A tubelight gets fused when its filament or gas discharge tube fails, often due to factors like age, overheating, or electrical surges. When the filament inside the tube breaks, or the gas within the tube becomes depleted or contaminated, the circuit is interrupted, preventing the light from functioning. Additionally, a faulty starter or ballast can also contribute to a tubelight fusing. Regular maintenance and timely replacement can help prevent these issues.
