Safety Information
WARNING: Risk of Electric Shock or Fire.
- Always disconnect power to the fixture before installing, removing, or servicing the bulb.
- Ensure your hands are dry before handling the bulb or fixture.
- Do not use this bulb in fixtures where it may be exposed to water or excessive moisture unless the fixture is specifically rated for such conditions.
- Do not exceed the maximum wattage rating of the fixture. This bulb is 150 watts.
- Handle the bulb carefully. Avoid dropping or subjecting it to strong impacts.
- If the bulb is damaged, do not install or use it.

Setup and Installation
Follow these steps to safely install your replacement light bulb:
- Turn off Power: Locate the circuit breaker or fuse box that controls the power to the light fixture. Turn off the power completely to prevent electric shock. Verify the power is off by attempting to turn on the light switch.
- Allow Cooling: If replacing an incandescent bulb, allow the old bulb to cool down completely before touching it. Hot bulbs can cause severe burns.
- Remove Old Bulb: Carefully unscrew or unclip the old bulb from its socket. For prong-base bulbs, gently pull straight out or follow the fixture's specific removal instructions.
- Inspect Fixture: Check the fixture's socket for any damage, corrosion, or debris. Clean if necessary.
- Install New Bulb: Align the prongs of the new Technical Precision 245 BAY bulb with the corresponding slots in the fixture's socket. Gently push the bulb straight into the socket until it is firmly seated. Do not force the bulb.
- Restore Power: Once the new bulb is securely installed, restore power to the fixture from the circuit breaker or fuse box.
- Test Bulb: Turn on the light switch to confirm the new bulb is working correctly.

Maintenance
Minimal maintenance is required for this light bulb.
- Cleaning: Before cleaning, always turn off the power to the fixture and allow the bulb to cool. Wipe the bulb gently with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Replacement: Replace the bulb when it reaches the end of its operational life (approximately 15 hours average life) or if it becomes damaged. Follow the installation steps for replacement.
Troubleshooting
If the bulb does not illuminate after installation, consider the following:
- No Power: Check if the circuit breaker is tripped or if the fuse is blown. Ensure the light switch is in the "ON" position.
- Improper Installation: Turn off power and re-seat the bulb firmly into the socket. Ensure the prongs are correctly aligned.
- Damaged Bulb: Inspect the bulb for any visible damage (e.g., cracked glass, bent prongs). If damaged, replace it with a new bulb.
- Fixture Issue: If other bulbs also fail in the same fixture, the issue might be with the fixture itself or the wiring. Consult a qualified electrician.
