LED underwater lamp, LED underwater lamp, transformer characteristic
In theory, the safest approach is to place the high pressure (220V) part above the surface of the water, and the lower part to be placed in the water.
WaterproofDo a good job of water supply and transformer, transformer and underwater lamp connection waterproof - use waterproof junction box, sealant.
Distance from the transformer to the lampSince the wire itself has a resistance, it will share part of the voltage, resulting in the underwater voltage of the underwater lamp is less than 12V. Therefore, the distance of the underwater lamp from the transformer outlet should not be too far. If the distance is too far, the number of transformers can be increased.
Configure the transformer according to the total power of the LED underwater lampIn general, the use of transformers is 75%, more appropriate, that is: 100W transformer drive less than 75W lights. Pay attention to the inlet and outlet of the transformer.
Transformer type:Common Transformers: plain coil transformers.Rain proof transformer: rainproof case.Waterproof transformer: full waterproof transformer filled with glue. It can be immersed in the bottom water.
