T5 6w8w Mosquito Killing Lamp Set BL Mosquito-Lured Lamp Sticky Fly Light Tube 365nm Blue Purple Lig

● product clarity chart

the principle of luminescence is the same as that of common white tubes. The difference is that ultraviolet rays are emitted at micro-special wavelength. Ultraviolet radiation is generated by fluorescent powder coated on the inner tube wall, and fluorescent powder converts arc energy into ultraviolet radiation. The unique fluorescent powder coating can effectively emit ultraviolet radiation of special wavelength (the radiation here refers to the emitted light wave), this wavelength of ultraviolet and light blue visible rays particularly attracts mosquitoes and Insecta to approach.

Although mosquito killing lamp looks almost the same as ordinary white tube when there is no power supply, the production cost of lamp tube is higher than that of white tube!!!

● reference wavelength (mosquito killer tube/lamp) 

after lighting, the lamp tube emits blue visible light (generally, the luminous flux of visible light is not very high), and at the same time, ultraviolet light with high intensity invisible to the naked eye is about 390nm, which has certain fluorescence effect; special light blue fluorescent powder (for Mosquitoes?, Flies and flying insects have obvious temptation effect), which minimizes visible light and harmful ultraviolet light, but does not affect the luminous effect; It can absorb visible light and transmit ultraviolet light, mosquitoes and insects can see the lights in the dark sight, so they are easily attracted.
