPS Advance e-Vision IMH-100-D-BLS ballast is designed for automatic operation. Once properly installed and powered, it will ignite and operate the 100W Metal Halide lamp. The IntelliVolt® feature automatically adjusts to input voltages between 120V and 277V.
- Lamp End-of-Life (EOL) Detection: The ballast is equipped with EOL detection to safely shut down the lamp when it reaches the end of its operational life, preventing potential hazards.
- Minimum Starting Temperature: The ballast is designed to start lamps reliably down to -30°C (-20°F).
6. Maintenance
Minimal maintenance is required for the ballast itself. Regular inspection of the lighting system is recommended.
- Cleaning: Keep the ballast and surrounding area free from dust and debris to ensure proper heat dissipation.
- Lamp Replacement: When replacing a lamp, always disconnect power first. After installing a new lamp, power must be reset to restore output.
- Thermal Protection: The ballast is thermally protected. If it shuts down due to overheating, allow it to cool down and ensure proper ventilation before resetting power.
7. Troubleshooting
If the lamp fails to operate, consider the following:
- No Light:
- Check if the power supply is connected and active.
- Verify all wiring connections are secure and correct according to the diagrams.
- Inspect the lamp for damage or if it has reached its end-of-life. Replace if necessary and reset power.
- Ensure the lampholder is rated for 4.0kV pulse.
- Intermittent Operation:
- Check for loose connections.
- Ensure the ballast is not overheating due to insufficient ventilation or high ambient temperatures.
- Lamp Cycling: This may indicate a lamp nearing its end-of-life or an issue with the ballast's EOL detection. Replace the lamp first. If the issue persists, consult technical support.
