Safety indicators against electric shock
The anti-shock index of national standard for lamps and lanterns can be divided into four categories: O, I, II and III. At the same time, the national standard clearly stipulates that the underwater lighting lamps for swimming pool, fountain pool, water splashing pool and other similar places shall be class III anti-shock protection lamps. The operating voltage of the external and internal circuit shall not exceed 12V.
Rated working voltage
The rated working voltage of the lamp is the electrical parameter index of the lamp. It directly determines the operating environment of the lamp, that is, the actual working voltage must be consistent with the rated working voltage. Otherwise, either because voltage is too high and burn out the light source, or because too low and cannot achieve the lighting effect
