【Precise 253.7nm Narrowband Output - Ozone Free】Emitting a peak wavelength of 253.7nm with narrower waveform than standard lamps, delivering almost 20% higher energy density for more effective destruction of microorganism DNA. This specific wavelength does not produce harmful ozone and is therefore safer for fish and aquatic life while maintaining strong sterilisation performance.
【For Electronic Ballast Only】 Important Compatibility Note: This PLL lamp with 2G11 socket (4-pin, 225mm length) is designed exclusively for electronic ballasts (ECG). It offers flicker-free instant start and constant performance. ️ Not compatible with magnetic (inductive) ballasts - please check the ballast type of your device before ordering to avoid damage.
Optimised for the European 230 V mains and voltage fluctuations: Specially designed for the German and European power grids, this lamp has a 220-240 V wide voltage starter. Compared to standard lamps with only 220V, it ensures stable UVC performance and longer life - even with voltage fluctuations in the mains for maximum reliability.
High-purity quartz glass - 96% UVC permeability: Made of high-quality quartz glass, this 18W UVC lamp offers UVC transmission of up to 96% for maximum germicidal efficiency. Ideal for water treatment, it eliminates up to 99.9% of algae, bacteria and micro-organisms in ponds, aquariums and water treatment plants.
Certified safety and robust construction: Fully compliant with CE, RoHS, UKCA and FCC certifications for safe operation and environmental compatibility. Made with durable components for continuous use - a reliable replacement for your water steriliser, pond clarifier or UV filtration system.
