Floodlights have the effect of spotlighting, so they are also called spotlights. They can play a very good decorative role in various architectural decorative lighting and commercial space lighting. Many floodlights are installed outdoors, so only good quality can guarantee the effect and life of use. So how to identify the quality of floodlights?
First, use a multimeter to identify
Reputable flood light manufacturers will place many lamp beads in the lamp during production. In order to ensure the rated power, the chip size of these lamp beads meets the requirements and the brightness will be very high. If you want to know whether the quality of the floodlight meets the requirements, you can use a multimeter to measure the floodlight to see if the actual power can reach the calibration value.
Second, identify by tightness
Due to the special use of floodlights, most of them are outdoors, and wind and rain are inevitable. Therefore, the quality of waterproof performance will directly affect the service life of floodlights. The well-sealed floodlight has good waterproof performance, and it is not easy to enter the water. The sealed flood light is generally reflected in the good quality of the lamp shell, and there is a very high level of sealing strip.
Third, identify by weight
Since the flood light converts a part of the energy into heat energy when in use, good heat dissipation is required to dissipate the heat, otherwise it will lead to serious safety hazards. Therefore, high-quality floodlights are often made of enough material for the shell, and the heat sink is relatively thick, so the overall weight will be relatively large. If you want to know which of the two floodlights with the same power is of better quality, just weigh the weight, and the quality of the heavy hand will be better than the light hand.
When choosing a floodlight, if you are hesitant and don't know which one to buy, you can use the three methods described above to identify the quality. This can help you find a floodlight with guaranteed quality from many floodlight products, and a high-quality floodlight can only play a full role after it is installed and used, and has a longer service life.
