Important Safety Information
WARNING: Electrical shock hazard. Disconnect power before installation or servicing.
- Do not exceed the specified voltage (28 Volts). Using the bulb with higher voltage can cause premature failure or damage.
- Handle bulbs with care. Avoid touching the glass directly with bare hands, as oils can reduce bulb life. Use a clean cloth or gloves if necessary.
- Ensure the bulb is securely seated in the socket to prevent flickering or poor connection.
- Do not use in wet locations unless the fixture is specifically rated for such use.
- Dispose of used bulbs according to local environmental regulations.
Setup and Installation
Unpacking
Carefully remove the bulbs from their packaging. Inspect each bulb for any signs of damage, such as cracks in the glass or a broken filament. Do not install damaged bulbs.
Installation Steps
- Step 1: Disconnect Power. Before attempting any installation, ensure the power supply to the fixture is completely turned off at the circuit breaker or fuse box. This is crucial to prevent electrical shock.
- Step 2: Identify Socket Type. Confirm that your fixture uses a miniature wedge W2.1x9.5d base socket, which is compatible with this bulb. Refer to the product specifications for base dimensions.
- Step 3: Insert Bulb. Gently push the bulb's wedge base into the socket until it is firmly seated. Do not force the bulb, as this may damage the base or the socket.
- Step 4: Restore Power. Once the bulb is securely installed, restore power to the fixture from the circuit breaker or fuse box.
- Step 5: Test Operation. Turn on the light switch to verify the bulb is functioning correctly.

Maintenance
These bulbs require minimal maintenance due to their design and intended use.
Cleaning
If cleaning is necessary, ensure the power is off and the bulb is cool to the touch. Gently wipe the glass with a soft, dry, lint-free cloth. Do not use liquid cleaners or abrasive materials, as these can damage the bulb's surface or internal components.
Replacement
When the bulb reaches the end of its lifespan (approximately 1000 hours), it will cease to illuminate. To replace, follow the "Installation Steps" outlined in the Setup and Installation section, ensuring power is disconnected before removing the old bulb and installing a new one.
Troubleshooting
If your Sunlite T3.25 Mini-Tube Bulb is not functioning as expected, refer to the following common issues and solutions:
Bulb Does Not Light
- No Power: Check if the power supply to the fixture is on. Verify the circuit breaker or fuse for the circuit.
- Loose Connection: Ensure the bulb is fully and securely inserted into the socket. A loose connection can prevent the bulb from lighting.
- Incorrect Voltage: Confirm that the fixture's voltage matches the bulb's 28V requirement. Using an incompatible voltage can prevent operation or damage the bulb.
- Burned Out Bulb: If the filament appears broken or the bulb has been in use for an extended period (beyond its approximate 1000-hour lifespan), it may have reached the end of its life. Replace with a new bulb.
- Damaged Socket: Inspect the socket for any visible damage, corrosion, or bent contacts. If the socket is damaged, consult a qualified electrician for repair or replacement.
