Repeated ignition damages filaments
Insufficient starting voltage causes constant flickering. Frequent high-voltage ignition impacts tungsten filaments, leading to blackened tube ends and broken filaments.
Unstable uneven arc accelerates tube aging
The arc cannot run stably, resulting in concentrated local discharge and premature aging of quartz and mercury amalgam.
High ambient temperature speeds up aging
The underpowered ballast runs under overload and generates excessive heat, raising cabinet temperature and damaging UV lamp materials.
Frequent protection restarts aggravate loss
Overcurrent/thermal protection triggers repeated power cycling, further wearing the lamp.
