How to buy high-quality outdoor LED wall light? Grasping the following three points, we can choose the LED light with really good quality.
1. Look at the processing technology Look at the appearance, observe the details of workmanship, and the appearance is exquisite without acute angles. The color is oxidized, and it is oxidized inside and outside. Because the radiator and lamp of LED wall washing lamp are usually aluminum products. Only aluminum with high purity can be oxidized to produce a good oxidation color, which can ensure the selection of pure aluminum LED wall lamp. 2. Check the luminous efficiency of the lamp The fundamental reason why we choose LED lamps is to save energy and money. Only LED lamps with high luminous efficiency and long life can really save energy and money. They are also LED lamps. The luminous efficiency of efficient LED lamps is more than 50% higher than that of ordinary LED lamps, that is, the energy saving effect is more than 50% higher. In the absence of detection equipment, the comparison method can only be used. LED lamps with the same actual power and traditional lamps are used for the same comparison test. The ones with high brightness are better. The actual power of some LED lamps is much higher than the measured power. Such lamps are not good lamps. This is because the driving efficiency of the lamps is low. Remember to buy LED lamps is to buy their luminous efficiency. Generally speaking, it is to buy brightness rather than power. 3. Judgment method of heat dissipation efficiency Generally, users do not have a thermometer at hand, and can only judge by hand feeling. The ambient temperature will vary according to the seasonal changes, and there will be several different temperatures in the tests on the same day. The heat dissipation effect of LED lamps can be tested only when the temperature rise of lamps is almost unchanged. The heat dissipation effect of LED lamps can be judged by the temperature rise of lamps. In the same environment, two LED lamps with the same heat dissipation structure and power can be lit at the same time. Which lamp will reach the high temperature first, Then the lamp has better heat dissipation, that is, the thermal resistance of the light source and radiator is smaller.
