If you’re building a private-label UV brand as a wholesaler, treat the lamp like the core of the promise — not just another part on a parts list. In aquarium systems, under-dosing lets pathogens slip through. Over-dosing burns energy and shortens lamp life. We build OEM UVC germicidal lamps around measurable output, repeatable geometry, and stable spectral control, so your brand stands on engineering, not hype. What matters technically These aquarium-grade UVC lamps are low-pressure mercury vapor, giving you a primary 254nm line for germicidal action. Match arc length and power density to your flow rate and chamber volume, and you can hit the required UV dose (mJ/cm²) at the sleeve surface. Peak irradiance is tuned via lamp current and reflector geometry. We use ozone-free quartz sleeves and dichroic-free reflectors to keep output predictable and maintenance straightforward. Lamp life is rated at 8,000–9,000 hours, with controlled output decay. End-of-life is defined by a measured drop in irradiance, not by calendar time. Why it works for OEM With OEM, you own the brand story. We customize so you can standardize on a consistent lamp form factor — pin type, base, and overall length — and keep housings assembling without rework. The payoff is fewer callbacks: stable UVC output means repeatable water clarity and biosecurity in both retail and commercial installs. You also get cost predictability. The lamp is designed to run at its rated current without overdriving, so energy draw and replacement intervals line up cleanly with service plans. Here are the practical details UVC intensity is sensitive to sleeve fouling and water temperature. In saltwater and high-organic applications, plan a cleaning interval and verify dose with a calibrated radiometer. Output also depends on ballast matching — run the lamp only at the specified current, or you’ll invite premature end-of-life. And UVC exposure is hazardous. The lamp must be fully enclosed, with interlocks and warning labeling supplied as part of your OEM assembly.
