Walk into a cold-storage facility, and the physics hits you fast. At those temperatures, UVC germicidal lamps don’t fail because the lamp is “bad.” They fail because the power supply can’t keep up with what the cold does to the arc. Conventional magnetic ballasts lose their grip on regulation. Current drops. Spectral output collapses. On packaging lines, that means surface disinfection isn’t complete—so you’re leaving room for pathogens and putting compliance at risk.

What matters under the hood

We built this electronic ballast to keep lamp current stable down to -20°C. It holds the arc power needed so the 254nm UVC output stays consistent, and it prevents the current sag that happens when mercury vapor pressure plummets. Ignition is fast—under 0.8 seconds—and lamp power stays within ±3% across the full temperature swing. Peak irradiance stays predictable, so your dose calculations for microbial kill rates don’t go sideways. Over the lamp’s 25,000-hour rated life, output drift stays under 8%.
