how to choose voltage for led wall washer

Is it better to choose high-voltage or low-voltage for led wall washer?

Low-voltage wall washer

Advantages of low-voltage wall washer:

1. Safety: low-voltage lamps are generally DC12V/24/36V, which are all safe for human body to withstand voltage. In the case of wire skin cuts or other reasons for leakage, there is no harm to human body contact;

2. Use: Because the circuit is a circuit, a small part is used;

3. No stroboscopic phenomenon: avoid stroboscopic phenomenon in use;

4. Small size: Because of the complex circuit volume, small detection can be avoided.

Disadvantages of low-voltage wall washer:

1. It needs to be connected to a low-voltage power supply, which is not common with the commonly used 220V;

2. Short transmission distance: Within a limited wire diameter range, the transmission distance is short, and the wire is required to be thicker, which increases the cost of the wire, because the wire has resistance, which will cause a voltage drop.

High-voltage wall washer:

Advantages of high-voltage wall washer:

1. Easy to use: It can directly replace the existing 220V circuit lamps without the need for circuit conversion or circuit modification;

2. Strong versatility: good compatibility with the accessories on the market;

3. The transmission distance is long. The same size wire has a longer transmission distance than low voltage.

shortcoming:

1. High voltage is dangerous;

2. The volume is not easy to be miniaturized;

3. The alternating current has strobe.

In addition, which one is more power-efficient about high-voltage and low-voltage wall washers? The power consumption is calculated according to the power. The wall washer of the same power has the same high and low voltage power consumption.

In general, there is no absolute good or bad for high-pressure and low-pressure wall washers, and they each have their own advantages and disadvantages. High-voltage or low-voltage is selected according to the actual application, and the high-voltage wall washer is already a very mature lamp. If it is not a shoddy product and violent installation and construction, the safety problem is still very guaranteed.
