CSIR-CEERI has developed a mercury-free plasma UV (MFP-UV) lamp with novel structural design and optimized gas mixtures that produces strong spectral bands peaking at wavelengths 253 nm and 172 nm along with a weak band peaking at wavelength 265 nm, which is highly useful for water sterilization. The features of the MFP-UV lamp are mercury free, filament less, repairable, eco-friendly technology, instantaneous startup and potential for water and air purification.
