Product Overview
The 40 Litre is a Ultrawave UV sterilizer box that uses ultraviolet light to eliminate bacteria, viruses, and other pathogens from everyday objects without heat, chemicals, or moisture. With a 40 L capacity, it accommodates a wide range of items including smartphones, baby bottles, feeding accessories, toys, keys, spectacles, and personal care items. The 15 W - 30 WW UV-C Tube Lamp lamp operating at 254 nmnm falls within the germicidal UV-C range that disrupts the DNA of microorganisms, preventing reproduction and rendering them inactive. Disinfection efficiency of Up to 99.9% means the vast majority of common bacteria and viruses on object surfaces are eliminated in a single sterilization cycle. A complete sterilization cycle takes only 15-45 minutes, making it practical for daily use without requiring extended periods away from frequently used items like phones. The automatic shutoff when the lid is opened is a critical safety feature — UV-C radiation is harmful to eyes and skin, so the circuit immediately cuts power when the chamber is accessed during operation. The UV-C LED lifespan of 6000-8000 hours hours means thousands of sterilization cycles before replacement is needed. Ultrawave provides a 6 Months - 1 Year product warranty.

Engineering Analysis
UV-C sterilization works through photochemical disruption rather than thermal or chemical kill mechanisms. When UV-C photons at 254 nmnm wavelength strike nucleic acids (DNA/RNA) in microorganisms, they cause thymine dimers to form — covalent bonds between adjacent thymine bases that prevent normal DNA transcription and replication. The result is cellular death without leaving chemical residues on treated surfaces. The 15 W - 30 WW lamp intensity determines the UV dose delivered per unit time. UV dose (mJ/cm²) is the product of irradiance and exposure time — to achieve 99.9% inactivation of E. coli, a minimum dose of approximately 7 mJ/cm² is required. The 15-45 minutes cycle of the 40 Litre is calibrated to achieve this dose at the designed lamp-to-surface distance. The lid-open safety shutoff in the 40 Litre uses a simple magnetic or mechanical interlock that breaks the lamp power circuit immediately when the lid is lifted. This is not merely a software switch — it is a hardware interlock that cannot be bypassed by software failure, ensuring UV-C exposure to skin and eyes is impossible during normal operation. UV-C LED technology differs from traditional low-pressure mercury lamps in both safety and longevity. LEDs contain no mercury, making disposal safer and eliminating the breakage hazard of glass mercury tubes. With a 6000-8000 hours-hour lifespan, the LEDs will outlast most product use cycles without replacement, maintaining consistent germicidal output throughout.
