How to choose led underwater lamp
The following aspects should be considered when choosing LED underwater lamps:
1. Safety function: in the landscape, LED underwater lamp selection is the first element of personal safety. In accordance with the requirements of the national standard, the LED underwater lamp with 12V safety voltage must be used.
2. Lighting function: lighting function mainly refers to the brightness of the light source. It can select LED underwater lamps with different power according to the height of illumination and the area of projection. Another element of illumination function is the color of underwater color lights, which generally have five kinds: red, yellow, green, blue and white. It can be selected according to the application situation, the object of illumination and the atmosphere created.
3. Appearance and shell materials: underwater lanterns, though underwater, are not very visible. But the appearance and material are related to the proportion of lamps and lanterns. If the proportion is too small, it will produce greater buoyancy, easy to loosen the fixed screw of underwater color lights, so that the lamps float on the water surface and too heavy to support the lamp holder. At the same time, due to long-term use in water, its shell material should have a certain anti-corrosion function, the surface paint should be firm.
4. Economy: the economy of underwater lanterns refers to the sum of one-time investment and operating costs of lamps and lanterns. Generally speaking, the underwater color lamps with better quality have higher price, longer service life and lower operation cost. On the contrary, the underwater color lamps with worse quality, though cheap, often cause blindness due to leakage of water and electricity, which not only increases the operation cost, but also affects the acceptance and acceptance of the whole project.
