1, security features
In the landscape, the choice of underwater lights to personal safety as the first element. Must be in accordance with the requirements of the national standard, color with 12V safe voltage underwater light.
2, the lighting function
The lighting function mainly refers to the light-emitting brightness of the light source. It can be under the irradiation height, light-emitting area to choose different power underwater lights.
Another element of the lighting function is the color of the underwater lantern, generally red, yellow, green, blue, white five, according to the application, irradiation and create an atmosphere to choose the object.
3, the appearance of modeling and shell materials
Underwater lights although underwater use, not too prominent. But the appearance and material and the proportion of lamps. If the proportion is too small, resulting in greater buoyancy, easy to loose underwater fixing screws, so that the lamp floating surface and too heavy and difficult to support lighthouse. At the same time, due to long-term use in water, the shell material should have a certain anti-corrosion function, the surface paint layer to be solid.
4, the economy
The economy of underwater lights refers to the sum of one-time investment and operating expenses of lamps and lights. In general, better quality underwater lights, the lamp price is higher, longer life, smaller operating costs, on the contrary, the poor quality of the underwater lights, although the price is cheap, but often due to leakage, leakage and Resulting in blindness, not only increased operating costs, and some even affect the acceptance of the entire project.
