How to choose the LED tube to see the starting performance The starting performance of the LED fluorescent lamp has one characteristic: it is on when it is energized, and will not flicker; weigh, compare the weight with each other, the heavier is better than the lighter, and the heavier means that the materials are used well. Look at the temperature when the switch is working: The temperature of the LED fluorescent lamp should be low during normal operation. Otherwise, the life span of the LED lamp is very short. At the same time, when the energy-saving lamp is lit, it flickers rapidly or fluctuates very harshly, indicating that the energy-saving lamp has a quality problem. After a few minutes of power-on, there should be a temperature, which proves that the heat dissipation is good, and the aluminum substrate used for heat dissipation. Without temperature, it is a fiberglass board, and the heat cannot be dissipated; a real LED fluorescent lamp. From the perspective of the lamp, the shape and size of the lamp are better and more consistent, the product consistency is good, and the quality assurance is easier. Of course, there can be no cracks or looseness between the interfaces. The led tube must choose the kind of engineering plastic flame-retardant plastic PC shell. Ordinary plastic deformation and flammability, the aluminum tube must be bright, aviation aluminum. There is also the outer packaging of the LED tube. The national compulsory product LED lighting manufacturer marked the following on the package: rated voltage range, rated power, and rated frequency. In general, the printed high-quality products are of good quality, clear handwriting, not easy to fall off, wipe with a soft damp cloth, the logo is clear and identifiable, the manufacturer's trademark and related certification marks. LED energy-saving lamps are very popular among people and are suitable for indoor lighting in office buildings, shopping malls, restaurants, schools, homes, factories, etc.
