1. Module input power: 0.8 ± 10% W UVC working current: 100 ± 10mA 2. Ultraviolet light power test: using an ultraviolet integrating sphere, the ultraviolet light power output is not less than 4 mW. 3. Ultraviolet wavelength range test: 270nm-280nm 4. efficiency: continuous irradiation [water tank capacity (L) x20] min, E. coli inactivation rate ≥99.9%. efficiency: Irradiation per hour [water tank capacity (L) x5] minnatural colony Less than50cfu/ml (within 200h) 5. Life test: input 100mA current at normal temperature LED works continuously for 10000 hours, power attenuation ≤50% no abnormal phenomena in other performance High and low temperature test: the product can work reliably within the temperature range of 30°C~60°C; The product can be reliably stored in the temperature range of -30°C ~ 100°C. (Ambient temperature for use: ≤60°C) Material: Plastic + metal colour: As shown Package Contents: 5 x module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
