Here are the general steps to install a tube light:

1. Turn off the power: Before you begin, turn off the power to the circuit you'll be working on. You can do this by switching off the circuit breaker or removing the fuse.

2. Gather the tools: You will need a screwdriver, wire cutters, wire strippers, and a voltage tester.

3. Remove the old fixture: If there's an existing fixture, remove it by unscrewing the mounting bracket and disconnecting the wires.

4. Install the mounting bracket: Attach the new mounting bracket to the ceiling or wall using screws provided.

5. Connect the wires: Connect the wires from the electrical box to the wires on the tube light, following the manufacturer's instructions. Typically, this involves connecting the black or red wire to the black or red wire, the white wire to the white wire, and the green or bare wire to the green or bare wire.

6. Install the tube light: Insert the tube light into the fixture and snap it into place. Make sure it's securely installed.

7. Turn on the power: Once you're done, turn the power back on and test the tube light to ensure it's working correctly.
