checking the lamp by the tool
We switch on each ultraviolet lamp and use the electric spark detector to check the ultraviolet lamp before packaging. Such the video which show to us. If the color of ultraviolet lamp is blue, that is mean the lamp is okay. If the color of the ultraviolet lamp is pink, that is mean the lamp isn’t okay. If the lamp without the color, that is mean the lamp is broken.
