Choose LED fluorescent tube-5 tricks are enough
Methods used when choosing LED fluorescent tubes
LED fluorescent tubes are very professional, and most people don’t know how to distinguish them. Here are 5 tips to tell you that you can choose led tubes without an instrument.
1. Look at the packaging and labels
National compulsory product LED lighting manufacturers mark 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 mark is clearly identifiable, the manufacturer's trademark and related certification marks.
2. Look at the appearance of the LED tube
Real LED fluorescent tube. 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.
3. Working temperature
When the LED fluorescent tube is in normal operation, the temperature should be low. 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. There is no temperature, it is a fiberglass board, and the heat cannot be dissipated
4. Look at the startup performance
The start-up of the LED fluorescent tube has a feature: it lights up when it is powered on, and does not flicker
5. Weigh the weight, compare the specific weight with each other, the heavier is better than the lighter, and the heavier indicates that the material is used well
