On the production floor, germicidal performance isn’t a guess—it’s dose, pure and simple. You get that dose from spectral output and irradiance. When your process has to kill pathogens reliably, a generic bulb is rolling the dice. We build UVC germicidal bulbs with E26 and E27 bases to deliver a repeatable 254nm output, backed by real lamp salt formulation.
What matters under the hood
Germicidal action peaks at 254nm, and that means nailing the mercury vapor spectrum. We tune the fill ratio and the doping of the emitting salts to shape the spectral profile—cutting out the UVA/UVB you don’t want and pushing the UVC line where it counts. The quartz envelope is chosen for high 254nm transmission and ozone-free operation, and the internal amalgam holds arc temperature steady so output stays consistent across duty cycles. Peak irradiance is maintained at the target distance, which is what gives you predictable microbial reduction.
Why this matters on the line
You need instant-on performance without drift during warm-up. Our E26/E27 bulbs hit operating irradiance right away, delivering the energy density required for complete microbial inactivation on surfaces and in air streams. Because the spectrum is tailored, you don’t waste energy outside the germicidal band—so you get more effective dose per watt, solid lamp-to-lamp uniformity, and longer effective life with controlled output decay.
The shop-floor details
Before you swap bulbs, confirm fixture compatibility. E26 and E27 sockets share similar thread dimensions, but lamp length and starting voltage have to match the ballast and reflector geometry. Running the bulb in an enclosure without proper airflow risks thermal runaway and can cut life short. Always make sure your system’s ballast supports the UVC lamp’s starting characteristics and power draw.
